Right. in database design, if a design isn't working, we turn it upside-down. I understand what you have been saying all along, and that is what you just repeated above. I am asking you to turn it upside down, and consider looking at it differently. Of course you don't have to; I just don't understand why you did not react to what I wrote. It's like you didn't even read it. Which is fine. I don't really care, honestly. Happy new year!
