In general, you would restrict the result based on the credentials given to the dbms. If those are application credentials, then the application can see what it is supposed to see. If those are user credentials, then the user can see what he or she is supposed to see.

The system catalog will reflect the credentials given (usually.) Received on Thu May 28 2009 - 23:10:14 CEST
