SQL, as a set-oriented language, composes just fine. • views • CTEs • temporary tables • set-returning functions It will not compose like an OO language or like a functional language because it isn't one of those. It's set-oriented. This is the biggest hangup I've seen from folk who hate SQL: mistaking it for something it isn't, never was, and was never intended to be given its problem domain.
