Forgive me if this sounds rude because I'm not meaning it as such, but
this suggestion sounds like a MySQL-ish hack.  No doubt it would work,
but should an application-writer have to incur the cost of writing
something different because the database can't handle it?  I remember
having to write subselect code in PHP because MySQL couldn't do it...
not what I would call a *solution* by any mean.
