In that pretty much all commercial implementations of SQL have 
iteration, I believe (am not 100% -- Enrico?) that they are 
computationally complete.  That said, that makes them more expressive 
than any flavor of OWL.

Now, why anyone would want to use SQL DML to express constraints I 
don't know.  Jim is right if he's trying to make the point that OWL is 
declarative and declarative is the way to go.
