BradD Posted June 30, 2010 Share Posted June 30, 2010 If I have 16 entries in my table and have( id PRIMARY AI ), (username UNIQUE), (email UNIQUE) SHOULD username hold the same Cardinal Value as id and email which are 16? It's just that the Cardinal value of username is 0 and I'm pretty sure it should also be 16 along with id and email.
