Hi Jack,
I'm expecting less than 10 records in the resulting set.
The BlockUnit table contains 337,253 records; the InteractionParts table
contains 279,953 records.
It takes currently 8.3 seconds to execute the query as I have it.
Erh, this is embarassing but I'm going to need some help re-writing it with
EXISTS...
Thanks for the help so far,
You haven't said which parts of the query is slow.
Try:
Just the subselect query.
If that's slow, try just the first part of the union.
If that's not slow, try the second part.
At least you'll know where to concentrate.
