I tried to use the following code to retrieve the content of table1 4
times (in my application, the total number of refcursors that will be
returned is determined by the data in the database). I am getting the
error message says "ERROR: cursor "<unnamed portal 2>" already in
use".
Thank you in advance!
dl
--Start of the code
--DROP FUNCTION myfunc(int);
CREATE FUNCTION myfunc(int) RETURNS SETOF refcursor AS $$
DECLARE i int;
r refcursor;
BEGIN
i := $1;
WHILE i>0 LOOP
RAISE NOTICE 'loop count %;', i;
i := i-1;
OPEN r FOR SELECT * FROM table1;
RETURN NEXT r;
END LOOP;
RETURN;
END;
$$ LANGUAGE plpgsql;
BEGIN;
SELECT * FROM myfunc(4);
COMMIT;
