I am thinking, so I propose a enough solution for you - when you use CTE for execution of VOID function, then result vill be VOID set, what we can accept as undefined result, and in this case a PERFORM should not be required. If CTE will return some result, then PERFORM should be required and PERFORM must to support CTE in all possible modes - updateable or not updateable queries. Regards Pavel > > Best, > > David > >
