It's obvious that you haven't given us anything remotely like full
information here.  AFAICT the "tables" in your view are actually
other views, plus it looks like your call to the view is a query
that adds some other conditions you didn't mention.  (Or are those
conditions coming from the sub-views?  Hard to tell.)  If you want
useful help you need to be more complete.
