Re: PERFORM statement inside procedure

Actually my problem is PERFORM is not updating the FOUND variable to false
even when my query return no rows. Can you please tell me the better way to
use PERFORM so that by running my select query I just come to know whether
it returns 0 rows or not.

Regards,
Rajat.
