problema assertion

Posted by stell4r on 10-10-2008 15:43

stavo leggendo su http://www.postgresql.org/files/doc...ql/node221.html come implementare le asserzioni quando leggo questa frase.

CONSTRAINT clause

SQL92 specifies some additional capabilities for constraints, and also defines assertions and domain constraints. Note: Postgres does not yet support either domains or assertions.

Ho provato a creare un assertion in postgre ed il risultato è:

ERROR: CREATE ASSERTION is not yet implemented

********** Errore **********

ERROR: CREATE ASSERTION is not yet implemented
Stato SQL: 0A000

possibile che postgre non supporti gli assertion?voi siete riusciti a crearli?
