Re: User define functions (queries) in SELECT statements

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.

What do the before (V7) and after (V8) explain plans look like? Have you (re)analyzed all tables & indexes used by the query?

The future is here. It is just not evenly distributed.
