Обсуждение: Return cursor

Hi!

I need to return a cursor from a function/procedure?
How can I do it?

Thanks,

CGS

CREATE FUNCTION reffunc2() RETURNS refcursor AS '
 DECLARE
         ref refcursor;
 BEGIN
         OPEN ref FOR SELECT col FROM test;
         RETURN ref;
 END;
 ' LANGUAGE 'plpgsql';
