Utility of GRANT EXECUTE

["Paul Mackay" <mackaypaul@xxxxxxxxx>]

It seems that any user has the right to execute a function, whether or not it has been granted the EXECUTE privilege on it. Even a REVOKE EXECUTE has no impact. A privilige error will be raised only if the function tries to access an object (ex.: a table) for witch the user doesn't have the appropriate privilege(s).

Is there any utility to the GRANT EXECUTE then ? 


Thanks,
Paul
