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. -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver PGP: 1024R/32B8FAA1: 97 EA 1D 47 72 3F 28 47 6B 7E 39 CC 56 E4 C1 47 GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "Wash me thoroughly from mine iniquity, and cleanse me from my sin.
