IF(EXTRACT(DAY,[SQL1].[PROCESS_DATE]) BETWEEN 1 AND 15) THEN
(CAST(EXTRACT(YEAR,[SQL1].[PROCESS_DATE]),VARCHAR(10))+15) ELSE
([SQL1].[PROCESS_DATE])

      An error occurred while performing operation 'sqlScrollBulkFetch' status='-232'.

Database is DB2

I do not think that is possible to add 15 (number) to a varchar.

What r you trying to achieve?
For example if you have a date 13/10/2012 you want to get 2027 or 13/10/2027?

Furhtermore I am not a db2 expert but in my expirience so far from an if statement you should get same data types in if and else statement. In your situation in if you will get a varchar and in else a date.
