you can use  rpad  in your select query and specify the size      select rpad a   20    rpad b  20  from x     where first parameter is your column name and second parameter is the size which you want to pad with

It looks like you are executing the query in sqlplus   Sqlplus needs to ensure that there is enough room in the column spacing so the maximum string size can be displayed 255    Usually  the solution is to use the column formatting options Run prior to the query  column A format A20  to reduce the maximum string size  lines that exceed this length will be displayed over multiple lines

User · Answer

SQL Plus will format the columns to hold the maximum possible value  which in this case is 255 characters   To confirm that your output does not actually contain those extra spaces  try this   SELECT          TRIM A         AS COLUMN A          TRIM B         AS COLUMN B FROM   MY TABLE    If the     characters are separated from your output  then that indicates that it s not spaces  but some other whitespace character that got in there  tabs  for example    If that is the case  then it is probably an input validation issue somewhere in your application   However  the most likely scenario is that the     characters will in fact touch the rest of your strings  thus proving that the whitespace is actually trimmed   If you wish to output them together  then the answer given by Quassnoi should do it   If it is purely a display issue  then the answer given by Tony Andrews should work fine

Say  we have a column with values consisting of alphanumeric characters and underscore only  We need to trim this column off all spaces  tabs or whatever white characters  The below example will solve the problem  The trimmed one and the original one both are being displayed for comparison  select      REGEXP REPLACE my column    A-Z  0-9               my column      my column      from my table

This sounds like an output formatting issue   If using SQL Plus  use the COLUMN command like this  assuming you want a maximum display width of 20 chars for each    column a format a20 column b format a20 select a  b from mytable

User · Answer

If I understand correctly  this is what you want  select  trim a     trim b  as combinedStrings from yourTable
