Both queries would be same if there are no indexes. If you have function based index then upper(sepr)='Y' would be fast. A simple index then sepr='Y' would be fast. Seema Singh <oracledbam_at_hotmail.com> wrote:Hi, I'm having one query which is more frequntly access by user.

select id, lname from godev.user where upper(sepr)='Y'

This tables have 711180 rows out of 27 rows are having sepr equal to 'Y'.

select id, lname from dev.user where sepr='Y' Which query would be fast if sepr didn't have any indexes?

thanks
