I know with oracle you can run a cost on a query (or queries), I was wondering if MySQL has the same. I'm wondering which is really faster, the 3 separate, or the single complex...

Xenon 10-02-2002 09:17 AM
the single complex should also be faster, because it takes the infos just once out of the db and the just uses if, sum and count functions.

the 3 seperate would take the infos three times...
