Thanks for replying. I need to start this by correcting the subject line I put on this originally. I am talking about user-defined FUNCTIONS within a SELECT. Sorry. The explain plans look exactly the same. Strangely enough, the small tables that are read in the user-defined functions do NOT appear in the explain plan (!?!?!?!?!!?). Yes.....we did re-analyze after the software upgrade. Thanks again.

Have you (re)analyzed all tables & indexes used by the query?
