You probably need to rethink your hierarchy.  If you want to persist
with inheritance, you could define another table, student_employee,
which multiply-inherits student and employee.

Incidentally, `user' is a reserved word; you will have to change the
table name for 7.0.3, or else double-quote it every time you use it.
