Select 2 columns in one and combine them

Question

Is it possible to select 2 columns in just one and combine them   Example    select something   somethingElse as onlyOneColumn from someTable

User · Answer

The   operator should do the trick just fine  Keep something in mind though  if one of the columns is null or does not have any value  it will give you a NULL result  Instead  combine   with the function COALESCE and you ll be set    Here is an example    SELECT COALESCE column1       COALESCE column2     FROM table1     For this example  if column1 is NULL  then the results of column2 will show up  instead of a simple NULL    Hope this helps

Yes   SELECT CONCAT field1  field2  AS WHOLENAME FROM TABLE WHERE       will result in data set like   WHOLENAME field1field2

if one of the column is number i have experienced the oracle will think     as sum operator instead concatenation    eg   select  id   name  as one from table 1   id is numeric     throws invalid number exception  in such case you can    operator which is concatenation   select  id    name  as one from table 1

Yes it s possible  as long as the datatypes are compatible  If they aren t  use a CONVERT   or CAST    SELECT firstname         lastname AS name FROM customers

select column1           column2 as whole name FROM tablename    Here    is the concat operator used for concatenating them to single column and      inside    used for space between two columns

User · Answer

Yes  you can combine columns easily enough such as concatenating character data   select col1   col 2 as bothcols from tbl       or adding  for example  numeric data   select col1   col2 as bothcols from tbl       In both those cases  you end up with a single column bothcols  which contains the combined data  You may have to coerce the data type if the columns are not compatible

Your syntax should work  maybe add a space between the colums like  SELECT something         somethingElse as onlyOneColumn FROM someTable

None of the other answers worked for me but this did   SELECT CONCAT Cust First       Cust Last  AS CustName FROM customer

User · Answer

Yes  just like you did   select something   somethingElse as onlyOneColumn from someTable   If you queried the database  you would have gotten the right answer    What happens is you ask for an expression  A very simple expression is just a column name  a more complicated expression can have formulas etc in it
