Well I don't know if we understand each other. If I have a ForeignKey defined with ondelete='RESTRICT', and I delete the parent, no errors are thrown. This only becomes apperent when you have a foreign key that is NOT defined as non-nullable. Even if you define it to be non-nullable, the error thrown when you try to delete the parent is not "update or delete on table <parent_table> violates foreign key constraint", but "null value in column <child_column> violates not-null constraint". I've created a ticket (http://www.sqlalchemy.org/trac/ticket/1594) with more details and a test case to make it clearer. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
