PK can not be NULLable :-)
What you mean with
default PK value?
For me PK must always have value and it must be not null.
Zero is meaning digit, but you can't have more than one record with zero in it.
BTW PK's often didn't carry any meaning information in them. I use Identity fields, other prefer uniquidentifiers.
So the whole debate is useless :-)) (at least for me).
