If you want comma separated fields, then set the column separator from '|' to \,' like this
SET COLSEP ',' now a select * from tableX; will have commas between each column.

[Quoted] Why do you think you need to TRIM the data? If you are producing a CSV file, who cares about trailing whitespace? That's an issue for the loader to deal with.

[Quoted] [Quoted] If you know the max length of your output DATA , then you can use the TRUNCATE option on the COLUMN command to minimize the trailing spaces.

[Quoted] [Quoted] Or use the combination of COLSEP and TRIM()

SET COLSET ','
SELECT RTRIM(cola) columnone, RTRIM(colb) columntwo FROM yourtable ;

should do as you need.
