Tom, Back in the 7.0 days,
WHERE EXISTS (SELECT * FROM a WHERE condition) was significantly slower on broad tables than WHERE EXISTS (SELECT small_col FROM a WHERE condition) Is this still true, or something that's been fixed in the last 3 versions? Joe Celko is making fun of me because Oracle doesn't have this performance issue. -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
