Hm. My knowledge of SQL is not very good, so I do not dare to say yes or no. I would rather try to give an example. Using OWL in Turtle syntax:

:Book owl:hasKey ( :edition :binding ) .

:b1 a :Book.
:b2 a :Book.
:b3 a :Book.

:b1 :edition 1.0.
:b2 :edition 1.0.
:b3 :edition 1.0.

:b1 :binding "hb".
:b2 :binding "hb".
:b3 :binding "pb".

an OWL reasoner may deduce that

:b1 owl:sameAs :b2.

but it does _not_ allow it to deduce that

:b1 owl:sameAs :b3.

Actually, if I stated, additionally, that

:b1 owl:sameAs :b3.

then an OWL reasoner is allowed to shoot me down.

It is not exactly the same, of course, because I am not sure the identity of the instances and the identity of ISBN-s is, hm, identical:-), but the melody is similar.
