The answer is
spool D:\test.txt
select * from emp
spool off
It's crude, but:
set pagesize 0 linesize 500 trimspool on feedback off echo off
select '"' || empno || '","' || ename || '","' || deptno || '"' as text
from emp
spool emp.csv
/
spool off
You could also use the following, although it does introduce spaces between fields.
set colsep , -- separate columns with a comma
set pagesize 0 -- No header rows
set trimspool on -- remove trailing blanks
set headsep off -- this may or may not be useful...depends on your headings.
set linesize X -- X should be the sum of the column widths
set numw X -- X should be the length you want for numbers (avoid scientific notation on IDs)
spool myfile.csv
select table_name, tablespace_name
from all_tables
where owner = 'SYS'
and tablespace_name is not null;
Output will be like:
TABLE_PRIVILEGE_MAP ,SYSTEM
SYSTEM_PRIVILEGE_MAP ,SYSTEM
STMT_AUDIT_OPTION_MAP ,SYSTEM
DUAL ,SYSTEM
...
This would be a lot less tedious than typing out all of the fields and concatenating them with the commas. You could follow up with a simple sed script to remove whitespace that appears before a comma, if you wanted.
Something like this might work...(my sed skills are very rusty, so this will likely need work)
sed 's/\s+,/,/' myfile.csv
There is a problem using sqlplus to create csv files. If you want the column headers only once in the output and there are thousands or millions of rows, you cannot set pagesize large enough not to get a repeat. The solution is to start with pagesize = 50 and parse out the headers, then issue the select again with pagesize = 0 to get the data. See bash script below:
#!/bin/bash
FOLDER="csvdata_mydb"
CONN="192.168.100.11:1521/mydb0023.world"
CNT=0376
ORD="0376"
TABLE="MY_ATTACHMENTS"
sqlplus -L logn/pswd@//${CONN}<<EOF >/dev/null
set pagesize 50;
set verify off;
set feedback off;
set long 99999;
set linesize 32767;
set trimspool on;
col object_ddl format A32000;
set colsep ,;
set underline off;
set headsep off;
spool ${ORD}${TABLE}.tmp;
select * from tblspc.${TABLE} where rownum < 2;
EOF
LINES=`wc -l ${ORD}${TABLE}.tmp | cut -f1 -d" "`
[ ${LINES} -le 3 ] && {
echo "No Data Found in ${TABLE}."
}
[ ${LINES} -gt 3 ] && {
cat ${ORD}${TABLE}.tmp | sed -e 's/ * / /g' -e 's/^ //' -e 's/ ,/,/g' -e 's/, /,/g' | tail -n +3 | head -n 1 > ./${ORD}${TABLE}.headers
}
sqlplus -L logn/pswd@//${CONN}<<EOF >/dev/null
set pagesize 0;
set verify off;
set feedback off;
set long 99999;
set linesize 32767;
set trimspool on;
col object_ddl format A32000;
set colsep ,;
set underline off;
set headsep off;
spool ${ORD}${TABLE}.tmp;
select * from tblspc.${TABLE};
EOF
LINES=`wc -l ${ORD}${TABLE}.tmp | cut -f1 -d" "`
[ ${LINES} -le 3 ] && {
echo "No Data Found in ${TABLE}."
}
[ ${LINES} -gt 3 ] && {
cat ${ORD}${TABLE}.headers > ${FOLDER}/${ORD}${TABLE}.csv
cat ${ORD}${TABLE}.tmp | sed -e 's/ * / /g' -e 's/^ //' -e 's/ ,/,/g' -e 's/, /,/g' | tail -n +2 | head -n -1 >> ${FOLDER}/${ORD}${TABLE}.csv
}
You should be aware that values of fields could contain commas and quotation characters, so some of the suggested answers would not work, as the CSV output file would not be correct. To replace quotation characters in a field, and replace it with the double quotation character, you can use the REPLACE function that oracle provides, to change a single quote to double quote.
set echo off
set heading off
set feedback off
set linesize 1024 -- or some other value, big enough
set pagesize 50000
set verify off
set trimspool on
spool output.csv
select trim(
'"' || replace(col1, '"', '""') ||
'","' || replace(col2, '"', '""') ||
'","' || replace(coln, '"', '""') || '"' ) -- etc. for all the columns
from yourtable
/
spool off
Or, if you want the single quote character for the fields:
set echo off
set heading off
set feedback off
set linesize 1024 -- or some other value, big enough
set pagesize 50000
set verify off
set trimspool on
spool output.csv
select trim(
'"' || replace(col1, '''', '''''') ||
'","' || replace(col2, '''', '''''') ||
'","' || replace(coln, '''', '''''') || '"' ) -- etc. for all the columns
from yourtable
/
spool off
I wrote this purely SQLPlus script to dump tables to CSV in 1994.
As noted in the script comments, someone at Oracle put my script in an Oracle Support note, but without attribution.
https://github.com/jkstill/oracle-script-lib/blob/master/sql/dump.sql
The script also also builds a control file and a parameter file for SQL*LOADER
prefer to use "set colsep" in sqlplus prompt instead of editing col name one by one. Use sed to edit the output file.
set colsep '","' -- separate columns with a comma
sed 's/^/"/;s/$/"/;s/\s *"/"/g;s/"\s */"/g' $outfile > $outfile.csv
I use this command for scripts which extracts data for dimensional tables (DW). So, I use the following syntax:
set colsep '|'
set echo off
set feedback off
set linesize 1000
set pagesize 0
set sqlprompt ''
set trimspool on
set headsep off
spool output.dat
select '|', <table>.*, '|'
from <table>
where <conditions>
spool off
And works. I don't use sed for format the output file.
I see a similar problem...
I need to spool CSV file from SQLPLUS, but the output has 250 columns.
What I did to avoid annoying SQLPLUS output formatting:
set linesize 9999
set pagesize 50000
spool myfile.csv
select x
from
(
select col1||';'||col2||';'||col3||';'||col4||';'||col5||';'||col6||';'||col7||';'||col8||';'||col9||';'||col10||';'||col11||';'||col12||';'||col13||';'||col14||';'||col15||';'||col16||';'||col17||';'||col18||';'||col19||';'||col20||';'||col21||';'||col22||';'||col23||';'||col24||';'||col25||';'||col26||';'||col27||';'||col28||';'||col29||';'||col30 as x
from (
... here is the "core" select
)
);
spool off
the problem is you will lose column header names...
you can add this:
set heading off
spool myfile.csv
select col1_name||';'||col2_name||';'||col3_name||';'||col4_name||';'||col5_name||';'||col6_name||';'||col7_name||';'||col8_name||';'||col9_name||';'||col10_name||';'||col11_name||';'||col12_name||';'||col13_name||';'||col14_name||';'||col15_name||';'||col16_name||';'||col17_name||';'||col18_name||';'||col19_name||';'||col20_name||';'||col21_name||';'||col22_name||';'||col23_name||';'||col24_name||';'||col25_name||';'||col26_name||';'||col27_name||';'||col28_name||';'||col29_name||';'||col30_name from dual;
select x
from
(
select col1||';'||col2||';'||col3||';'||col4||';'||col5||';'||col6||';'||col7||';'||col8||';'||col9||';'||col10||';'||col11||';'||col12||';'||col13||';'||col14||';'||col15||';'||col16||';'||col17||';'||col18||';'||col19||';'||col20||';'||col21||';'||col22||';'||col23||';'||col24||';'||col25||';'||col26||';'||col27||';'||col28||';'||col29||';'||col30 as x
from (
... here is the "core" select
)
);
spool off
I know it`s kinda hardcore, but it works for me...
I have once written a little SQL*Plus script that uses dbms_sql and dbms_output to create a csv (actually an ssv). You can find it on my githup repository.
I know this is an old thread, however I noticed that no one mentioned the underline option, which can remove the underlines under the column headings.
set pagesize 50000--50k is the max as of 12c
set linesize 10000
set trimspool on --remove trailing blankspaces
set underline off --remove the dashes/underlines under the col headers
set colsep ~
select * from DW_TMC_PROJECT_VW;
Use vi or vim to write the sql, use colsep with a control-A (in vi and vim precede the ctrl-A with a ctrl-v). Be sure to set the linesize and pagesize to something rational and turn on trimspool and trimout.
spool it off to a file. Then...
sed -e 's/,/;/g' -e 's/ *{ctrl-a} */,/g' {spooled file} > output.csv
That sed thing can be turned into a script. The " *" before and after the ctrl-A squeezes out all the useless spaces. Isn't it great that they bothered to enable html output from sqlplus but NOT native csv?????
I do it this way because it handles commas in the data. I turns them to semi-colons.
You could use csv hint. See the following example:
select /*csv*/ table_name, tablespace_name
from all_tables
where owner = 'SYS'
and tablespace_name is not null;
With newer versions of client tools, there are multiple options to format the query output. The rest is to spool it to a file or save the output as a file depending on the client tool. Here are few of the ways:
- SQL*Plus
Using the SQL*Plus commands you could format to get your desired output. Use SPOOL to spool the output to a file.
For example,
SQL> SET colsep ,
SQL> SET pagesize 20
SQL> SET trimspool ON
SQL> SET linesize 200
SQL> SELECT * FROM scott.emp;

SQL>
- SQL Developer Version pre 4.1
Alternatively, you could use the new /*csv*/ hint in SQL Developer.
/*csv*/
For example, in my SQL Developer Version 3.2.20.10:
Now you could save the output into a file.
- SQL Developer Version 4.1
New in SQL Developer version 4.1, use the following just like sqlplus command and run as script. No need of the hint in the query.
SET SQLFORMAT csv
Now you could save the output into a file.
You can explicitly format the query to produce a delimited string with something along the lines of:
select '"'||foo||'","'||bar||'"'
from tab
And set up the output options as appropriate. As an option, the COLSEP variable on SQLPlus will let you produce delimited files without having to explicitly generate a string with the fields concatenated together. However, you will have to put quotes around strings on any columns that might contain embedded comma characters.
