If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.

You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \rrather than the linux standard \n or better still the suspenders and belt approach of windows with \r\n.

pandas.read_csv(filename, sep='\t', lineterminator='\r')

You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

import codecs

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set

df = pandas.read_csv(doc, sep='\t')

Create Table as select (CTAS) is possible in Hive.

You can try out below command:

CREATE TABLE new_test 
    row format delimited 
    fields terminated by '|' 
    STORED AS RCFile 
AS select * from source where col=1

1. Target cannot be partitioned table.
2. Target cannot be external table.
3. It copies the structure as well as the data

Create table like is also possible in Hive.

1. It just copies the source table definition.

You can use cut with a delimiter like this:

with space delim:

cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv

with tab delim:

cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv

I gave you the version of cut in which you can extract a list of intervals...

Hope it helps!

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

The way to determine the coordinates depends on what element you're working with. For circles for example, the cx and cy attributes determine the center position. In addition, you may have a translation applied through the transform attribute which changes the reference point of any coordinates.

Most of the ways used in general to get screen coordinates won't work for SVGs. In addition, you may not want absolute coordinates if the line you want to draw is in the same container as the elements it connects.

Edit:

In your particular code, it's quite difficult to get the position of the node because its determined by a translation of the parent element. So you need to get the transform attribute of the parent node and extract the translation from that.

d3.transform(d3.select(this.parentNode).attr("transform")).translate

Working jsfiddle here.

I bumped into this problem lately with Windows 10 from another direction, and found the answer from @JonSkeet very helpful in solving my problem.

I also did som further research with a test form and found that when the the current culture was set to "no" or "nb-NO" at runtime (Thread.CurrentThread.CurrentCulture = new CultureInfo("no");), the ToString("yyyy-MM-dd HH:mm:ss") call responded differently in Windows 7 and Windows 10. It returned what I expected in Windows 7 and HH.mm.ss in Windows 10!

I think this is a bit scary! Since I believed that a culture was a culture in any Windows version at least.

I just saw another question very similar to this!

Here is the canonical NORTHWIND (spelled just slightly different for some reason) database example.

SELECT *
FROM [NORTHWND].[dbo].[Products]

SELECT CategoryId,
           MAX( CASE seq WHEN 1 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 2 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 3 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 4 THEN ProductName ELSE '' END )
      FROM ( SELECT p1.CategoryId, p1.ProductName,
                    ( SELECT COUNT(*) 
                        FROM NORTHWND.dbo.Products p2
                        WHERE p2.CategoryId = p1.CategoryId
                        AND p2.ProductName <= p1.ProductName )
             FROM NORTHWND.dbo.Products p1 ) D ( CategoryId, ProductName, seq )
     GROUP BY CategoryId ;

Here is a flexible way to do deal with multiple indented lines without using heredoc.

  echo 'Hello!'
  sed -e 's:^\s*::' < <(echo '
    Some indented text here.
    Some indented text here.
  ')
  if [[ true ]]; then
    sed -e 's:^\s\{4,4\}::' < <(echo '
      Some indented text here.
        Some extra indented text here.
      Some indented text here.
    ')
  fi

Some notes on this solution:

• if the content is expected to have simple quotes, either escape them using \ or replace the string delimiters with double quotes. In the latter case, be careful that construction like $(command) will be interpreted. If the string contains both simple and double quotes, you'll have to escape at least of kind.
• the given example print a trailing empty line, there are numerous way to get rid of it, not included here to keep the proposal to a minimum clutter
• the flexibility comes from the ease with which you can control how much leading space should stay or go, provided that you know some sed REGEXP of course.

Something else you can try if you are having issues encoding to 'utf-8' and want to go cell by cell you could try the following.

Python 2

(Where "df" is your DataFrame object.)

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = unicode(x.encode('utf-8','ignore'),errors ='ignore') if type(x) == unicode else unicode(str(x),errors='ignore')
            df.set_value(idx,column,x)
        except Exception:
            print 'encoding error: {0} {1}'.format(idx,column)
            df.set_value(idx,column,'')
            continue

Then try:

df.to_csv(file_name)

You can check the encoding of the columns by:

for column in df.columns:
    print '{0} {1}'.format(str(type(df[column][0])),str(column))

Warning: errors='ignore' will just omit the character e.g.

IN: unicode('Regenexx\xae',errors='ignore')
OUT: u'Regenexx'

Python 3

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = x if type(x) == str else str(x).encode('utf-8','ignore').decode('utf-8','ignore')
            df.set_value(idx,column,x)
        except Exception:
            print('encoding error: {0} {1}'.format(idx,column))
            df.set_value(idx,column,'')
            continue

Old topic, but never clearly answered. I've been working on similar as well, and found the solution:

The pipe (|) in this code sample from Austin isn't the delimiter, but to pipe the ForEach-Object, so if you want to use it as delimiter, you need to do this:

Import-Csv H:\Programs\scripts\SomeText.csv -delimiter "|" |`
ForEach-Object {
    $Name += $_.Name
    $Phone += $_."Phone Number"
}

Spent a good 15 minutes on this myself before I understood what was going on. Hope the answer helps the next person reading this avoid the wasted minutes! (Sorry for expanding on your comment Austin)

There have been a few good comments about adding the shebang line to the beginning of the script. I'd like to add a recommendation to use the env command as well, for additional portability.

While #!/bin/bash may be the correct location on your system, that's not universal. Additionally, that may not be the user's preferred bash. #!/usr/bin/env bash will select the first bash found in the path.

Use Node's native child_process api to accomplish this.

No need for third party libs. Two lines of code.

const child_process = require("child_process");
child_process.execSync(`zip -r DESIRED_NAME_OF_ZIP_FILE_HERE *`, {
  cwd: PATH_TO_FOLDER_YOU_WANT_ZIPPED_HERE
});

I'm using the synchronous API. You can use child_process.exec(path, options, callback) if you need async. There are a lot more options than just specifying the CWD to further finetune your requests. See exec/execSync docs.

Please note: This example assumes you have the zip utility installed on your system (it comes with OSX, at least). Some operating systems may not have utility installed (i.e., AWS Lambda runtime doesn't). In that case, you can easily obtain the zip utility binary here and package it along with your application source code (for AWS Lambda you can package it in a Lambda Layer as well), or you'll have to either use a third party module (of which there are plenty on NPM). I prefer the former approach, as the ZIP utility is tried and tested for decades.

There is a huge difference between the below two:

• splitting a single delimited string
• splitting delimited strings for multiple rows in a table.

If you do not restrict the rows, then the CONNECT BY clause would produce multiple rows and will not give the desired output.

• For single delimited string, look at Split single comma delimited string into rows
• For splitting delimited strings in a table, look at Split comma delimited strings in a table

Apart from Regular Expressions, a few other alternatives are using:

• XMLTable
• MODEL clause

You can also use following Node.js module to do it with ease:

https://www.npmjs.com/package/mssql-to-csv

var mssqlExport = require('mssql-to-csv')

    // All config options supported by https://www.npmjs.com/package/mssql 
    var dbconfig = {
        user: 'username',
        password: 'pass',
        server: 'servername',
        database: 'dbname',
        requestTimeout: 320000,
        pool: {
            max: 20,
            min: 12,
            idleTimeoutMillis: 30000
        }
    };

    var options = {
        ignoreList: ["sysdiagrams"], // tables to ignore 
        tables: [],                  // empty to export all the tables 
        outputDirectory: 'somedir',
        log: true
    };

    mssqlExport(dbconfig, options).then(function(){
        console.log("All done successfully!");
        process.exit(0);
    }).catch(function(err){
        console.log(err.toString());
        process.exit(-1);
   });

writelines() does not add line separators. You can alter the list of strings by using map() to add a new \n (line break) at the end of each string.

items = ['abc', '123', '!@#']
items = map(lambda x: x + '\n', items)
w.writelines(items)

As of Hive 0.14, the CSV SerDe is a standard part of the Hive install

ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'

(See: https://cwiki.apache.org/confluence/display/Hive/CSV+Serde)

LOAD DATA INFILE '/home/userlap/data2/worldcitiespop.txt' INTO TABLE cc FIELDS TERMINATED BY ','LINES TERMINATED BY '\r \n' IGNORE 1 LINES;

• IGNORE 1 LINES to skip over an initial header line containing column names
• FIELDS TERMINATED BY ',' is to read the comma-delimited file
• If you have generated the text file on a Windows system, you might have to use LINES TERMINATED BY '\r\n' to read the file properly, because Windows programs typically use two characters as a line terminator. Some programs, such as WordPad, might use \r as a line terminator when writing files. To read such files, use LINES TERMINATED BY '\r'.

Alright, I deserve to be throttled. definitely an RTM but not for WooCommerce, for Wordpress. Solution found due to a JOLT cola (all hail JOLT cola).

TASK: Field named 'related_product_ids' added to a custom post type. So when that post is displayed mini product displays can be displayed with it.

PROBLEM: Was having a problem getting the multiple ids returned via WP_Query.

SOLUTION:

$related_id_list          = get_post_custom_values('related_product_ids');
    // Get comma delimited list from current post
$related_product_ids      = explode(",", trim($related_id_list[0],','));
    // Return an array of the IDs ensure no empty array elements from extra commas
$related_product_post_ids = array( 'post_type' => 'product', 
                                   'post__in'  => $related_product_ids,
                                   'meta_query'=> array( 
                                        array( 'key'    => '_visibility',
                                               'value'  => array('catalog', 'visible'),'compare' => 'IN'
                                        )
                            ) 
);      
    // Query to get all product posts matching given IDs provided it is a published post
$loop = new WP_Query( $related_posts );
    // Execute query
while ( $loop->have_posts() ) : $loop->the_post(); $_product = get_product( $loop->post->ID );
    // Do stuff here to display your products 
endwhile;

Thank you for anyone who may have spent some time on this.

According to Yashu's instructions, I wrote the following function (it's PL/SQL code, but it should be easily adaptable to any other language).

FUNCTION field(str IN VARCHAR2) RETURN VARCHAR2 IS
    C_NEWLINE CONSTANT CHAR(1) := '
'; -- newline is intentional

    v_aux VARCHAR2(32000);
    v_has_double_quotes BOOLEAN;
    v_has_comma BOOLEAN;
    v_has_newline BOOLEAN;
BEGIN
    v_has_double_quotes := instr(str, '"') > 0;
    v_has_comma := instr(str,',') > 0;
    v_has_newline := instr(str, C_NEWLINE) > 0;

    IF v_has_double_quotes OR v_has_comma OR v_has_newline THEN
        IF v_has_double_quotes THEN
            v_aux := replace(str,'"','""');
        ELSE
            v_aux := str;
        END IF;
        return '"'||v_aux||'"';
    ELSE
        return str;
    END IF;
END;

Try this

Sub Txt2Col()
    Dim rng As Range

    Set rng = [C7]
    Set rng = Range(rng, Cells(Rows.Count, rng.Column).End(xlUp))

    rng.TextToColumns Destination:=rng, DataType:=xlDelimited, ' rest of your settings

Update: button click event to act on another sheet

Private Sub CommandButton1_Click()
    Dim rng As Range
    Dim sh As Worksheet

    Set sh = Worksheets("Sheet2")
    With sh
        Set rng = .[C7]
        Set rng = .Range(rng, .Cells(.Rows.Count, rng.Column).End(xlUp))

        rng.TextToColumns Destination:=rng, DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote,  _
        ConsecutiveDelimiter:=False, _
        Tab:=False, _
        Semicolon:=False, _
        Comma:=True, 
        Space:=False, 
        Other:=False, _
        FieldInfo:=Array(Array(1, xlGeneralFormat), Array(2, xlGeneralFormat), Array(3, xlGeneralFormat)), _
        TrailingMinusNumbers:=True
    End With
End Sub

Note the .'s (eg .Range) they refer to the With statement object

And using the joiner from http://jinja.pocoo.org/docs/dev/templates/#joiner

{% set comma = joiner(",") %}
{% for user in userlist %}
    {{ comma() }}<a href="/profile/{{ user }}/">{{ user }}</a>
{% endfor %}  

It's made for this exact purpose. Normally a join or a check of forloop.last would suffice for a single list, but for multiple groups of things it's useful.

A more complex example on why you would use it.

{% set pipe = joiner("|") %}
{% if categories %} {{ pipe() }}
    Categories: {{ categories|join(", ") }}
{% endif %}
{% if author %} {{ pipe() }}
    Author: {{ author() }}
{% endif %}
{% if can_edit %} {{ pipe() }}
    <a href="?action=edit">Edit</a>
{% endif %}

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

Try this (change instances of ' ' to ',' or whatever delimiter you want to use)

CREATE FUNCTION dbo.Wordparser

  @multiwordstring VARCHAR(255),
  @wordnumber      NUMERIC

Have you tried the import text function.

string.Split() returns an array - you can convert it to a list using ToList():

listStrLineElements = line.Split(',').ToList();

Note that you need to import System.Linq to access the .ToList() function.

We faced the same problem:

ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log

In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.

I figured this out a few months back and blogged about it. The summary is:

If you want to use smtplib to send email to multiple recipients, use email.Message.add_header('To', eachRecipientAsString) to add them, and then when you invoke the sendmail method, use email.Message.get_all('To') send the message to all of them. Ditto for Cc and Bcc recipients.

Your format string is wrong. Change it to

insert = DateTime.ParseExact(line[i], "M/d/yyyy hh:mm", CultureInfo.InvariantCulture);

try

states.split()

it returns the list

['Alaska',
 'Alabama',
 'Arkansas',
 'American',
 'Samoa',
 'Arizona',
 'California',
 'Colorado']

and this returns the random element of the list

import random
random.choice(states.split())

split statement parses the string and returns the list, by default it's divided into the list by spaces, if you specify the string it's divided by this string, so for example

states.split('Ari')

returns

['Alaska Alabama Arkansas American Samoa ', 'zona California Colorado']

Btw, list is in python interpretated with [] brackets instead of {} brackets, {} brackets are used for dictionaries, you can read more on this here

I see you are probably new to python, so I'd give you some advice how to use python's great documentation

Almost everything you need can be found here You can use also python included documentation, open python console and write help() If you don't know what to do with some object, I'd install ipython, write statement and press Tab, great tool which helps you with interacting with the language

I just wrote this here to show that python is great tool also because it's great documentation and it's really powerful to know this

Here is another way how you can format using 'f-string' format:

print(
    f"{'Trades:':<15}{cnt:>10}",
    f"\n{'Wins:':<15}{wins:>10}",
    f"\n{'Losses:':<15}{losses:>10}",
    f"\n{'Breakeven:':<15}{evens:>10}",
    f"\n{'Win/Loss Ratio:':<15}{win_r:>10}",
    f"\n{'Mean Win:':<15}{mean_w:>10}",
    f"\n{'Mean Loss:':<15}{mean_l:>10}",
    f"\n{'Mean:':<15}{mean_trd:>10}",
    f"\n{'Std Dev:':<15}{sd:>10}",
    f"\n{'Max Loss:':<15}{max_l:>10}",
    f"\n{'Max Win:':<15}{max_w:>10}",
    f"\n{'Sharpe Ratio:':<15}{sharpe_r:>10}",
)

This will provide the following output:

Trades:              2304
Wins:                1232
Losses:              1035
Breakeven:             37
Win/Loss Ratio:      1.19
Mean Win:           0.381
Mean Loss:         -0.395
Mean:               0.026
Std Dev:             0.56
Max Loss:          -3.406
Max Win:             4.09
Sharpe Ratio:      0.7395

What you are doing here is you are saying that the first column is 15 chars long and it's left justified and second column (values) is 10 chars long and it's right justified.

Joke? :)

How about echo "12|23|11" | awk '{split($0,a,"|"); print a[3] a[2] a[1]}'

This is my output:

p2> echo "12|23|11" | awk '{split($0,a,"|"); print a[3] a[2] a[1]}'
112312

so I guess it's working after all..

As mentioned by @Tom, the cut and awk approaches actually don't work for CSVs with quoted strings. An alternative is a module for python that provides the command line tool csvfilter. It works like cut, but properly handles CSV column quoting:

csvfilter -f 1,3,5 in.csv > out.csv

If you have python (and you should), you can install it simply like this:

pip install csvfilter

Please take note that the column indexing in csvfilter starts with 0 (unlike awk, which starts with $1). More info at https://github.com/codeinthehole/csvfilter/

Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.

Pandas is a library for handling data in Python, preferred by many Data Scientists.

Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.

In your case:

    import pandas

    def create_dictionary(filename):
        my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
        # Here you can delete the dataframe columns you don't want!
        del my_data['B']
        del my_data['D']
        # ...
        # Now you transform the DataFrame to a list of dictionaries
        list_of_dicts = [item for item in my_data.T.to_dict().values()]
        return list_of_dicts

# Usage:
x = create_dictionary("myfile.csv")

#splits string according to delimeters 
'''
Let's make a function that can split a string
into list according the given delimeters. 
example data: cat;dog:greff,snake/
example delimeters: ,;- /|:
'''
def string_to_splitted_array(data,delimeters):
    #result list
    res = []
    # we will add chars into sub_str until
    # reach a delimeter
    sub_str = ''
    for c in data: #iterate over data char by char
        # if we reached a delimeter, we store the result 
        if c in delimeters: 
            # avoid empty strings
            if len(sub_str)>0:
                # looks like a valid string.
                res.append(sub_str)
                # reset sub_str to start over
                sub_str = ''
        else:
            # c is not a deilmeter. then it is 
            # part of the string.
            sub_str += c
    # there may not be delimeter at end of data. 
    # if sub_str is not empty, we should att it to list. 
    if len(sub_str)>0:
        res.append(sub_str)
    # result is in res 
    return res

# test the function. 
delimeters = ',;- /|:'
# read the csv data from console. 
csv_string = input('csv string:')
#lets check if working. 
splitted_array = string_to_splitted_array(csv_string,delimeters)
print(splitted_array)

A sample - write multiple rows with boolean column (using example above by GaretJax and Eran?).

import csv
RESULT = [['IsBerry','FruitName'],
          [False,'apple'],
          [True, 'cherry'],
          [False,'orange'],
          [False,'pineapple'],
          [True, 'strawberry']]
with open("../datasets/dashdb.csv", 'wb') as resultFile:
    wr = csv.writer(resultFile, dialect='excel')
    wr.writerows(RESULT)

Result:

df_data_4 = pd.read_csv('../datasets/dashdb.csv')
df_data_4.head()

Output:

   IsBerry  FruitName
   0    False   apple
   1    True    cherry
   2    False   orange
   3    False   pineapple
   4    True    strawberry

The answer provided by @Jean provides a working but obscure solution (although it doesn't handle trailing spaces)

As an alternative consider a vba user defined function (UDF)

Function RightWord(r As Range) As Variant
    Dim s As String
    s = Trim(r.Value)
    RightWord = Mid(s, InStrRev(s, " ") + 1)
End Function

Use in sheet as
=RightWord(A2)

How about a list?

mystring.split(",")

It might help if you could explain what kind of info we are looking at. Maybe some background info also?

EDIT:

I had a thought you might want the info in groups of two?

then try:

re.split(r"\d*,\d*", mystring)

and also if you want them into tuples

[(pair[0], pair[1]) for match in re.split(r"\d*,\d*", mystring) for pair in match.split(",")]

in a more readable form:

mylist = []
for match in re.split(r"\d*,\d*", mystring):
    for pair in match.split(",")
        mylist.append((pair[0], pair[1]))

SELECT * FROM TABLENAME WHERE FIND_IN_SET(@search, column)

If it turns out your column has whitespaces in between the list items, use

SELECT * FROM TABLENAME WHERE FIND_IN_SET(@search, REPLACE(column, ' ', ''))

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html

I don't think you need to

In python you seldom need to convert a string to a list, because strings and lists are very similar

Changing the type

If you really have a string which should be a character array, do this:

In [1]: x = "foobar"
In [2]: list(x)
Out[2]: ['f', 'o', 'o', 'b', 'a', 'r']

Not changing the type

Note that Strings are very much like lists in python

Strings have accessors, like lists

In [3]: x[0]
Out[3]: 'f'

Strings are iterable, like lists

In [4]: for i in range(len(x)):
...:     print x[i]
...:     
f
o
o
b
a
r

TLDR

Strings are lists. Almost.

Try this...  
  <script type="text/javascript">

    $(document).ready(function(){

    $("#find").click(function(){
        var username  = $("#username").val();
            $.ajax({
            type: 'POST',
            dataType: 'json',
            url: 'includes/find.php',
            data: 'username='+username,
            success: function( data ) {
            //in data you result will be available...
            response = jQuery.parseJSON(data);
//further code..
            },

    error: function(xhr, status, error) {
        alert(status);
        },
    dataType: 'text'

    });
        });

    });



    </script>

    <form name="Find User" id="userform" class="invoform" method="post" />

    <div id ="userdiv">
      <p>Name (Lastname, firstname):</p>
      </label>
      <input type="text" name="username" id="username" class="inputfield" />
      <input type="button" name="find" id="find" class="passwordsubmit" value="find" />
    </div>
    </form>
    <div id="userinfo"><b>info will be listed here.</b></div>

This will work for sure, and I actually tried it out:

Give it a Try !!!

I prefer this because it prevents a single item list with an empty item if your source string is empty:

  IEnumerable<string> namesList = 
      !string.isNullOrEmpty(names) ? names.Split(',') : Enumerable.Empty<string>();

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

Use

cut -b COLUMN_N_BEGINS-COLUMN_N_UNTIL INPUT.TXT > OUTPUT.TXT

-f doesn't work if you have "tabs" in the text file.

Here is a way to do it in the shell:

FIELD=2
cut -f $FIELD * | sort| uniq -c |sort -nr

This is the sort of thing bash is great at.

You can fix this by listing the columns in you LOAD DATA statement. From the manual:

LOAD DATA INFILE 'persondata.txt' INTO TABLE persondata (col1,col2,...);

...so in your case you need to list the 99 columns in the order in which they appear in the csv file.

Try

rows = tabDelimitedTable.split("[" + newLine + "]");

This should solve the regex problem.

Also not that important but return type of

System.getProperty("line.separator")

is String so no need to call toString().

This script outputs the number of unique values in each column of a given file. It assumes that first line of given file is header line. There is no need for defining number of fields. Simply save the script in a bash file (.sh) and provide the tab delimited file as a parameter to this script.

Code

#!/bin/bash

awk '
(NR==1){
    for(fi=1; fi<=NF; fi++)
        fname[fi]=$fi;
} 
(NR!=1){
    for(fi=1; fi<=NF; fi++) 
        arr[fname[fi]][$fi]++;
} 
END{
    for(fi=1; fi<=NF; fi++){
        out=fname[fi];
        for (item in arr[fname[fi]])
            out=out"\t"item"_"arr[fname[fi]][item];
        print(out);
    }
}
' $1

Execution Example:

bash> ./script.sh <path to tab-delimited file>

Output Example

isRef    A_15      C_42     G_24     T_18
isCar    YEA_10    NO_40    NA_50
isTv     FALSE_33  TRUE_66

You can use Edit > Column Editor... to insert text at the current and following lines. The shortcut is Alt + C.

I think it's better to use the Microsoft.VisualBasic.FileIO.TextFieldParser Class if you're working with comma separated values text files.

I don't know Java too well, but if you can't find a Split method that does that, I suggest you just make your own.

string[] mySplit(string s,string delimiter)
{
    string[] result = s.Split(delimiter);
    for(int i=0;i<result.Length-1;i++)
    {
        result[i] += delimiter; //this one would add the delimiter to each items end except the last item, 
                    //you can modify it however you want
    }
}
string[] res = mySplit(myString,myDelimiter);

Its not too elegant, but it'll do.

If stuffs is a list of strings, just this would work:

{{ stuffs|join(", ") }}

Link to join filter documentation, link to filters in general documentation.

p.s.

More reader friendly way {{ my ~ ', ' ~ string }}

Something less verbose, std and takes anything separated by a comma.

stringstream ss( "1,1,1,1, or something else ,1,1,1,0" );
vector<string> result;

while( ss.good() )
{
    string substr;
    getline( ss, substr, ',' );
    result.push_back( substr );
}

CsvHelper library is very popular in the Nuget.You worth it,man! https://github.com/JoshClose/CsvHelper/wiki/Basics

Using CsvHelper is really easy. It's default settings are setup for the most common scenarios.

Here is a little setup data.

Actors.csv:

Id,FirstName,LastName  
1,Arnold,Schwarzenegger  
2,Matt,Damon  
3,Christian,Bale

Actor.cs (custom class object that represents an actor):

public class Actor
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Reading the CSV file using CsvReader:

var csv = new CsvReader( new StreamReader( "Actors.csv" ) );

var actorsList = csv.GetRecords();

Writing to a CSV file.

using (var csv = new CsvWriter( new StreamWriter( "Actors.csv" ) )) 
{
    csv.WriteRecords( actorsList );
}

Several tips:

1. Put inserts/updates in a transaction.
2. For older versions of SQLite - Consider a less paranoid journal mode (pragma journal_mode). There is NORMAL, and then there is OFF, which can significantly increase insert speed if you're not too worried about the database possibly getting corrupted if the OS crashes. If your application crashes the data should be fine. Note that in newer versions, the OFF/MEMORY settings are not safe for application level crashes.
3. Playing with page sizes makes a difference as well (PRAGMA page_size). Having larger page sizes can make reads and writes go a bit faster as larger pages are held in memory. Note that more memory will be used for your database.
4. If you have indices, consider calling CREATE INDEX after doing all your inserts. This is significantly faster than creating the index and then doing your inserts.
5. You have to be quite careful if you have concurrent access to SQLite, as the whole database is locked when writes are done, and although multiple readers are possible, writes will be locked out. This has been improved somewhat with the addition of a WAL in newer SQLite versions.
6. Take advantage of saving space...smaller databases go faster. For instance, if you have key value pairs, try making the key an INTEGER PRIMARY KEY if possible, which will replace the implied unique row number column in the table.
7. If you are using multiple threads, you can try using the shared page cache, which will allow loaded pages to be shared between threads, which can avoid expensive I/O calls.
8. Don't use !feof(file)!

I've also asked similar questions here and here.

Well nobody answered - which is in part the fault of the question : the input string contains eleven fields (this much can be inferred) but how many tabs ? Most possibly exactly 10. Then the answer is

String s = "\t2\t\t4\t5\t6\t\t8\t\t10\t";
String[] fields = s.split("\t", -1);  // in your case s.split("\t", 11) might also do
for (int i = 0; i < fields.length; ++i) {
    if ("".equals(fields[i])) fields[i] = null;
}
System.out.println(Arrays.asList(fields));
// [null, 2, null, 4, 5, 6, null, 8, null, 10, null]
// with s.split("\t") : [null, 2, null, 4, 5, 6, null, 8, null, 10]

If the fields happen to contain tabs this won't work as expected, of course.
The -1 means : apply the pattern as many times as needed - so trailing fields (the 11th) will be preserved (as empty strings ("") if absent, which need to be turned to null explicitly).

If on the other hand there are no tabs for the missing fields - so "5\t6" is a valid input string containing the fields 5,6 only - there is no way to get the fields[] via split.

See this youtube video: BASH scripting lesson 10 working with CSV files

CSV file:

Bob Brown;Manager;16581;Main

/^\d+(?:, ?\d+)*$/

At some point, you're trying to convert an nvarchar column to a varchar column (or vice-versa).

Moreover, why is everything (supposedly) nvarchar(max)? That's a code smell if I ever saw one. Are you aware of how SQL Server stores those columns? They use pointers to where the column is stored from the actual rows, since they don't fit within the 8k pages.

What if you want your parts to contain commas? Well, quote them. And then what about the quotes? Well, double them up. In other words:

part1,"part2,with a comma and a quote "" in it",part3

PHP provides the https://php.net/str_getcsv function to parse a string as if it were a line in a CSV file which can be used with the above line instead of explode:

print_r(str_getcsv('part1,"part2,with a comma and a quote "" in it",part3'));
Array
(
    [0] => part1
    [1] => part2,with a comma and a quote " in it
    [2] => part3
)

This solution detects these 4 cases

complete class is at

https://github.com/pedro-vicente/csv-parser

1,field 2,field 3,
1,field 2,"field 3 quoted, with separator",
1,field 2,"field 3
with newline",
1,field 2,"field 3
with newline and separator,",

It reads the file character by character, and reads 1 row at a time to a vector (of strings), therefore suitable for very large files.

Usage is

Iterate until an empty row is returned (end of file). A row is a vector where each entry is a CSV column.

read_csv_t csv;
csv.open("../test.csv");
std::vector<std::string> row;
while (true)
{
  row = csv.read_row();
  if (row.size() == 0)
  {
    break;
  }
}

the class declaration

class read_csv_t
{
public:
  read_csv_t();
  int open(const std::string &file_name);
  std::vector<std::string> read_row();
private:
  std::ifstream m_ifs;
};

the implementation

std::vector<std::string> read_csv_t::read_row()
{
  bool quote_mode = false;
  std::vector<std::string> row;
  std::string column;
  char c;
  while (m_ifs.get(c))
  {
    switch (c)
    {
      /////////////////////////////////////////////////////////////////////////////////////////////////////
      //separator ',' detected. 
      //in quote mode add character to column
      //push column if not in quote mode
      /////////////////////////////////////////////////////////////////////////////////////////////////////

    case ',':
      if (quote_mode == true)
      {
        column += c;
      }
      else
      {
        row.push_back(column);
        column.clear();
      }
      break;

      /////////////////////////////////////////////////////////////////////////////////////////////////////
      //quote '"' detected. 
      //toggle quote mode
      /////////////////////////////////////////////////////////////////////////////////////////////////////

    case '"':
      quote_mode = !quote_mode;
      break;

      /////////////////////////////////////////////////////////////////////////////////////////////////////
      //line end detected
      //in quote mode add character to column
      //return row if not in quote mode
      /////////////////////////////////////////////////////////////////////////////////////////////////////

    case '\n':
    case '\r':
      if (quote_mode == true)
      {
        column += c;
      }
      else
      {
        return row;
      }
      break;

      /////////////////////////////////////////////////////////////////////////////////////////////////////
      //default, add character to column
      /////////////////////////////////////////////////////////////////////////////////////////////////////

    default:
      column += c;
      break;
    }
  }

  //return empty vector if end of file detected 
  m_ifs.close();
  std::vector<std::string> v;
  return v;
}

Using bash, this will do the trick:

$ sort -t$'\t' -k3 -nr file.txt

Notice the dollar sign in front of the single-quoted string. You can read about it in the ANSI-C Quoting sections of the bash man page.

For String Integer without space as String

arr = "12345"

arr.split('')

output: ["1","2","3","4","5"]

For String Integer with space as String

arr = "1 2 3 4 5"

arr.split(' ')

output: ["1","2","3","4","5"]

For String Integer without space as Integer

arr = "12345"

arr.split('').map(&:to_i)

output: [1,2,3,4,5]

For String

arr = "abc"

arr.split('')

output: ["a","b","c"]

Explanation:

1. arr -> string which you're going to perform any action.
2. split() -> is an method, which split the input and store it as array.
3. '' or ' ' or ',' -> is an value, which is needed to be removed from given string.

If you can turn your datatable into an IEnumerable this should work for you...

    Response.Clear();
    Response.Buffer = true;

    Response.AddHeader("content-disposition", "attachment;filename=FileName.csv");
    Response.Charset = "";
    Response.ContentType = "application/text";
    Response.Output.Write(ExampleClass.ConvertToCSV(GetListOfObject(), typeof(object)));
    Response.Flush();
    Response.End();



public static string ConvertToCSV(IEnumerable col, Type type)
        {
            StringBuilder sb = new StringBuilder();
            StringBuilder header = new StringBuilder();

            // Gets all  properies of the class
            PropertyInfo[] pi = type.GetProperties();

            // Create CSV header using the classes properties
            foreach (PropertyInfo p in pi)
            {
                header.Append(p.Name + ",");
            }

            sb.AppendLine(header.ToString().Remove(header.Length));

            foreach (object t in col)
            {
                StringBuilder body = new StringBuilder();

                // Create new item
                foreach (PropertyInfo p in pi)
                {
                    object o = p.GetValue(t, null);
                    body.Append(o.ToString() + ",");
                }

                sb.AppendLine(body.ToString().Remove(body.Length));
            }
            return sb.ToString();
        }

Don't use a function that loops to split a string!, my function below will split a string very fast, with no looping!

Before you use my function, you need to set up a "helper" table, you only need to do this one time per database:

CREATE TABLE Numbers
(Number int  NOT NULL,
    CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
DECLARE @x int
SET @x=0
WHILE @x<8000
BEGIN
    SET @x=@x+1
    INSERT INTO Numbers VALUES (@x)
END

use this function to split your string, which does not loop and is very fast:

CREATE FUNCTION [dbo].[FN_ListToTable]
(
     @SplitOn              char(1)              --REQUIRED, the character to split the @List string on
    ,@List                 varchar(8000)        --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
    ListValue varchar(500)
)
AS
BEGIN

/**
Takes the given @List string and splits it apart based on the given @SplitOn character.
A table is returned, one row per split item, with a column name "ListValue".
This function workes for fixed or variable lenght items.
Empty and null items will not be included in the results set.


Returns a table, one row per item in the list, with a column name "ListValue"

EXAMPLE:
----------
SELECT * FROM dbo.FN_ListToTable(',','1,12,123,1234,54321,6,A,*,|||,,,,B')

    returns:
        ListValue  
        -----------
        1
        12
        123
        1234
        54321
        6
        A
        *
        |||
        B

        (10 row(s) affected)

**/



----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
INSERT INTO @ParsedList
        (ListValue)
    SELECT
        ListValue
        FROM (SELECT
                  LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(@SplitOn, List2, number+1)-number - 1))) AS ListValue
                  FROM (
                           SELECT @SplitOn + @List + @SplitOn AS List2
                       ) AS dt
                      INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
                  WHERE SUBSTRING(List2, number, 1) = @SplitOn
             ) dt2
        WHERE ListValue IS NOT NULL AND ListValue!=''



RETURN

END --Function FN_ListToTable

you can use this function as a table in a join:

SELECT
    Col1, COl2, Col3...
    FROM  YourTable
        INNER JOIN FN_ListToTable(',',@YourString) s ON  YourTable.ID = s.ListValue

Here is your example:

Select * from sometable where tableid in(SELECT ListValue FROM dbo.FN_ListToTable(',',@Ids) s)

There has been an open feature request since at least 2009. The long and short of it is that it will part of the functionality of JDK 8's java.util.StringJoiner class. http://download.java.net/lambda/b81/docs/api/java/util/StringJoiner.html

Here is the Oracle issue if you are interested. http://bugs.sun.com/view_bug.do?bug_id=5015163

Here is an example of the new JDK 8 StringJoiner on an array of String

String[] a = new String[]{"first","second","third"};
StringJoiner sj = new StringJoiner(",");
for(String s:a) sj.add(s);
System.out.println(sj); //first,second,third

A utility method in String makes this even simpler:

String s = String.join(",", stringArray);

I am tempted to squeeze in my favourite solution. The resulting table will consist of 2 columns: PosIdx for position of the found integer; and Value in integer.

create function FnSplitToTableInt
(
    @param nvarchar(4000)
)
returns table as
return
    with Numbers(Number) as 
    (
        select 1 
        union all 
        select Number + 1 from Numbers where Number < 4000
    ),
    Found as
    (
        select 
            Number as PosIdx,
            convert(int, ltrim(rtrim(convert(nvarchar(4000), 
                substring(@param, Number, 
                charindex(N',' collate Latin1_General_BIN, 
                @param + N',', Number) - Number))))) as Value
        from   
            Numbers 
        where  
            Number <= len(@param)
        and substring(N',' + @param, Number, 1) = N',' collate Latin1_General_BIN
    )
    select 
        PosIdx, 
        case when isnumeric(Value) = 1 
            then convert(int, Value) 
            else convert(int, null) end as Value 
    from 
        Found

It works by using recursive CTE as the list of positions, from 1 to 100 by default. If you need to work with string longer than 100, simply call this function using 'option (maxrecursion 4000)' like the following:

select * from FnSplitToTableInt
(
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' + 
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0'
) 
option (maxrecursion 4000)

for line in file('/tmp/foo'):
    print line.strip('\n')

I've resolved this kind of problem with a regular expression pattern. They tend to be slower than regular queries but it's an easy way to retrieve data in a comma-delimited query column

SELECT * 
FROM `TABLE`
WHERE `field` REGEXP ',?[SEARCHED-VALUE],?';

the greedy question mark helps to search at the beggining or the end of the string.

Hope that helps for anyone in the future

Here is a simple way without stragg or creating a function.

create table countries ( country_name varchar2 (100));

insert into countries values ('Albania');

insert into countries values ('Andorra');

insert into countries values ('Antigua');


SELECT SUBSTR (SYS_CONNECT_BY_PATH (country_name , ','), 2) csv
      FROM (SELECT country_name , ROW_NUMBER () OVER (ORDER BY country_name ) rn,
                   COUNT (*) OVER () cnt
              FROM countries)
     WHERE rn = cnt
START WITH rn = 1
CONNECT BY rn = PRIOR rn + 1;

CSV                                                                             
--------------------------
Albania,Andorra,Antigua                                                         

1 row selected.

As others have mentioned, if you are on 11g R2 or greater, you can now use listagg which is much simpler.

select listagg(country_name,', ') within group(order by country_name) csv
  from countries;

CSV                                                                             
--------------------------
Albania, Andorra, Antigua

1 row selected.

Use java.beans.XMLDecoder, part of core Java SE since 1.4.

XMLDecoder input = new XMLDecoder(new FileInputStream("some/path.xml"));
MyConfig config = (MyConfig) input.readObject();
input.close();

It's easy to write the configuration files by hand, or use the corresponding XMLEncoder with some setup to write new objects at run-time.

Put the values in a temporary table and then do a select where id in (select id from temptable)

I use this function (SQL Server 2005 and above).

create function [dbo].[Split]
(
    @string nvarchar(4000),
    @delimiter nvarchar(10)
)
returns @table table
(
    [Value] nvarchar(4000)
)
begin
    declare @nextString nvarchar(4000)
    declare @pos int, @nextPos int

    set @nextString = ''
    set @string = @string + @delimiter

    set @pos = charindex(@delimiter, @string)
    set @nextPos = 1
    while (@pos <> 0)
    begin
        set @nextString = substring(@string, 1, @pos - 1)

        insert into @table
        (
            [Value]
        )
        values
        (
            @nextString
        )

        set @string = substring(@string, @pos + len(@delimiter), len(@string))
        set @nextPos = @pos
        set @pos = charindex(@delimiter, @string)
    end
    return
end

The solutions so far are all quite complicated. The idiomatic solution should doubtless be:

String.Join(",", x.Cast(Of String)().ToArray())

There's no need for fancy acrobatics in new framework versions. Supposing a not-so-modern version, the following would be easiest:

Console.WriteLine(String.Join(",", CType(x.ToArray(GetType(String)), String())))

mspmsp's second solution is a nice approach as well but it's not working because it misses the AddressOf keyword. Also, Convert.ToString is rather inefficient (lots of unnecessary internal evaluations) and the Convert class is generally not very cleanly designed. I tend to avoid it, especially since it's completely redundant.

Your question is a bit vague, but I suppose UPSERT could be considered a design pattern. For languages that don't implement MERGE, a number of alternatives to solve the problem (if a suitable rows exists, UPDATE; else INSERT) exist.

If you're using Eclipse Collections, you can use makeString() or appendString().

makeString() returns a String representation, similar to toString().

It has three forms

• makeString(start, separator, end)
• makeString(separator) defaults start and end to empty strings
• makeString() defaults the separator to ", " (comma and space)

Code example:

MutableList<Integer> list = FastList.newListWith(1, 2, 3);
assertEquals("[1/2/3]", list.makeString("[", "/", "]"));
assertEquals("1/2/3", list.makeString("/"));
assertEquals("1, 2, 3", list.makeString());
assertEquals(list.toString(), list.makeString("[", ", ", "]"));

appendString() is similar to makeString(), but it appends to an Appendable (like StringBuilder) and is void. It has the same three forms, with an additional first argument, the Appendable.

MutableList<Integer> list = FastList.newListWith(1, 2, 3);
Appendable appendable = new StringBuilder();
list.appendString(appendable, "[", "/", "]");
assertEquals("[1/2/3]", appendable.toString());

If you can't convert your collection to an Eclipse Collections type, just adapt it with the relevant adapter.

List<Object> list = ...;
ListAdapter.adapt(list).makeString(",");

Note: I am a committer for Eclipse collections.

You could use XML.

E.g.

declare @xmlstring as  varchar(100) 
set @xmlstring = '<args><arg value="42" /><arg2>-1</arg2></args>' 

declare @docid int 

exec sp_xml_preparedocument @docid output, @xmlstring

select  [id],parentid,nodetype,localname,[text]
from    openxml(@docid, '/args', 1) 

The command sp_xml_preparedocument is built in.

This would produce the output:

id  parentid    nodetype    localname   text
0   NULL        1           args        NULL
2   0           1           arg         NULL
3   2           2           value       NULL
5   3           3           #text       42
4   0           1           arg2        NULL
6   4           3           #text       -1

which has all (more?) of what you you need.

This is what I used for Excel 2003:

Dictionary<string, string> props = new Dictionary<string, string>();
props["Provider"] = "Microsoft.Jet.OLEDB.4.0";
props["Data Source"] = repFile;
props["Extended Properties"] = "Excel 8.0";

StringBuilder sb = new StringBuilder();
foreach (KeyValuePair<string, string> prop in props)
{
    sb.Append(prop.Key);
    sb.Append('=');
    sb.Append(prop.Value);
    sb.Append(';');
}
string properties = sb.ToString();

using (OleDbConnection conn = new OleDbConnection(properties))
{
    conn.Open();
    DataSet ds = new DataSet();
    string columns = String.Join(",", columnNames.ToArray());
    using (OleDbDataAdapter da = new OleDbDataAdapter(
        "SELECT " + columns + " FROM [" + worksheet + "$]", conn))
    {
        DataTable dt = new DataTable(tableName);
        da.Fill(dt);
        ds.Tables.Add(dt);
    }
}

I don't belive there's a way to do it within one query, but you can play tricks like this with a temporary variable:

declare @s varchar(max)
set @s = ''
select @s = @s + City + ',' from Locations

select @s

It's definitely less code than walking over a cursor, and probably more efficient.

For my Raspberry Pi 3B model it was

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

Assuming a modern release, find -newermt is powerful:

find -newermt '10 minutes ago' ## other units work too, see `Date input formats`

or, if you want to specify a time_t (seconds since epoch):

find -newermt @1568670245

For reference, -newermt is not directly listed in the man page for find. Instead, it is shown as -newerXY, where XY are placeholders for mt. Other replacements are legal, but not applicable for this solution.

From man find -newerXY:

Time specifications are interpreted as for the argument to the -d option of GNU date.

So the following are equivalent to the initial example:

find -newermt "$(date '+%Y-%m-%d %H:%M:%S' -d '10 minutes ago')" ## long form using 'date'
find -newermt "@$(date +%s -d '10 minutes ago')" ## short form using 'date' -- notice '@'

The date -d (and find -newermt) arguments are quite flexible, but the documentation is obscure. Here's one source that seems to be on point: Date input formats

As of May 2017, multiple FROMs can be used in a single Dockerfile.
See "Builder pattern vs. Multi-stage builds in Docker" (by Alex Ellis) and PR 31257 by Tõnis Tiigi.

The general syntax involves adding FROM additional times within your Dockerfile - whichever is the last FROM statement is the final base image. To copy artifacts and outputs from intermediate images use COPY --from=<base_image_number>.

FROM golang:1.7.3 as builder
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v golang.org/x/net/html  
COPY app.go    .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .

FROM alpine:latest  
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /go/src/github.com/alexellis/href-counter/app    .
CMD ["./app"]  

The result would be two images, one for building, one with just the resulting app (much, much smaller)

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

multi               latest              bcbbf69a9b59        6 minutes ago       10.3MB  
golang              1.7.3               ef15416724f6        4 months ago        672MB  

what is a base image?

A set of files, plus EXPOSE'd ports, ENTRYPOINT and CMD.
You can add files and build a new image based on that base image, with a new Dockerfile starting with a FROM directive: the image mentioned after FROM is "the base image" for your new image.

does it mean that if I declare neo4j/neo4j in a FROM directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?

Only if you don't overwrite CMD and ENTRYPOINT.
But the image in itself is enough: you would use a FROM neo4j/neo4j if you had to add files related to neo4j for your particular usage of neo4j.

this issue was driving me insane until i found this post which said to do

brew upgrade python3 

(not using pycharm, using sublime)

Error when importing ssl in Python 3.7.4 on macOS 10.14.6

Expand your one liner into multiple lines. Then it becomes easy:

f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])

parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

Check this documentation for more informations.

I've found two older scripts that use an indefinite or even a specific string to split. As an approach, these are always helpful.

You can use

(get-item $scriptPath).Directoryname

to get the string path or if you want the Directory type use:

(get-item $scriptPath).Directory

Using generics (as in the above answers) is your best bet here. I've just double checked and:

test.put("test", arraylistone); 
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");

will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.

If you only want to change the route for picture.php then adding rewrite rule in .htaccess will serve your needs, but, if you want the URL rewriting as in Wordpress then PHP is the way. Here is simple example to begin with.

Folder structure

There are two files that are needed in the root folder, .htaccess and index.php, and it would be good to place the rest of the .php files in separate folder, like inc/.

root/
  inc/
  .htaccess
  index.php

.htaccess

RewriteEngine On
RewriteRule ^inc/.*$ index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

This file has four directives:

1. RewriteEngine - enable the rewriting engine
2. RewriteRule - deny access to all files in inc/ folder, redirect any call to that folder to index.php
3. RewriteCond - allow direct access to all other files ( like images, css or scripts )
4. RewriteRule - redirect anything else to index.php

index.php

Because everything is now redirected to index.php, there will be determined if the url is correct, all parameters are present, and if the type of parameters are correct.

To test the url we need to have a set of rules, and the best tool for that is a regular expression. By using regular expressions we will kill two flies with one blow. Url, to pass this test must have all the required parameters that are tested on allowed characters. Here are some examples of rules.

$rules = array( 
    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'
);

Next is to prepare the request uri.

$uri = rtrim( dirname($_SERVER["SCRIPT_NAME"]), '/' );
$uri = '/' . trim( str_replace( $uri, '', $_SERVER['REQUEST_URI'] ), '/' );
$uri = urldecode( $uri );

Now that we have the request uri, the final step is to test uri on regular expression rules.

foreach ( $rules as $action => $rule ) {
    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
    }
}

Successful match will, since we use named subpatterns in regex, fill the $params array almost the same as PHP fills the $_GET array. However, when using a dynamic url, $_GET array is populated without any checks of the parameters.

    /picture/some+text/51

    Array
    (
        [0] => /picture/some text/51
        [text] => some text
        [1] => some text
        [id] => 51
        [2] => 51
    )

    picture.php?text=some+text&id=51

    Array
    (
        [text] => some text
        [id] => 51
    )

These few lines of code and a basic knowing of regular expressions is enough to start building a solid routing system.

Complete source

define( 'INCLUDE_DIR', dirname( __FILE__ ) . '/inc/' );

$rules = array( 
    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'
);

$uri = rtrim( dirname($_SERVER["SCRIPT_NAME"]), '/' );
$uri = '/' . trim( str_replace( $uri, '', $_SERVER['REQUEST_URI'] ), '/' );
$uri = urldecode( $uri );

foreach ( $rules as $action => $rule ) {
    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
        include( INCLUDE_DIR . $action . '.php' );

        // exit to avoid the 404 message 
        exit();
    }
}

// nothing is found so handle the 404 error
include( INCLUDE_DIR . '404.php' );

Method np.argpartition only returns the k largest indices, performs a local sort, and is faster than np.argsort(performing a full sort) when array is quite large. But the returned indices are NOT in ascending/descending order. Let's say with an example:

We can see that if you want a strict ascending order top k indices, np.argpartition won't return what you want.

Apart from doing a sort manually after np.argpartition, my solution is to use PyTorch, torch.topk, a tool for neural network construction, providing NumPy-like APIs with both CPU and GPU support. It's as fast as NumPy with MKL, and offers a GPU boost if you need large matrix/vector calculations.

Strict ascend/descend top k indices code will be:

Note that torch.topk accepts a torch tensor, and returns both top k values and top k indices in type torch.Tensor. Similar with np, torch.topk also accepts an axis argument so that you can handle multi-dimensional arrays/tensors.

If you use maven try to add in the pom.xml

<properties>
    ...
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
    ...
</properties>

Otherwise try to change the compiler version.

Rather than relying on errors, you can query INFORMATION_SCHEMA.TABLES to see if the table exists. If there's a record, it exists. If there's no record, it doesn't exist.

You could try this:

def iterable(a):
    try:
        (x for x in a)
        return True
    except TypeError:
        return False

If we can make a generator that iterates over it (but never use the generator so it doesn't take up space), it's iterable. Seems like a "duh" kind of thing. Why do you need to determine if a variable is iterable in the first place?

CODE:

function getUniqueDataCount(objArr, propName) {
        var data = [];
        objArr.forEach(function (d, index) {
            if (d[propName]) {
                data.push(d[propName]);
            }
        });

        var uniqueList = [...new Set(data)];

        var dataSet = {};
        for (var i=0; i < uniqueList.length; i++) {
            dataSet[uniqueList[i]] = data.filter(x => x == uniqueList[i]).length;
        }
        
        return dataSet;
    }

Snippet

var data= [
          {a:'you',b:'b',c:'c',d:'c'},
          {a: 'you', b: 'b', c: 'c', d:'c'},
          {a: 'them', b: 'b', c: 'c', d:'c'},
          {a: 'them', b: 'b', c: 'c', d:'c'},
          {a: 'okay', b: 'b', c: 'c', d:'c'},
          {a: 'okay', b: 'b', c: 'c', d:'c'},
          ];
          
  console.log(getUniqueDataCount(data, 'a'));       
  
  function getUniqueDataCount(objArr, propName) {
        var data = [];
        objArr.forEach(function (d, index) {
            if (d[propName]) {
                data.push(d[propName]);
            }
        });

        var uniqueList = [...new Set(data)];

        var dataSet = {};
        for (var i=0; i < uniqueList.length; i++) {
            dataSet[uniqueList[i]] = data.filter(x => x == uniqueList[i]).length;
        }

        return dataSet;
    }

You can try string.strip()
It worked for me! :)

For Asp.Net core you better use

<partial name="_MyPartialView" model="MyModel" />

So for example

@foreach (var item in Model)
{
   <partial name="_MyItemView" model="item" />
}

If anyone is coming here looking for an answer that utilizes iframe here it is

<iframe srcdoc="<html><body>your-html-here</body></html>" />

https://caniuse.com/iframe-srcdoc

There is nothing wrong with your code. It should list all of the files and directories directly contained by the nominated directory.

The problem is most likely one of the following:

• The "." directory is not what you expect it to be. The "." pathname actually means the "current directory" or "working directory" for the JVM. You can verify what directory "." actually is by printing out dir.getCanonicalPath().

• You are misunderstanding what dir.listFiles() returns. It doesn't return all objects in the tree beneath dir. It only returns objects (files, directories, symlinks, etc) that are directly in dir.

The ".classpath" file suggests that you are looking at an Eclipse project directory, and Eclipse projects are normally configured with the Java files in a subdirectory such as "./src". I wouldn't expect to see any Java source code in the "." directory.

Can anyone explain to me why src isn't the current folder?"

Assuming that you are launching an application in Eclipse, then the current folder defaults to the project directory. You can change the default current directory via one of the panels in the Launcher configuration wizard.

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

functionName() : ReturnType { ... }

Try This:

$('#datepicker').datepicker({
    endDate: new Date()
});

It will disable the future date.

In your AsyncTask add one ProgressDialog like:

private final ProgressDialog dialog = new ProgressDialog(YourActivity.this);

you can setMessage in onPreExecute() method like:

this.dialog.setMessage("Processing..."); 
this.dialog.show();

and in your onPostExecute(Void result) method dismiss your ProgressDialog.

You can try this.

Take a look at the Mockito API docs. As the linked document mentions (Point # 12) you can use any of the doThrow(),doAnswer(),doNothing(),doReturn() family of methods from Mockito framework to mock void methods.

For example,

Mockito.doThrow(new Exception()).when(instance).methodName();

or if you want to combine it with follow-up behavior,

Mockito.doThrow(new Exception()).doNothing().when(instance).methodName();

Presuming that you are looking at mocking the setter setState(String s) in the class World below is the code uses doAnswer method to mock the setState.

World mockWorld = mock(World.class); 
doAnswer(new Answer<Void>() {
    public Void answer(InvocationOnMock invocation) {
      Object[] args = invocation.getArguments();
      System.out.println("called with arguments: " + Arrays.toString(args));
      return null;
    }
}).when(mockWorld).setState(anyString());

In Ruby, the condition and the then part of an if expression must be separated by either an expression separator (i.e. ; or a newline) or the then keyword.

So, all of these would work:

if @item.rigged then 'Yes' else 'No' end

if @item.rigged; 'Yes' else 'No' end

if @item.rigged
  'Yes' else 'No' end

There is also a conditional operator in Ruby, but that is completely unnecessary. The conditional operator is needed in C, because it is an operator: in C, if is a statement and thus cannot return a value, so if you want to return a value, you need to use something which can return a value. And the only things in C that can return a value are functions and operators, and since it is impossible to make if a function in C, you need an operator.

In Ruby, however, if is an expression. In fact, everything is an expression in Ruby, so it already can return a value. There is no need for the conditional operator to even exist, let alone use it.

BTW: it is customary to name methods which are used to ask a question with a question mark at the end, like this:

@item.rigged?

This shows another problem with using the conditional operator in Ruby:

@item.rigged? ? 'Yes' : 'No'

It's simply hard to read with the multiple question marks that close to each other.

TempData will be always available until first read, once you read it its not available any more can be useful to pass quick message also to view that will be gone after first read. ViewBag Its more useful when passing quickly piece of data to the view, normally you should pass all data to the view through model , but there is cases when you model coming direct from class that is map into database like entity framework in that case you don't what to change you model to pass a new piece of data, you can stick that into the viewbag ViewData is just indexed version of ViewBag and was used before MVC3

Assuming that the *.bak file is on the same machine as the SQL Express instance it might be a permissions issue.

If you download procmon http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx you can filter on that file path, look for ACCESS_DENIED errors and if any are there you can see the account name that's failing get to access.

simply do the select:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))

The formula for this is very simple, so try this expression,

 int num = (int) rand() % (max - min) + min;  
 //Where rand() returns a random number between 0.0 and 1.0

correct syntax at command line should be

echo -n "compute sha1" | openssl sha1

otherwise you'll hash the trailing newline character as well.

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

Using Qt in Python is a really pleasant experience: http://wiki.python.org/moin/PyQt

For the quick tutorial: http://zetcode.com/tutorials/pyqt4/

The trunk directory is the directory that you're probably most familiar with, because it is used to hold the most recent changes. Your main codebase should be in trunk.

The branches directory is for holding your branches, whatever they may be.

The tags directory is basically for tagging a certain set of files. You do this for things like releases, where you want "1.0" to be these files at these revisions and "1.1" to be these files at these revisions. You usually don't modify tags once they're made. For more information on tags, see Chapter 4. Branching and Merging (in Version Control with Subversion).

I have created a generalised solution. The function below will change ids and names of cloned object. In most cases, you will need the row number so Just add "data-row-id" attribute to the object.

function renameCloneIdsAndNames( objClone ) {

    if( !objClone.attr( 'data-row-id' ) ) {
        console.error( 'Cloned object must have \'data-row-id\' attribute.' );
    }

    if( objClone.attr( 'id' ) ) {
        objClone.attr( 'id', objClone.attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );
    }

    objClone.attr( 'data-row-id', objClone.attr( 'data-row-id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );

    objClone.find( '[id]' ).each( function() {

        var strNewId = $( this ).attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } );

        $( this ).attr( 'id', strNewId );

        if( $( this ).attr( 'name' ) ) {
            var strNewName  = $( this ).attr( 'name' ).replace( /\[\d+\]/g, function( strName ) {
                strName = strName.replace( /[\[\]']+/g, '' );
                var intNumber = parseInt( strName ) + 1;
                return '[' + intNumber + ']'
            } );
            $( this ).attr( 'name', strNewName );
        }
    });

    return objClone;
}

A working bug free update to Shmili Breuer answer.

(function() {
    $( "input[type='radio'].revertible" ).click(function() {
        var $this = $( this );

        // update and remove the previous checked class
        var $prevChecked = $('input[name=' + $this.attr('name') + ']:not(:checked).checked');
            $prevChecked.removeClass('checked');

        if( $this.hasClass("checked") ) {
            $this.removeClass("checked");
            $this.prop("checked", false);
        }
        else {
            $this.addClass("checked");
        }
    });
})();

ORDER BY alters the order in which items are returned.

GROUP BY will aggregate records by the specified columns which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc).

Tip for 1 website resizing the height. But you can change to 2 websites.

Here is my code to resize an iframe with an external website. You need insert a code into the parent (with iframe code) page and in the external website as well, so, this won't work with you don't have access to edit the external website.

• local (iframe) page: just insert a code snippet
• remote (external) page: you need a "body onload" and a "div" that holds all contents. And body needs to be styled to "margin:0"

Local:

<IFRAME STYLE="width:100%;height:1px" SRC="http://www.remote-site.com/" FRAMEBORDER="no" BORDER="0" SCROLLING="no" ID="estframe"></IFRAME>

<SCRIPT>
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
  if (e.data.substring(0,3)=='frm') document.getElementById('estframe').style.height = e.data.substring(3) + 'px';
},false);
</SCRIPT>

You need this "frm" prefix to avoid problems with other embeded codes like Twitter or Facebook plugins. If you have a plain page, you can remove the "if" and the "frm" prefix on both pages (script and onload).

Remote:

You need jQuery to accomplish about "real" page height. I cannot realize how to do with pure JavaScript since you'll have problem when resize the height down (higher to lower height) using body.scrollHeight or related. For some reason, it will return always the biggest height (pre-redimensioned).

<BODY onload="parent.postMessage('frm'+$('#master').height(),'*')" STYLE="margin:0">
<SCRIPT SRC="path-to-jquery/jquery.min.js"></SCRIPT>
<DIV ID="master">
your content
</DIV>

So, parent page (iframe) has a 1px default height. The script inserts a "wait for message/event" from the iframe. When a message (post message) is received and the first 3 chars are "frm" (to avoid the mentioned problem), will get the number from 4th position and set the iframe height (style), including 'px' unit.

The external site (loaded in the iframe) will "send a message" to the parent (opener) with the "frm" and the height of the main div (in this case id "master"). The "*" in postmessage means "any source".

Hope this helps. Sorry for my english.

Problem 1:

The generated HTML you're getting is normal. Apparently it's a feature of Angular to be able to use any kind of object as value for a select. Angular does the mapping between the HTML option-value and the value in the ng-model. Also see Umur's comment in this question: How do I set the value property in AngularJS' ng-options?

Problem 2:

Make sure you're using the following ng-options:

<select ng-model="object.item" ng-options="item.id as item.name for item in list" />

And put this in your controller to select a default value:

object.item = 4

getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().hide();

hope this will help

I have just been playing around a little bit with this concept. Basically, if you are ok with potentially having a pixel or so cut off from your last character, here is a pure css and html solution:

The way this works is by absolutely positioning a div below the viewable region of a viewport. We want the div to offset up into the visible region as our content grows. If the content grows too much, our div will offset too high, so upper bound the height our content can grow.

HTML:

<div class="text-container">
  <span class="text-content">
    PUT YOUR TEXT HERE
    <div class="ellipsis">...</div> // You could even make this a pseudo-element
  </span>
</div>

CSS:

.text-container {
    position: relative;
    display: block;
    color: #838485;
    width: 24em;
    height: calc(2em + 5px); // This is the max height you want to show of the text. A little extra space is for characters that extend below the line like 'j'
    overflow: hidden;
    white-space: normal;
}

.text-content {
  word-break: break-all;
  position: relative;
  display: block;
  max-height: 3em;       // This prevents the ellipsis element from being offset too much. It should be 1 line height greater than the viewport 
}

.ellipsis {
  position: absolute;
  right: 0;
  top: calc(4em + 2px - 100%); // Offset grows inversely with content height. Initially extends below the viewport, as content grows it offsets up, and reaches a maximum due to max-height of the content
  text-align: left;
  background: white;
}

I have tested this in Chrome, FF, Safari, and IE 11.

You can check it out here: http://codepen.io/puopg/pen/vKWJwK

You might even be able to alleviate the abrupt cut off of the character with some CSS magic.

EDIT: I guess one thing that this imposes is word-break: break-all since otherwise the content would not extend to the very end of the viewport. :(

This seems to work for me.

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

Yes, using custom tags. Example in Python, making the !join tag join strings in an array:

import yaml

## define custom tag handler
def join(loader, node):
    seq = loader.construct_sequence(node)
    return ''.join([str(i) for i in seq])

## register the tag handler
yaml.add_constructor('!join', join)

## using your sample data
yaml.load("""
paths:
    root: &BASE /path/to/root/
    patha: !join [*BASE, a]
    pathb: !join [*BASE, b]
    pathc: !join [*BASE, c]
""")

Which results in:

{
    'paths': {
        'patha': '/path/to/root/a',
        'pathb': '/path/to/root/b',
        'pathc': '/path/to/root/c',
        'root': '/path/to/root/'
     }
}

The array of arguments to !join can have any number of elements of any data type, as long as they can be converted to string, so !join [*a, "/", *b, "/", *c] does what you would expect.

Try to use the rack-cors gem. And add the header field in your Ajax call.

I think it should be .....\javaw.exe". It worked for me. Thanks.

No. If such a feature existed it would be listed in this syntax illustration. (Although it's possible there is an undocumented SQL feature, or maybe there is some package that I'm not aware of.)

Minor variation of phillfri's answer which was already a variation of Geoff's answer: I added the ability to handle completely empty tables that contain no data for the Array Code.

Sub AddDataRow(tableName As String, NewData As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Iterate through the last row and populate it with the entries from values()
    If table.ListRows.Count = 0 Then 'If table is totally empty, set lastRow as first entry
        table.ListRows.Add Position:=1
        Set lastRow = table.ListRows(1).Range
    Else
        Set lastRow = table.ListRows(table.ListRows.Count).Range
    End If
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(NewData) + 1 Then lastRow.Cells(1, col) = NewData(col - 1)
    Next col
End Sub

They are likely still referenced by the project file. Make sure they are deleted using the Solution Explorer in Visual Studio - it should show them as being missing (with an exclamation mark).

Lets say your data is -

data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }

You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

Am pretty sure you can extend this logic to your specific dict.

To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.

return render_to_response('some_page.html', {'data': sorted(data.items())})

In template file:

{% for key, value in data %}
    <tr>
        <td> Key: {{ key }} </td> 
        <td> Value: {{ value }} </td>
    </tr>
{% endfor %}

Doesn't nth-child return siblings rather than children?

var $selFirst = $(".second:nth-child(1)");

will return the first element with the class '.second'.

var $selFirst = $(".selector:nth-child(1)");

should give you the first sibling of class '.selector'

System.Diagnostics.Process.Start("explorer.exe",@"c:\teste"); 

This code works fine from the VS2010 environment and opens the local folder properly, but if you host the same application in IIS and try to open then it will fail for sure.

<form onsubmit="return confirm('Are you sure?');" />

works well for forms. Form-specific question: JavaScript Form Submit - Confirm or Cancel Submission Dialog Box

In my case just add using System; solve the issue.

I had ran into this similar problem as well. In my case, my resolution is quite different. Here's my spring context xml file:

...
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd">
...

I'm not specifying any xsd version as I want spring to use the latest xsd version inside spring dependencies. The spring version my application used was spring-beans-4.3.1.RELEASE.jar:4.3.1.RELEASE and when I assembly my application into jar, all spring dependencies exist in my classpath. However, I received following error during startup of my spring application context:

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

After some hard time troubleshooting, I found the issue is due to the index.list inside the META-INF folder of my jar file. With index.list file, spring namespace handlers cannot be located to parse the spring application context xml correctly. You can read more about this spring issue SPR-5705

By removing indexing from my maven-jar-plugin, I manage to resolve the issue. Hope this will save some times for people having the same problem.

To show the value of an environment variable you use:

echo $VARIABLE

so in your case will be:

echo $JAVA_HOME

In case you don't have it setted, you can add in your .bashrc file:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")

and it will dynamically change when you update your packages.

Or try my solution: http://robau.wordpress.com/2011/08/16/unobtrusive-table-column-resize-with-jquery-as-plugin/ :)

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

after trying a lot of time...

task scheduler : powershell.exe -noexit & .\your_script.ps1

be sure to put your script in this folder : windows\system32

good luck !

My problem was solved after turning Off Windows Firewall Defender in public network as I was connected with that network.

I've been adapting my vim plugins for two years to support big enough c++ project. You can take a look at them.

They use ctags and cscsope.

For SQL Server

select *
from YourTable
where DateCol between getdate() and dateadd(d, 90, getdate())

Say you want to access the scope of the element like

<div ng-controller="hw"></div>

You could use the following in the console:

angular.element(document.querySelector('[ng-controller=hw]')).scope();

This will give you the scope at that element.

find section [MySQLi] in your php.ini and add line mysqli.default_charset = "UTF-8". Similar changes my require for section [Pdo_mysql] and [mysqlnd].

Issue seems to be specifically with MySQL version 8.0, and above solution found working with PHP Version 7.2, and solution didn't work with PHP 7.0

There's no catchall function, because there are multiple concerns to be addressed.

1. SQL Injection - Today, generally, every PHP project should be using prepared statements via PHP Data Objects (PDO) as a best practice, preventing an error from a stray quote as well as a full-featured solution against injection. It's also the most flexible & secure way to access your database.

   Check out (The only proper) PDO tutorial for pretty much everything you need to know about PDO. (Sincere thanks to top SO contributor, @YourCommonSense, for this great resource on the subject.)

2. XSS - Sanitize data on the way in...

   • HTML Purifier has been around a long time and is still actively updated. You can use it to sanitize malicious input, while still allowing a generous & configurable whitelist of tags. Works great with many WYSIWYG editors, but it might be heavy for some use cases.

   • In other instances, where we don't want to accept HTML/Javascript at all, I've found this simple function useful (and has passed multiple audits against XSS):

     /* Prevent XSS input */ function sanitizeXSS () { $_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING); $_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING); $_REQUEST = (array)$_POST + (array)$_GET + (array)$_REQUEST; }

3. XSS - Sanitize data on the way out... unless you guarantee the data was properly sanitized before you add it to your database, you'll need to sanitize it before displaying it to your user, we can leverage these useful PHP functions:

   • When you call echo or print to display user-supplied values, use htmlspecialchars unless the data was properly sanitized safe and is allowed to display HTML.
   • json_encode is a safe way to provide user-supplied values from PHP to Javascript

4. Do you call external shell commands using exec() or system() functions, or to the backtick operator? If so, in addition to SQL Injection & XSS you might have an additional concern to address, users running malicious commands on your server. You need to use escapeshellcmd if you'd like to escape the entire command OR escapeshellarg to escape individual arguments.

The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once.

In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into this category. You can move code from @BeforeClass into @Before, but your test run may take longer. Note that the code marked @BeforeClass is run as static initializer, therefore it will run before the class instance of your test fixture is created.

In JUnit 5, the tags @BeforeEach and @BeforeAll are the equivalents of @Before and @BeforeClass in JUnit 4. Their names are a bit more indicative of when they run, loosely interpreted: 'before each tests' and 'once before all tests'.

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/getYear

getYear is no longer used and has been replaced by the getFullYear method.

The getYear method returns the year minus 1900; thus:

• For years greater than or equal to 2000, the value returned by getYear is 100 or greater. For example, if the year is 2026, getYear returns 126.
• For years between and including 1900 and 1999, the value returned by getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76.
• For years less than 1900, the value returned by getYear is less than 0. For example, if the year is 1800, getYear returns -100.
• To take into account years before and after 2000, you should use getFullYear instead of getYear so that the year is specified in full.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Synchronized on the method declaration is syntactical sugar for this:

 public void addA() {
     synchronized (this) {
          a++;
     }
  }

On a static method it is syntactical sugar for this:

 ClassA {
     public static void addA() {
          synchronized(ClassA.class) {
              a++;
          }
 }

I think if the Java designers knew then what is understood now about synchronization, they would not have added the syntactical sugar, as it more often than not leads to bad implementations of concurrency.

I figure it out with a timer, hope it helps. I have used a timer from java.util.Timer and TimerTask from the same package. See below:

TimerTask task = new TimerTask() {

    @Override
    public void run() {
        System.out.println("Hello World");
    }
};

Timer timer = new Timer();
timer.schedule(task, new Date(), 3000);

As it is 2015, and deprecation of mysql_* functionality, this is a PDO-only visualization.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    // End Vault

    $b='</br>';
    try {
        $theCategory="fruit";   // value from user, hard-coded here to get one in

        $dbh = new PDO("mysql:host=$host;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        // prepared statement with named placeholders
        $stmt = $dbh->prepare("select id,foodName from foods where category=:theCat and perishable=1");
        $stmt->bindParam(':theCat', $theCategory, PDO::PARAM_STR,20);
        $stmt->execute();
        echo "rowCount() returns: ".$stmt->rowCount().$b;   // See comments below from the Manual, varies from driver to driver

        $stmt = $dbh->prepare("select count(*) as theCount from foods where category=:theCat and perishable=1");
        $stmt->bindParam(':theCat', $theCategory, PDO::PARAM_STR,20);
        $stmt->execute();
        $row=$stmt->fetch();    // fetches just one row, which is all we expect
        echo "count(*) returns: ".$row['theCount'].$b;

        $stmt = null;
        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Schema for testing

create table foods
(   id int auto_increment primary key,
    foodName varchar(100) not null,
    category varchar(20) not null,
    perishable int not null
);
insert foods (foodName,category,perishable) values 
('kiwi','fruit',1),('ground hamburger','meat',1),
('canned pears','fruit',0),('concord grapes','fruit',1);

For my implementation, I get the output of 2 for both echos above. The purpose of the above 2 strategies is to determine if your driver implementation emits the rowCount, and if not, to seek a fall-back strategy.

From the Manual on PDOStatement::rowCount:

PDOStatement::rowCount() returns the number of rows affected by a DELETE, INSERT, or UPDATE statement.

For most databases, PDOStatement::rowCount() does not return the number of rows affected by a SELECT statement. Instead, use PDO::query() to issue a SELECT COUNT(*) statement with the same predicates as your intended SELECT statement, then use PDOStatement::fetchColumn() to retrieve the number of rows that will be returned. Your application can then perform the correct action.

I found this post while I was looking for a solution to my DNN6 website. The error was

SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference

But I needed the same solution: force compability mode to IE9. So let me share with you what I did to solve this.

So, for DotNetNuke 6 users try the StyleHelper SkinObject

Worked great for me!

Try this:

$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);

http://api.cakephp.org/2.3/class-Model.html#_getDataSource

You will have to do this for each datasource if you have more than one though.

Try adding a BindingResult parameter to methods annotated with @RequestMapping which have a @ModelAttribute annotated parameters. After each @ModelAttribute parameter, Spring looks for a BindingResult in the next parameter position (order is important).

So try changing:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) 
...

To:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) 
...

You can use .get(0) as well but...you shouldn't need to do that with an element found by ID, that should always be unique. I'm hoping this is just an oversight in the example...if this is the case on your actual page, you'll need to fix it so your IDs are unique, and use a class (or another attribute) instead.

.get() (like [0]) gets the DOM element, if you want a jQuery object use .eq(0) or .first() instead :)

Just went to build.gradle and deleted the line:

implementation 'com.android.support:appcompat-v7:26.1.0'

After that, I re-synced the Gradle. Then, I pasted the line of code back, re-synced the Gradle again and it worked.

Note: While I was making this changes, I also updated all the SDK Tools that needed update.

Percent calculation that worked for me:

(new_num - old_num) / old_num * 100.0

Additionally to

openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer
openssl pkcs12 -in domain.pfx -nocerts -nodes  -out domain.key

I also generated Certificate Authority (CA) certificate:

openssl pkcs12 -in domain.pfx -out domain-ca.crt -nodes -nokeys -cacerts

And included it in Apache config file:

<VirtualHost 192.168.0.1:443>
 ...
 SSLEngine on
 SSLCertificateFile /path/to/domain.cer
 SSLCertificateKeyFile /path/to/domain.key
 SSLCACertificateFile /path/to/domain-ca.crt
 ...
</VirtualHost>

For trimming your string, Go's "strings" package have TrimSpace(), Trim() function that trims leading and trailing spaces.

Check the documentation for more information.

The steps are as follows :

1. Close WAMP (if running)
2. Navigate to WAMP\bin\php\(your version of php)\
3. Edit php.ini
4. Search for curl, uncomment extension=php_curl.dll
5. Navigate to WAMP\bin\Apache\(your version of apache)\bin\
6. Edit php.ini
7. Search for curl, uncomment extension=php_curl.dll
8. Save both
9. Restart WAMP

In case you want to split by spaces, you can just use .split():

a = 'mary had a little lamb'
z = a.split()
print z

Output:

['mary', 'had', 'a', 'little', 'lamb'] 

Just Taking Input

the_input = raw_input("Enter input: ")

And that's it.

Moreover, if you want to make a list of inputs, you can do something like:

a = []

for x in xrange(1,10):
    a.append(raw_input("Enter Data: "))

In that case, you'll be asked for data 10 times to store 9 items in a list.

Output:

Enter data: 2
Enter data: 3
Enter data: 4
Enter data: 5
Enter data: 7
Enter data: 3
Enter data: 8
Enter data: 22
Enter data: 5
>>> a
['2', '3', '4', '5', '7', '3', '8', '22', '5']

You can search that list the fundamental way with something like (after making that list):

if '2' in a:
    print "Found"

else: print "Not found."

You can replace '2' with "raw_input()" like this:

if raw_input("Search for: ") in a:
    print "Found"
else: 
    print "Not found"

Taking Raw Data From Input File via Commandline Interface

If you want to take the input from a file you feed through commandline (which is normally what you need when doing code problems for competitions, like Google Code Jam or the ACM/IBM ICPC):

Swift 4

 let image: UIImage? =  #imageLiteral(resourceName: "logo-1").withRenderingMode(.alwaysTemplate)
    topLogo.image = image
    topLogo.tintColor = UIColor.white

What you could do is also to take the next token as a String, converts this string to a char array and test that each character in the array is a digit.

I think that's correct, if you don't want to deal with the exceptions.

Use this instead:

var divID = "question-" + (i+1)

It's a fairly common problem and doesn't just happen in JavaScript. The idea is that + can represent both concatenation and addition.

Since the + operator will be handled left-to-right the decisions in your code look like this:

• "question-" + i: since "question-" is a string, we'll do concatenation, resulting in "question-1"
• "question-1" + 1: since "queston-1" is a string, we'll do concatenation, resulting in "question-11".

With "question-" + (i+1) it's different:

• since the (i+1) is in parenthesis, its value must be calculated before the first + can be applied:
  • i is numeric, 1 is numeric, so we'll do addition, resulting in 2
• "question-" + 2: since "question-" is a string, we'll do concatenation, resulting in "question-2".

KEYUP will be captured only once, upon release of the key pressed, regardless of how long will the key be held down, so if you want to capture such press only once, KEYUP is the suitable event to capture.

In case anyone else ends up here with my issue with a DB First Entity Framework setup.

Long story short, I needed to overload the Entities constructor to accept a connection string, the reason being the ability to use Asp.Net Core dependency injection container pulling the connection string from appsettings.json, rather than magically getting it from the App.config file when calling the parameterless constructor.

I forgot to add the calls to initialize my DbSets in the new overload. So the auto-generated parameter-less constructor looked something like this:

    public MyEntities()
        : base("name=MyEntity")
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

And my new overload looked like this:

    public MyEntities(string connectionString)
        : base(connectionString)
    {
    }

The solution was to add those initializers that the auto-generated code takes care of, a simple missed step:

     public MyEntities(string connectionString)
        : base(connectionString)
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

This really threw me for a loop because some calls in our Respository that used the DbContext worked fine (the ones that didn't need those initialized DBSets), and the others throw the runtime error described in the OP.

I know it's an old thread I worked with above answer and had to add:

header('Access-Control-Allow-Methods: GET, POST, PUT');

So my header looks like:

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');

And the problem was fixed.

1) The function returns a cell for a table view yes? So, the returned object is of type UITableViewCell. These are the objects that you see in the table's rows. This function basically returns a cell, for a table view. But you might ask, how the function would know what cell to return for what row, which is answered in the 2nd question

2)NSIndexPath is essentially two things-

• Your Section
• Your row

Because your table might be divided to many sections and each with its own rows, this NSIndexPath will help you identify precisely which section and which row. They are both integers. If you're a beginner, I would say try with just one section.

It is called if you implement the UITableViewDataSource protocol in your view controller. A simpler way would be to add a UITableViewController class. I strongly recommend this because it Apple has some code written for you to easily implement the functions that can describe a table. Anyway, if you choose to implement this protocol yourself, you need to create a UITableViewCell object and return it for whatever row. Have a look at its class reference to understand re-usablity because the cells that are displayed in the table view are reused again and again(this is a very efficient design btw).

As for when you have two table views, look at the method. The table view is passed to it, so you should not have a problem with respect to that.

I struggled to solve a similar problem around data table classes instead of messages. The root issue mentioned above of casting a non-generic version of the class to a derived generic version was the same.

In order to allow injection into a portable class library which did not support database libraries, I introduced a set of interface classes, with the intent that I could pass a type and get a matching generic. It ended up needing to implement a generic method.

// Interface for injection
public interface IDatabase
{
    // Original, non-functional signature:
    IDatatable<object> GetDataTable(Type dataType);

    // Functional method using a generic method:
    IDatatable<T> GetDataTable<T>();
}

And this the whole implementation using the generic method above.

The generic class that will be cast from a dictionary.

// Non-generic base class allows listing tables together
abstract class Datatable
{
    Datatable(Type storedClass)
    {
      StoredClass = storedClass;
    }

    Type StoredClass { get; private set; }
}

// Generic inheriting class
abstract class Datatable<T>: Datatable, IDatatable<T>
{
    protected Datatable()
        :base(typeof(T))
    {
    }
}

This is the class that stores the generic class and casts it to satisfy the generic method in the interface

class Database
{
    // Dictionary storing the classes using the non-generic base class
    private Dictionary<Type, Datatable> _tableDictionary;

    protected Database(List<Datatable> tables)
    {
        _tableDictionary = new Dictionary<Type, Datatable>();
        foreach (var table in tables)
        {
            _tableDictionary.Add(table.StoredClass, table);
        }
    }

    // Interface implementation, casts the generic
    public IDatatable<T> GetDataTable<T>()
    {
        Datatable table = null;

        _tableDictionary.TryGetValue(typeof(T), out table);

        return table as IDatatable<T>;
    }
}

And finally the calling of the interface method.

IDatatable<CustomerAccount> table = _database.GetDataTable<CustomerAccount>();

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

You've gotten several good answers and I'd go with the Bash builtin myself, but since you asked about sed and awk and (almost) no one else offered solutions based on them, I offer you these:

echo "USCAGoleta9311734.5021-120.1287855805" | awk '{print substr($0,0,2)}'

and

echo "USCAGoleta9311734.5021-120.1287855805" | sed 's/\(^..\).*/\1/'

The awk one ought to be fairly obvious, but here's an explanation of the sed one:

• substitute "s/"
• the group "()" of two of any characters ".." starting at the beginning of the line "^" and followed by any character "." repeated zero or more times "*" (the backslashes are needed to escape some of the special characters)
• by "/" the contents of the first (and only, in this case) group (here the backslash is a special escape referring to a matching sub-expression)
• done "/"

Use event delegation by assigning the onclick to the <ol>. Then pass the event object as the argument, and using that, grab the text from the clicked element.

function addText(event) {_x000D_
    var targ = event.target || event.srcElement;_x000D_
    document.getElementById("alltext").value += targ.textContent || targ.innerText;_x000D_
}

<textarea id="alltext"></textarea>_x000D_
_x000D_
<ol onclick="addText(event)">_x000D_
  <li>Hello</li>_x000D_
  <li>World</li>_x000D_
  <li>Earthlings</li>_x000D_
</ol>

Note that this method of passing the event object works in older IE as well as W3 compliant systems.

Add the Line before println and your array gets sorted

Arrays.sort( array );

A slightly more verbose express 4.x version but that provides directory listing, compression, caching and requests logging in a minimal number of lines

var express = require('express');
var compress = require('compression');
var directory = require('serve-index');
var morgan = require('morgan'); //logging for express

var app = express();

var oneDay = 86400000;

app.use(compress());
app.use(morgan());
app.use(express.static('filesdir', { maxAge: oneDay }));
app.use(directory('filesdir', {'icons': true}))

app.listen(process.env.PORT || 8000);

console.log("Ready To serve files !")

.equals(false) will be slower because you are calling a virtual method on an object rather than using faster syntax and rather unexpected by most of the programmers because code standards that are generally used don't really assume you should be doing that check via .equals(false) method.

Here is an alternative programming solution that may work for others who use MyISAM IF (important) you don't care if an update has happened during the middle of the queries. As we know MyISAM can cause table level locks, especially if you have an update pending which will get locked, and then other select queries behind this update get locked too.

So this method won't prevent a lock, but it will make a lot of tiny locks, so as not to hang a website for example which needs a response within a very short frame of time.

The idea here is we grab a range based on an index which is quick, then we do our match from that query only, so it's in smaller batches. Then we move down the list onto the next range and check them for our match.

Example is in Perl with a bit of pseudo code, and traverses high to low.

# object_id must be an index so it's fast
# First get the range of object_id, as it may not start from 0 to reduce empty queries later on.

my ( $first_id, $last_id ) = $db->db_query_array(
  sql => q{ SELECT MIN(object_id), MAX(object_id) FROM mytable }
);

my $keep_running = 1;
my $step_size    = 1000;
my $next_id      = $last_id;

while( $keep_running ) {

    my $sql = q{ 
SELECT object_id, created, status FROM 
    ( SELECT object_id, created, status FROM mytable AS is1 WHERE is1.object_id <= ? ORDER BY is1.object_id DESC LIMIT ? ) AS is2
WHERE status='live' ORDER BY object_id DESC 
};  

    my $sth = $db->db_query( sql => $sql, args => [ $step_size, $next_id ] );

    while( my ($object_id, $created, $status ) = $sth->fetchrow_array() ) {

        $last_id = $object_id;
        
        ## do your stuff

    }

    if( !$last_id ) {
        $next_id -= $step_size; # There weren't any matched in the range we grabbed
    } else {
        $next_id = $last_id - 1; # There were some, so we'll start from that.
    }

    $keep_running = 0 if $next_id < 1 || $next_id < $first_id;
    
}

In .NET 4.5 it's possible to bind to static properties, read more

You can use static properties as the source of a data binding. The data binding engine recognizes when the property's value changes if a static event is raised. For example, if the class SomeClass defines a static property called MyProperty, SomeClass can define a static event that is raised when the value of MyProperty changes. The static event can use either of the following signatures:

public static event EventHandler MyPropertyChanged; 
public static event EventHandler<PropertyChangedEventArgs> StaticPropertyChanged; 

Note that in the first case, the class exposes a static event named PropertyNameChanged that passes EventArgs to the event handler. In the second case, the class exposes a static event named StaticPropertyChanged that passes PropertyChangedEventArgs to the event handler. A class that implements the static property can choose to raise property-change notifications using either method.

Here is how to build a function that returns a result set that can be queried as if it were a table:

SQL> create type emp_obj is object (empno number, ename varchar2(10));
  2  /

Type created.

SQL> create type emp_tab is table of emp_obj;
  2  /

Type created.

SQL> create or replace function all_emps return emp_tab
  2  is
  3     l_emp_tab emp_tab := emp_tab();
  4     n integer := 0;
  5  begin
  6     for r in (select empno, ename from emp)
  7     loop
  8        l_emp_tab.extend;
  9        n := n + 1;
 10       l_emp_tab(n) := emp_obj(r.empno, r.ename);
 11     end loop;
 12     return l_emp_tab;
 13  end;
 14  /

Function created.

SQL> select * from table (all_emps);

You can use @@ROWCOUNT to check whether row should be inserted or updated:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'
if @@ROWCOUNT = 0
insert into table1(id, name, itemname, itemcatName, itemQty)
values('val1', 'val2', 'val3', 'val4', 'val5')

in this case if update fails, the new row will be inserted

You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat

I say this because captions are usually applied to floats.

Straight ahead equations (those written with $ ... $, $$ ... $$, begin{equation}...) are in-line objects that do not support \caption.

This can be done using the following snippet just before \begin{document}

\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}

\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
  \let\ORIGINALcaption\caption
  \def\caption{%
    \addtocounter{equation}{-1}%
    \ORIGINALcaption
  }%
  \ORGeqfloat
}

and when adding an equation use something like

\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}

For checking Strings for letters you can use regular expressions for example:

someString.matches("[A-F]");

For checking numbers and stopping the program crashing, I have a quite simple class you can find below where you can define the range of values you want. Here

    public int readInt(String prompt, int min, int max)
    {
    Scanner scan = new Scanner(System.in);

    int number = 0;

    //Run once and loop until the input is within the specified range.
    do 
    {
        //Print users message.
        System.out.printf("\n%s > ", prompt);

        //Prevent string input crashing the program.
        while (!scan.hasNextInt()) 
        {
            System.out.printf("Input doesn't match specifications. Try again.");
            System.out.printf("\n%s > ", prompt);
            scan.next(); 
        }

        //Set the number.
        number = scan.nextInt();

        //If the number is outside range print an error message.
        if (number < min || number > max)
            System.out.printf("Input doesn't match specifications. Try again.");

    } while (number < min || number > max);

    return number;
}

The essence of how it does this lies in this excerpt from Applied Numerical Analysis by Gerald Wheatley:

When your software program asks the computer to get a value of or , have you wondered how it can get the values if the most powerful functions it can compute are polynomials? It doesnt look these up in tables and interpolate! Rather, the computer approximates every function other than polynomials from some polynomial that is tailored to give the values very accurately.

A few points to mention on the above is that some algorithms do infact interpolate from a table, albeit only for the first few iterations. Also note how it mentions that computers utilise approximating polynomials without specifying which type of approximating polynomial. As others in the thread have pointed out, Chebyshev polynomials are more efficient than Taylor polynomials in this case.

Here is another solution

Set a hidden scope variable in your html then you can use it from your controller:

<span style="display:none" >{{ formValid = myForm.$valid}}</span>

Here is the full working example:

.controller('myController', function($scope) {_x000D_

  console.info('Ctrl init, no form.');_x000D_
  _x000D_
  $scope.$watch('myForm', function() {_x000D_
    console.info('myForm watch');_x000D_
    console.log($scope.formValid);_x000D_
  });_x000D_
  _x000D_
  $scope.isFormValid = function() {_x000D_
    //test the new scope variable_x000D_
    console.log('form valid?: ', $scope.formValid);_x000D_
  };_x000D_
});

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting

See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format

CHECK constraints are ignored by MySQL as explained in a miniscule comment in the docs: CREATE TABLE

The CHECK clause is parsed but ignored by all storage engines.

First I recommand you can try use print and observe the action:

for i in range(0, 5, 1):
    print i

the result:

0
1
2
3
4

You can understand the function principle. In fact, range scan range is from 0 to 5-1. It equals 0 <= i < 5

When you really understand for-loop in python, I think its time we get back to business. Let's focus your problem.

You want to use a DECREMENT for-loop in python. I suggest a for-loop tutorial for example.

for i in range(5, 0, -1):
    print i

the result:

5
4
3
2
1

Thus it can be seen, it equals 5 >= i > 0

You want to implement your java code in python:

for (int index = last-1; index >= posn; index--)

It should code this:

for i in range(last-1, posn-1, -1)

There is also the env_inst_info admin view. As with CanSpice I can only vouch for LUW, but there should at least be a similar view available for Z/OS.

SELECT * FROM SYSIBMADM.ENV_INST_INFO

I'm not sure if this will work for your actual use, but it works in your test case - updated at http://jsfiddle.net/sTD8y/27/ .

I just made it so that the built-in revert is only used if the item has not been dropped before. If it has been dropped, the revert is done manually. You could adjust this to animate to some calculated offset by checking the actual CSS properties, but I'll let you play with that because a lot of it depends on the CSS of the draggable and it's surrounding DOM structure.

$(function() {
    $("#draggable").draggable({
        revert:  function(dropped) {
             var $draggable = $(this),
                 hasBeenDroppedBefore = $draggable.data('hasBeenDropped'),
                 wasJustDropped = dropped && dropped[0].id == "droppable";
             if(wasJustDropped) {
                 // don't revert, it's in the droppable
                 return false;
             } else {
                 if (hasBeenDroppedBefore) {
                     // don't rely on the built in revert, do it yourself
                     $draggable.animate({ top: 0, left: 0 }, 'slow');
                     return false;
                 } else {
                     // just let the built in revert work, although really, you could animate to 0,0 here as well
                     return true;
                 }
             }
        }
    });

    $("#droppable").droppable({
        activeClass: 'ui-state-hover',
        hoverClass: 'ui-state-active',
        drop: function(event, ui) {
            $(this).addClass('ui-state-highlight').find('p').html('Dropped!');
            $(ui.draggable).data('hasBeenDropped', true);
        }
    });
});

You can use split() to get string array from comma separated string. If you iterate and perform mathematical operation on element of string array then that element will be treated as number by run-time cast but still you have string array. To convert comma separated string int array see the edit.

arr = strVale.split(',');

Live Demo

var strVale = "130,235,342,124";
arr = strVale.split(',');
for(i=0; i < arr.length; i++)
    console.log(arr[i] + " * 2 = " + (arr[i])*2);

Output

130 * 2 = 260
235 * 2 = 470
342 * 2 = 684
124 * 2 = 248

Edit, Comma separated string to int Array In the above example the string are casted to numbers in expression but to get the int array from string array you need to convert it to number.

var strVale = "130,235,342,124";
var strArr = strVale.split(',');
var intArr = [];
for(i=0; i < strArr.length; i++)
   intArr.push(parseInt(strArr[i]));

If the soft methods via gradle file / "Invalidate caches" and the other IDE tools do not work, use the hard way:

1. Exit Android Studio
2. Navigate in your project to the .idea folder
3. Just Rename the libraries folder
4. Restart Android Studio. It should now recreate the libraries folder and work again.

I hate to add yet another answer to a long thread, but I found a solution that enables recursive reloading of submodules on %run() that others might find useful (I have anyway)

del the submodule you wish to reload on run from sys.modules in iPython:

In[1]: from sys import modules
In[2]: del modules["mymodule.mysubmodule"] # tab completion can be used like mymodule.<tab>!

Now your script will recursively reload this submodule:

In[3]: %run myscript.py

What about $("ul#list li:not(.active)")?

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

you want these four lines of code in your Run.bat:

@echo off          //this makes it so you have an empty cmd window on startup
javac Main.java    //this compiles the .java into a .class
java Main          // this runs the .class file
pause              //this prevents the window from instantly closing after program end

Let's say you have an associative array like this:

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => array('x'=>123)
);

In the first iteration : $key="one" and $value=1.

Sometimes you need this key ,if you want only the value , you can avoid using it.

In the last iteration : $key='seventeen' and $value = array('x'=>123) so to get value of the first element in this array value, you need a key, x in this case: $value['x'] =123.

If you make sure that this is the first event handler work, something like this might do the trick:

$('*').click(function(event) {
    if (this === event.target) { // only fire this handler on the original element
        alert('clicked');
    }
});

Note that, if you have lots of elements in your page, this will be Really Very Slow, and it won't work for anything added dynamically.

It is also possible to use the new button attribute called formtarget that was introduced with HTML5.

<form>
  <input type="submit" formtarget="_blank"/>
</form>

Is the name of your service class really IService (on the Service namespace)? What you probably had originally was a mismatch in the name of the service class in the name attribute of the <service> element.

When a and b are 1-dimensional sequences, numpy.cov(a,b)[0][1] is equivalent to your cov(a,b).

The 2x2 array returned by np.cov(a,b) has elements equal to

cov(a,a)  cov(a,b)

cov(a,b)  cov(b,b)

(where, again, cov is the function you defined above.)

I suspect the problem is that you've put the "-D" after the -jar. Try this:

java -Dtest="true" -jar myApplication.jar

From the command line help:

java [-options] -jar jarfile [args...]

In other words, the way you've got it at the moment will treat -Dtest="true" as one of the arguments to pass to main instead of as a JVM argument.

(You should probably also drop the quotes, but it may well work anyway - it probably depends on your shell.)

I had a bad php.ini configuration. Verify the path and the certificate validity...

This is almost certainly a bad idea. Certainly if the ordinal is de-facto persisted (e.g. because someone has bookmarked the URL) - it means that you must always preserve the enum ordering in future, which may not be obvious to code maintainers down the line.

Why not encode the enum using myEnumValue.name() (and decode via ReportTypeEnum.valueOf(s)) instead?

Why not use reduce so that we can take colspan into account? :)

function getColumns(table) {
    var cellsArray = [];
    var cells = table.rows[0].cells;

    // Cast the cells to an array
    // (there are *cooler* ways of doing this, but this is the fastest by far)
    // Taken from https://stackoverflow.com/a/15144269/6424295
    for(var i=-1, l=cells.length; ++i!==l; cellsArray[i]=cells[i]);

    return cellsArray.reduce(
        (cols, cell) =>
            // Check if the cell is visible and add it / ignore it
            (cell.offsetParent !== null) ? cols += cell.colSpan : cols,
        0
    );
}

It is pretty obvious that array[10] is faster than array.get(10), as the later internally does the same call, but adds the overhead for the function call plus additional checks.

Modern JITs however will optimize this to a degree, that you rarely have to worry about this, unless you have a very performance critical application and this has been measured to be your bottleneck.

Use ElasticDump

1) yum install epel-release

2) yum install nodejs

3) yum install npm

4) npm install elasticdump

5) cd node_modules/elasticdump/bin

6)

./elasticdump \

Convert the Special characters to apostrophe,

Data  <- gsub("[^0-9A-Za-z///' ]","'" , Data ,ignore.case = TRUE)

Below code it to remove extra ''' apostrophe

Data <- gsub("''","" , Data ,ignore.case = TRUE)

Use gsub(..) function for replacing the special character with apostrophe

To get the value of a drop-down (select) element, just use val().

$('._someDropDown').live('change', function(e) {
  alert($(this).val());
});

If you want to the text of the selected option, using this:

$('._someDropDown').live('change', function(e) {
  alert($('[value=' + $(this).val() + ']', this).text());
});

These all are ways:

String imageUri = "drawable://" + R.drawable.image;

Other ways I tested

Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");

String path = path.toString();
String path = otherPath .toString();

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"

I wrote a little library that handles generic trees. It's much more lightweight than the swing stuff. I also have a maven project for it.

The base difference that which already everyone mentioned is that one is heavy weight and other is light weight. Let me explain, basically what the term heavy weight means is that when you're using the awt components the native code used for getting the view component is generated by the Operating System, thats why it the look and feel changes from OS to OS. Where as in swing components its the responsibility of JVM to generate the view for the components. Another statement which i saw is that swing is MVC based and awt is not.

If the MIME TYPE is already having the .woff and .woff2 file types and still it's giving HTTP-404 error, check the request filtering. If this is restrictive, add these file types these with allow to serve and it shall work. Check it out!

As Mitch mentioned, backing data up is the best method.

However, it maybe possible to extract the lost data partially depending on the situation or DB server used. For most part, you are out of luck if you don't have any backup.

If you really need it...

html { overflow-y: hidden; }

Sometimes you must change the name (or check to get it automatically from compiler).

Example:

Filename = amp2-rot.png

It is not working as:

PictureBoxName.Image = resources.GetObject("amp2-rot.png")

It works, just as amp2_rot for me:

 PictureBox_L1.Image = My.Resources.Resource.amp2_rot

logger logs to syslog facilities. If you want the message to go to a particular file you have to modify the syslog configuration accordingly. You could add a line like this:

local7.*   -/var/log/mycustomlog

and restart syslog. Then you can log like this:

logger -p local7.info "information message"
logger -p local7.err "error message"

and the messages will appear in the desired logfile with the correct log level.

Without making changes to the syslog configuration you could use logger like this:

logger -s "foo bar" >> /var/log/mycustomlog

That would instruct logger to print the message to STDERR as well (in addition to logging it to syslog), so you could redirect STDERR to a file. However, it would be utterly pointless, because the message is already logged via syslog anyway (with the default priority user.notice).

Just to summarize, here's a complete answer, that worked for me.

My problem was that when I used

[NSString stringWithUTF8String:(char *)data.bytes];

The string I got was unpredictable: Around 70% it did contain the expected value, but too often it resulted with Null or even worse: garbaged at the end of the string.

After some digging I switched to

[[NSString alloc] initWithBytes:(char *)data.bytes length:data.length encoding:NSUTF8StringEncoding];

And got the expected result every time.

Or you can use https://tolocalhost.com/ and configure how it should redirect a callback to your local site. You can specify the hostname (if different from localhost, i.e. yourapp.local and the port number). For development purposes only.

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

You should try to avoid using GC.Collect() since its very expensive. Here is an example:

        public void ClearFrame(ulong timeStamp)
    {
        if (RecordSet.Count <= 0) return;
        if (Limit == false)
        {
            var seconds = (timeStamp - RecordSet[0].TimeStamp)/1000;
            if (seconds <= _preFramesTime) return;
            Limit = true;
            do
            {
                RecordSet.Remove(RecordSet[0]);
            } while (((timeStamp - RecordSet[0].TimeStamp) / 1000) > _preFramesTime);
        }
        else
        {
            RecordSet.Remove(RecordSet[0]);

        }
        GC.Collect(); // AVOID
    }

TEST RESULT: CPU USAGE 12%

When you change to this:

        public void ClearFrame(ulong timeStamp)
    {
        if (RecordSet.Count <= 0) return;
        if (Limit == false)
        {
            var seconds = (timeStamp - RecordSet[0].TimeStamp)/1000;
            if (seconds <= _preFramesTime) return;
            Limit = true;
            do
            {
                RecordSet[0].Dispose(); //  Bitmap destroyed!
                RecordSet.Remove(RecordSet[0]);
            } while (((timeStamp - RecordSet[0].TimeStamp) / 1000) > _preFramesTime);
        }
        else
        {
            RecordSet[0].Dispose(); //  Bitmap destroyed!
            RecordSet.Remove(RecordSet[0]);

        }

By using sscanf we can convert string to float.

#include<stdio.h>    
#include<string.h>    

int main() 
{
    char str[100] ="4.0800" ;     
    const char s[2] = "-";   
    char *token;
    double x;
   /* get the first token */ 
   token = strtok(str, s);
   sscanf(token,"%f",&x);
    printf( " %f",x );

    return 0; 
}

Well, this question was asked years ago. I think technology has changed quite a bit and browser compatibility is much better. You could use vertical-align but I would consider that some what less scaleable and less reusable. I would recommend a flexbox approach.

Here is the same example the original poster used but with flexbox. It styles a single element. If a button size changes for whatever reason, it will continue to be vertically and horizontally centered.

.button {
    border: 1px solid #ccc;
    height: 40px;
    margin: 60px;
    padding: 4px;
    display: flex;
    justify-content: space-around;
    align-items: center;
}

In C++, a derived class object can be assigned to a base class object, but the other way is not possible.

class Base { int x, y; };

class Derived : public Base { int z, w; };

int main() 
{
    Derived d;
    Base b = d; // Object Slicing,  z and w of d are sliced off
}

Object slicing happens when a derived class object is assigned to a base class object, additional attributes of a derived class object are sliced off to form the base class object.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

My guess is that you don't really want to GROUP BY some_product.

The answer to: "Is there a way to GROUP BY a column alias such as some_product in this case, or do I need to put this in a subquery and group on that?" is: You can not GROUP BY a column alias.

The SELECT clause, where column aliases are assigned, is not processed until after the GROUP BY clause. An inline view or common table expression (CTE) could be used to make the results available for grouping.

Inline view:

select ...
from (select ... , CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END AS some_product
   from ...
   group by col1, col2 ... ) T
group by some_product ...

CTE:

with T as (select ... , CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END AS some_product
   from ...
   group by col1, col2 ... )
select ...
from T
group by some_product ... 

you can get all product information from following code

$product_id=6//Suppose
$_product=Mage::getModel('catalog/product')->load($product_id);


    $product_data["id"]=$_product->getId();
    $product_data["name"]=$_product->getName();
    $product_data["short_description"]=$_product->getShortDescription();
    $product_data["description"]=$_product->getDescription();
    $product_data["price"]=$_product->getPrice();
    $product_data["special price"]=$_product->getFinalPrice();
    $product_data["image"]=$_product->getThumbnailUrl();
    $product_data["model"]=$_product->getSku();
    $product_data["color"]=$_product->getAttributeText('color'); //get cusom attribute value


    $storeId = Mage::app()->getStore()->getId();
    $summaryData = Mage::getModel('review/review_summary')->setStoreId($storeId)  ->load($_product->getId());
    $product_data["rating"]=($summaryData['rating_summary']*5)/100;

    $product_data["shipping"]=Mage::getStoreConfig('carriers/flatrate/price');

    if($_product->isSalable() ==1)
        $product_data["in_stock"]=1;
    else
        $product_data["in_stock"]=0;


    echo "<pre>";
    print_r($product_data);
    //echo "</pre>";

I believe you need to .f file as a parameter, not as a command-single-string. same with the "--domain "+i, which i would split in two elements of the list. Assuming that:

• you have the path set for FORTRAN executable,
• the ~/ is indeed the correct way for the FORTRAN executable

I would change this line:

subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])

to

subprocess.Popen(["FORTRAN", "~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain", i])

If that doesn't work, you should do a os.path.exists() for the .f file, and check that you can launch the FORTRAN executable without any path, and set the path or system path variable accordingly

[EDIT 6-Mar-2017]

As the exception, detailed in the original post, is a python exception from subprocess; it is likely that the WinError 2 is because it cannot find FORTRAN

I highly suggest that you specify full path for your executable:

for i in input:
    exe = r'c:\somedir\fortrandir\fortran.exe'
    fortran_script = r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f'
    subprocess.Popen([exe, fortran_script, "--domain", i])

if you need to convert the forward-slashes to backward-slashes, as suggested in one of the comments, you can do this:

for i in input:
    exe = os.path.normcase(r'c:\somedir\fortrandir\fortran.exe')
    fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[EDIT 7-Mar-2017]

The following line is incorrect:

exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe'

I am not sure why you have ~/ as a prefix for every path, don't do that.

for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe'
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[2nd EDIT 7-Mar-2017]

I do not know this FORTRAN or ftn95.exe, does it need a shell to function properly?, in which case you need to launch as follows:

subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)

You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess command.

Original answer

Yes, this is possible:

List<BigDecimal> bdList = new ArrayList<>();
//populate list
BigDecimal result = bdList.stream()
        .reduce(BigDecimal.ZERO, BigDecimal::add);

What it does is:

1. Obtain a List<BigDecimal>.
2. Turn it into a Stream<BigDecimal>

3. Call the reduce method.

   3.1. We supply an identity value for addition, namely BigDecimal.ZERO.

   3.2. We specify the BinaryOperator<BigDecimal>, which adds two BigDecimal's, via a method reference BigDecimal::add.

Updated answer, after edit

I see that you have added new data, therefore the new answer will become:

List<Invoice> invoiceList = new ArrayList<>();
//populate
Function<Invoice, BigDecimal> totalMapper = invoice -> invoice.getUnit_price().multiply(invoice.getQuantity());
BigDecimal result = invoiceList.stream()
        .map(totalMapper)
        .reduce(BigDecimal.ZERO, BigDecimal::add);

It is mostly the same, except that I have added a totalMapper variable, that has a function from Invoice to BigDecimal and returns the total price of that invoice.

Then I obtain a Stream<Invoice>, map it to a Stream<BigDecimal> and then reduce it to a BigDecimal.

Now, from an OOP design point I would advice you to also actually use the total() method, which you have already defined, then it even becomes easier:

List<Invoice> invoiceList = new ArrayList<>();
//populate
BigDecimal result = invoiceList.stream()
        .map(Invoice::total)
        .reduce(BigDecimal.ZERO, BigDecimal::add);

Here we directly use the method reference in the map method.

We encountered similar errors in a testing environment on a virtual machine. If the machine name changes due to VM cloning from a template, you can get this error.

If the computer name changed from OLD to NEW.

A job uses this stored procedure:

msdb.dbo.sp_sqlagent_has_server_access @login_name = 'OLD\Administrator'

Which uses this one:

EXECUTE master.dbo.xp_logininfo 'OLD\Administrator'

Which gives this SQL error 15404

select text from sys.messages where message_id = 15404;
Could not obtain information about Windows NT group/user '%ls', error code %#lx.

Which I guess is correct, under the circumstances. We added a script to the VM cloning/deployment process that re-creates the SQL login.

The normally used load command will work if you specify the object_pairs_hook parameter:

import json
from  collections import OrderedDict
with open('foo.json', 'r') as fp:
    metrics_types = json.load(fp, object_pairs_hook=OrderedDict)

When it is on server side, use web services - maybe RESTful with JSON.

• create a web service (for example with Tomcat)
• call its URL from JavaScript (for example with JQuery or dojo)

When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.

Below is example from documentation. Look at methodReturningString.

Java code:

public class MethodInvocation extends Applet {
    public void noArgMethod() { ... }
    public void someMethod(String arg) { ... }
    public void someMethod(int arg) { ... }
    public int  methodReturningInt() { return 5; }
    public String methodReturningString() { return "Hello"; }
    public OtherClass methodReturningObject() { return new OtherClass(); }
}

public class OtherClass {
    public void anotherMethod();
}

Web page and JavaScript code:

<applet id="app"
        archive="examples.jar"
        code="MethodInvocation" ...>
</applet>
<script language="javascript">
    app.noArgMethod();
    app.someMethod("Hello");
    app.someMethod(5);
    var five = app.methodReturningInt();
    var hello = app.methodReturningString();
    app.methodReturningObject().anotherMethod();
</script>

IRIs do not replace URIs, because only URIs (effectively, ASCII) are permissible in some contexts -- including HTTP.

Instead, you specify an IRI and it gets transformed into a URI when going out on the wire.

There is a limit to the total size of all columns inlined into the index definition. That said though, I have never had to create index that wide. To me, the bigger advantage is the fact that you can cover more queries with one index that has included columns as they don't have to be defined in any particular order. Think about is as an index within the index. One example would be the StoreID (where StoreID is low selectivity meaning that each store is associated with a lot of customers) and then customer demographics data (LastName, FirstName, DOB): If you just inline those columns in this order (StoreID, LastName, FirstName, DOB), you can only efficiently search for customers for which you know StoreID and LastName.

On the other hand, defining the index on StoreID and including LastName, FirstName, DOB columns would let you in essence do two seeks- index predicate on StoreID and then seek predicate on any of the included columns. This would let you cover all possible search permutationsas as long as it starts with StoreID.

From the Developer Guide:

android:id="@+id/my_button"

The at-symbol (@) at the beginning of the string indicates that the XML parser should parse and expand the rest of the ID string and identify it as an ID resource. The plus-symbol (+) means that this is a new resource name that must be created and added to our resources (in the R.java file). There are a number of other ID resources that are offered by the Android framework. When referencing an Android resource ID, you do not need the plus-symbol, but must add the android package namespace, like so:

android:id="@android:id/empty"

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

This maybe too late but No one provided a clear explanation of how the algorithm works

The idea of Dijkstra is simple, let me show this with the following pseudocode.

Dijkstra partitions all nodes into two distinct sets. Unsettled and settled. Initially all nodes are in the unsettled set, e.g. they must be still evaluated.

At first only the source node is put in the set of settledNodes. A specific node will be moved to the settled set if the shortest path from the source to a particular node has been found.

The algorithm runs until the unsettledNodes set is empty. In each iteration it selects the node with the lowest distance to the source node out of the unsettledNodes set. E.g. It reads all edges which are outgoing from the source and evaluates each destination node from these edges which are not yet settled.

If the known distance from the source to this node can be reduced when the selected edge is used, the distance is updated and the node is added to the nodes which need evaluation.

Please note that Dijkstra also determines the pre-successor of each node on its way to the source. I left that out of the pseudo code to simplify it.

From the menu bar: Project -> Properties -> Java Compiler

Enable project specific settings (checked) Uncheck "use Compliance from execution environment '.... Select the desired "compiler compliance level"

That will allow you to compile "1.5" code using a "1.6" JDK.

If you want to acutally use a 1.5 JDK to produce "1.5" compliant code, then install a suitable 1.5 JDK and tell eclipse where it is installed via:

Window -> preferences -> Installed JREs

And then go back to your project

Project -> properties -> Java Build Path -> libraries

remove the 1.6 system libaries, and: add library... -> JRE System LIbrary -> Alternate JRE -> The JRE you want.

Verify that the correct JRE is on the project's build path, save everything, and enjoy!

Old question, new answer. With C++11 we have the fancy new for loop:

for (const auto &s : schemas)
   names.push_back(s.first);

where schemas is a std::map and names is an std::vector.

This populates the array (names) with keys from the map (schemas); change s.first to s.second to get an array of values.

you can use the following to find the posted data.

data = json.loads(request.raw_post_data)

SELECT array_to_string(array(SELECT a FROM b),', ');

Will do as well.

An SMS Push is a message to tell the terminal to initiate the session. This happens because you can't initiate an IP session simply because you don't know the IP Adress of the mobile terminal. Mostly used to send a few lines of data to end recipient, to the effect of sending information, or reminding of events.

WAP Push is an SMS within the header of which is included a link to a WAP address. On receiving a WAP Push, the compatible mobile handset automatically gives the user the option to access the WAP content on his handset. The WAP Push directs the end-user to a WAP address where content is stored ready for viewing or downloading onto the handset. This wap address may be a page or a WAP site.

The user may “take action” by using a developer-defined soft-key to immediately activate an application to accomplish a specific task, such as downloading a picture, making a purchase, or responding to a marketing offer.

After placing the above code in Program.cs, follow these steps:

1. Right click on the project

2. Select "Properties"

3. Set "Output Type" to "Windows Application"

4. Startup object : namepace.Program

From Bash manual:

${#parameter}

The length in characters of the expanded value of parameter is substituted. If parameter is ‘’ or ‘@’, the value substituted is the number of positional parameters. If parameter is an array name subscripted by ‘’ or ‘@’, the value substituted is the number of elements in the array. If parameter is an indexed array name subscripted by a negative number, that number is interpreted as relative to one greater than the maximum index of parameter, so negative indices count back from the end of the array, and an index of -1 references the last element.

Length of strings, arrays, and associative arrays

string="0123456789"                   # create a string of 10 characters
array=(0 1 2 3 4 5 6 7 8 9)           # create an indexed array of 10 elements
declare -A hash
hash=([one]=1 [two]=2 [three]=3)      # create an associative array of 3 elements
echo "string length is: ${#string}"   # length of string
echo "array length is: ${#array[@]}"  # length of array using @ as the index
echo "array length is: ${#array[*]}"  # length of array using * as the index
echo "hash length is: ${#hash[@]}"    # length of array using @ as the index
echo "hash length is: ${#hash[*]}"    # length of array using * as the index

output:

string length is: 10
array length is: 10
array length is: 10
hash length is: 3
hash length is: 3

Dealing with $@, the argument array:

set arg1 arg2 "arg 3"
args_copy=("$@")
echo "number of args is: $#"
echo "number of args is: ${#@}"
echo "args_copy length is: ${#args_copy[@]}"

output:

number of args is: 3
number of args is: 3
args_copy length is: 3

I know this thread is old now but I am answering it to keep things a bit updated.

With Angular 1.4 and above you can directly use limitTo filter which apart from accepting the limit parameter also accepts a begin parameter.

Usage: {{ limitTo_expression | limitTo : limit : begin}}

So now you may not need to use any third party library to achieve something like pagination. I have created a fiddle to illustrate the same.

I have a set of scripting functions that I use extensively on my Red Hat system. They use the system functions from /etc/init.d/functions to print green [ OK ] and red [FAILED] status indicators.

You can optionally set the $LOG_STEPS variable to a log file name if you want to log which commands fail.

Usage

step "Installing XFS filesystem tools:"
try rpm -i xfsprogs-*.rpm
next

step "Configuring udev:"
try cp *.rules /etc/udev/rules.d
try udevtrigger
next

step "Adding rc.postsysinit hook:"
try cp rc.postsysinit /etc/rc.d/
try ln -s rc.d/rc.postsysinit /etc/rc.postsysinit
try echo $'\nexec /etc/rc.postsysinit' >> /etc/rc.sysinit
next

Output

Installing XFS filesystem tools:        [  OK  ]
Configuring udev:                       [FAILED]
Adding rc.postsysinit hook:             [  OK  ]

Code

#!/bin/bash

. /etc/init.d/functions

# Use step(), try(), and next() to perform a series of commands and print
# [  OK  ] or [FAILED] at the end. The step as a whole fails if any individual
# command fails.
#
# Example:
#     step "Remounting / and /boot as read-write:"
#     try mount -o remount,rw /
#     try mount -o remount,rw /boot
#     next
step() {
    echo -n "$@"

    STEP_OK=0
    [[ -w /tmp ]] && echo $STEP_OK > /tmp/step.$$
}

try() {
    # Check for `-b' argument to run command in the background.
    local BG=

    [[ $1 == -b ]] && { BG=1; shift; }
    [[ $1 == -- ]] && {       shift; }

    # Run the command.
    if [[ -z $BG ]]; then
        "$@"
    else
        "$@" &
    fi

    # Check if command failed and update $STEP_OK if so.
    local EXIT_CODE=$?

    if [[ $EXIT_CODE -ne 0 ]]; then
        STEP_OK=$EXIT_CODE
        [[ -w /tmp ]] && echo $STEP_OK > /tmp/step.$$

        if [[ -n $LOG_STEPS ]]; then
            local FILE=$(readlink -m "${BASH_SOURCE[1]}")
            local LINE=${BASH_LINENO[0]}

            echo "$FILE: line $LINE: Command \`$*' failed with exit code $EXIT_CODE." >> "$LOG_STEPS"
        fi
    fi

    return $EXIT_CODE
}

next() {
    [[ -f /tmp/step.$$ ]] && { STEP_OK=$(< /tmp/step.$$); rm -f /tmp/step.$$; }
    [[ $STEP_OK -eq 0 ]]  && echo_success || echo_failure
    echo

    return $STEP_OK
}

Use print_r($votes); to inspect the array $votes, you will see that key 0 does not exist there. It will return NULL and throw that error.

you would need a parking lot, that holds a multi-dimensional array (specified in the constructor) of a type "space". The parking lot can keep track of how many spaces are taken via calls to functions that fill and empty spaces.Space can hold an enumerated type that tells what kind of space it is. Space also has a method taken(). for the valet parking, just find the first space thats open and put the car there. You will also need a Car object to put in the space, that holds whether it is a handicapped, compact, or regular vehicle.

class ParkingLot
{
    Space[][] spaces;

    ParkingLot(wide, long); // constructor

    FindOpenSpace(TypeOfCar); // find first open space where type matches
}

enum TypeOfSpace = {compact, handicapped, regular };
enum TypeOfCar = {compact, handicapped, regular };

class Space
{
    TypeOfSpace type;
    bool empty;
    // gets and sets here
    // make sure car type
}

class car
{
    TypeOfCar type;
}

here is Iframe in view:

<iframe class="img-responsive" id="ifmReport" width="1090" height="1200" >

    </iframe>

Load it in script:

 $('#ifmReport').attr('src', '/ReportViewer/ReportViewer.aspx');

Try cast result to numeric

CAST(sum(cast(datediff(second, IEC.CREATE_DATE, IEC.STATUS_DATE) as float) / 60)
    AS numeric(10,2)) TotalSentMinutes

Input

1
2
3

Output

1.00
2.00
3.00

If you don't have repeated values, you could use set difference.

x = set(range(10))
y = x - set([2, 3, 7])
# y = set([0, 1, 4, 5, 6, 8, 9])

and then convert back to list, if needed.

As others said, you simply put :not(.class). For CSS selectors, I recommend visiting this link, it's been very helpful throughout my journey: https://code.tutsplus.com/tutorials/the-30-css-selectors-you-must-memorize--net-16048

div:not(.success) {
  color: red;
}

The negation pseudo class is particularly helpful. Let's say I want to select all divs, except for the one which has an id of container. The snippet above will handle that task perfectly.

Or, if I wanted to select every single element (not advised) except for paragraph tags, we could do:

*:not(p) {
  color: green;
}

Customizing FROM address

MESSAGE="SOME MESSAGE"
SUBJECT="SOME SUBJECT"
TOADDR="[email protected]"
FROM="DONOTREPLY"

echo $MESSAGE | mail  -s "$SUBJECT" $TOADDR  -- -f $FROM

I had the same issue and as the above comments, thought there must be a native method in JavaScript. The thing is new Date(valueofdate) returns a Date object.

But, check in http://www.w3schools.com/js/js_date_formats.asp, the part that says leading zero. A date from a String, for example an echo from PHP, must be like:

$valueofdate = date('Y-n-j',strtotime('theStringFromQuery'));

This will pass a String, for example: '1999-3-3' and JavaScript will do the parsing to an object with right format with

$scope.valueofdate = new Date(valueofdate);

<input ui-date ui-date-format="mm/dd/yyyy" ng-model="valueofdate" />
<input type="date" ng-model="valueofdate" />

Link to PHP for date formats: http://www.w3schools.com/php/func_date_date_format.asp.

A backslash needs to be escaped with another backslash.

print('\\')

try this:

import time
import os

n = 0
for x in range(10): #enter your value here
    print(n)
    time.sleep(1) #to wait a second
    os.system('cls') #to clear previous number
                     #use ('clear') if you are using linux or mac!
    n = n + 1

My mistake was the I named the file packages.json instead of package.json

Most of information here are correct.
Here a compilation of them and my way of using them.

The idea is to stick to the recommended approach (build specific and no impact on other stored docker objects) and to try the more radical approach (not build specific and with impact on other stored docker objects) when it is not enough.

Recommended approach :

1) Force the execution of each step/instruction in the Dockerfile :

docker build --no-cache 

or with docker-compose build :

docker-compose build --no-cache

We could also combine that to the up sub-command that recreate all containers:

docker-compose build --no-cache &&
docker-compose up -d --force-recreate 

These way don't use cache but for the docker builder and the base image referenced with the FROM instruction.

2) Wipe the docker builder cache (if we use Buildkit we very probably need that) :

docker builder prune -af

3) If we don't want to use the cache of the parent images, we may try to delete them such as :

docker image rm -f fooParentImage

In most of cases, these 3 things are perfectly enough to allow a clean build of our image.
So we should try to stick to that.

More radical approach :

In corner cases where it seems that some objects in the docker cache are still used during the build and that looks repeatable, we should try to understand the cause to be able to wipe the missing part very specifically. If we really don't find a way to rebuild from scratch, there are other ways but it is important to remember that these generally delete much more than it is required. So we should use them with cautious overall when we are not in a local/dev environment.

1) Remove all images without at least one container associated to them :

docker image prune -a

2) Remove many more things :

docker system prune -a

That says :

WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all images without at least one container associated to them
  - all build cache

Using that super delete command may not be enough because it strongly depends on the state of containers (running or not). When that command is not enough, I try to think carefully which docker containers could cause side effects to our docker build and to allow these containers to be exited in order to allow them to be removed with the command.

A one liner shell script to remove a file if it already exist (based on Jindra Helcl's answer):

[ -f file ] && rm file

or with a variable:

#!/bin/bash

file="/path/to/file.ext"
[ -f $file ] && rm $file

Besides CMAKE_GENERATOR_PLATFORM variable, there is also the -A switch

cmake -G "Visual Studio 16 2019" -A Win32
cmake -G "Visual Studio 16 2019" -A x64

https://cmake.org/cmake/help/v3.16/generator/Visual%20Studio%2016%202019.html#platform-selection

  -A <platform-name>           = Specify platform name if supported by
                                 generator.

To use native-library (so files) You need to add some codes in the "build.gradle" file.

This code is for cleaing "armeabi" directory and copying 'so' files into "armeabi" while 'clean project'.

task copyJniLibs(type: Copy) {
    from 'libs/armeabi'
    into 'src/main/jniLibs/armeabi'
}
tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn(copyJniLibs)
}
clean.dependsOn 'cleanCopyJniLibs'

I've been referred from the below. https://gist.github.com/pocmo/6461138

Try this solution:

for m in ["a", "á", "à", "ã", "â"]:
    try:
        somelist.remove(m)
    except:
        pass

Just for your information. and and or operators are also using to return values. It is useful when you need to assign value to variable but you have some pre-requirements

operator or returns first not null value

#init values
a,b,c,d = (1,2,3,None)

print(d or a or b or c)
#output value of a - 1

print(b or a or c or d)
#output value of b - 2

Operator and returns last value in the sequence if any of the members don't have None value or if they have at least one None value we get None

print(a and d and b and c)
#output: None

print(a or b or c)
#output value of c - 3

Working gradle dependency

Try this:

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

First, see if you have splitunc() as an available function within os.path. The first item returned should be what you want... but I am on Linux and I do not have this function when I import os and try to use it.

Otherwise, one semi-ugly way that gets the job done is to use:

>>> pathname = "\\C:\\mystuff\\project\\file.py"
>>> pathname
'\\C:\\mystuff\\project\\file.py'
>>> print pathname
\C:\mystuff\project\file.py
>>> "\\".join(pathname.split('\\')[:-2])
'\\C:\\mystuff'
>>> "\\".join(pathname.split('\\')[:-1])
'\\C:\\mystuff\\project'

which shows retrieving the directory just above the file, and the directory just above that.

You can use the following CSS for your input field:

.center-block {
  display: block;
  margin-right: auto;
  margin-left: auto;
}

Then,update your input field as following:

<input class="center-block" type="button" value="Some Button">

Here's another variation that worked for me.

IF NOT EXISTS (SELECT 1
        FROM INFORMATION_SCHEMA.COLUMNS
        WHERE upper(TABLE_NAME) = 'TABLENAME'
        AND upper(COLUMN_NAME) = 'COLUMNNAME')
BEGIN
    ALTER TABLE [dbo].[Person] ADD Column
END
GO

EDIT: Note that INFORMATION_SCHEMA views may not always be updated, use SYS.COLUMNS instead:

IF NOT EXISTS (SELECT 1 FROM SYS.COLUMNS....
