Sure there is! There are queries that benefit from having a temporary table created for a subquery and the temporary tableindexed before the join. Since we can't easily return result sets from functions yet, it's not probably used that much,but from within a function, I can see why you might want to do this from time to time. Ian A.

I'm kind of surprised that it's possible to index a temporary table.There's not much point in doing so. Yes, the indexes would be dropped as well. -Josh Berkus ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
