Yes, it does.
No, I don't think it does, upon further consideration and testing... I thought it did b/c I read, and misinterpreted the UNION documentation....
In your original question, you'd indicated that you only
wanted zips where *both* criteria were met -- enough CIRGs and enough
CILTs. By using a UNION, you'll be getting zips where *either* is met.
This is right.
No. The key is that each independent query was returing the results he
wanted - so, the UNION statement will simple append these two results into
one long dataset - the WHERE clause, criteria, or even the number of records
is really not affected.
So is this. If I just needed to know that quota had been met for EITHER, then this would work perfectly for me.
The key for my situation is that I need ONLY the records that exist in BOTH.
Any other thoughts for this, or am I bumping up against the limits of SQL in general?
Thanks again! -Cameron Wilhelm
