Re: Optimizer - subqueries

Thanks Felix, I'll give this a try.....

I've actually been forced to "create" a permanent table now to reflect the "subquery". (which takes around 5 seconds to populate)

If its permanent, then it doesn't have to do the subquery first, so the query runs in around 10 seconds.....

this is slightly better than the optimizer deciding that the outer part should be run first and me cancelling it after 30 minutes!!!

cheers though for your help.

Jake
