Subj:   Re: Nulls in a composite Primary Key deployed as a Primary Index
From:   Neil Raden

I think it's a horrible idea. I just don't see where null and key belong in the same sentence. Why not use a special value, like 9999, to designate the null condition(s) such as not known, incomplete. Besides, how can you have RI with a null key?
