Reality is that the "Key" is a combination of 3 or 4 fields. I suppose I can concatenate the fields, but that seems overly ugly. And the select and existing part of the where clause are complicated, so if I can avoid repeating all of that, I'd rather avoid doing it as a union query. But if needs must, I will go with this idea.
