I'm really beginning to wonder if we need to write special SQL
based on the database we're using in order to tune the performance
because of issues like this?  Yes, I know that that sort of defeats
the purpose of using a library like GDA, but if GDA can't form
an optimal query then it might behoove us to do the right thing
rather than hope they do.
