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.

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
