Sigh. I assume, in your particular case then, you mean 'has no composite data types' when you use the nonsense-term flat?

I have no idea why you have choose define a relation again, and I'm going to try and ignore the word 'instance' in there. (I can only hope you are not relating a tuple to an object). Received on Wed Feb 22 2006 - 03:31:00 CET
