OPEN unbound_cursor [ [ NO ] SCROLL ] FOR EXECUTE query_string;

Hi Pavel,
thanks a lot. It works for me like this:
CREATE OR REPLACE FUNCTION user_cursor_test(refcursor,text) RETURNS refcursor
AS $$
BEGIN
OPEN $1 FOR EXECUTE 'SELECT name FROM ' || $2;
RETURN $1;
END; $$ LANGUAGE plpgsql;
Cheers

Hi,
short question. Why is this not possible:
CREATE OR REPLACE FUNCTION user_cursor_open(text) RETURNS refcursor AS $$
DECLARE
curs1 CURSOR FOR SELECT * FROM $1;
BEGIN
OPEN curs1;
RETURN curs1;
END; $$ LANGUAGE plpgsql;
Or, how do I set a parameter when using cursor?
Thanks in advance
