Autonumber fields make excellent Primary Keys.


You've misunderstood what PRIMARY KEY means. An unique integer which
has no meaning in respect fo the entities being modelled makes a lousy
PRIMARY KEY. Google for "clustered index" in the Access groups.

An autonumber is a convenient uniqueifier but unquieness for its own
sake make not be such a good thing.
