Hello
I changed implementation of SQLSTATE from block scope variables on
function scope variables. I am not sure if it's moust elegant solution,
but is very similar Oracle behavior (there is session scope variable)
CREATE OR REPLACE FUNCTION ff() RETURNS void AS $$
BEGIN
RAISE NOTICE 'No exception: % %', SQLSTATE, SQLERRM;
DECLARE x integer;
BEGIN
x := 10/0;
EXCEPTION WHEN OTHERS THEN
BEGIN
RAISE NOTICE 'Div: % %', SQLSTATE, SQLERRM;
BEGIN
RAISE NOTICE 'Div2: % %', SQLSTATE, SQLERRM;
RAISE EXCEPTION 'My user exception';
EXCEPTION WHEN OTHERS THEN
RAISE NOTICE 'User: % %', SQLSTATE, SQLERRM;
END;
RAISE NOTICE '1: % %', SQLSTATE, SQLERRM;
END;
RAISE NOTICE '2: % %', SQLSTATE, SQLERRM;
END;
RAISE NOTICE '3: % %', SQLSTATE, SQLERRM;
END;
$$ LANGUAGE plpgsql;
select ff();
NOTICE: No exception: 00000 Successful completion
NOTICE: Div: 22012 division by zero
NOTICE: Div2: 22012 division by zero
NOTICE: User: P0001 My user exception
NOTICE: 1: 00000 Successful completion
NOTICE: 2: 00000 Successful completion
NOTICE: 3: 00000 Successful completion
Any comments?
Regards
