I fail to see what any of this has to do with sqlite. I thought this was a mailing list for sqlite? Seeing queries (no pun intended) on sql statements is very subjective, especially with the limited data provided by the original poster. Everyone will give helpful advice, but it won't stop there, and as soon as the original poster has another query (no pun intended) which would result in a schema change, this would have to be explained, etc.
A specific group on SQL is required. Just my thoughts...
