Hi > This restriction is specified in the SQL standard. Thanks! This is the kind of thing one CAN sell to customers :) "Your thing is out of standards, Sir" sounds much better than "But I really hate that, Sir". Which has, however, a terrible impact on the ORM that use circular FKs. Will have to think this over very well.
