    According to the MySQL documentation:

    There can be only one AUTO_INCREMENT column per table, it must be indexed, and it cannot have a DEFAULT value.

    So as long as you satisfy those conditions, there’s no mention that it has to also be the primary key. So you should be able to have the primary key and a separate AUTO_INCREMENT column (though I’m not sure why you’d want to).
