Hello
Statement CONTINUE isn't in PL/SQL too, I know it, but Oracle PL/SQL
has statement GOTO. I don't need GOTO statement, but 'continue' can be
very usefull for me. I have to do some ugly trick now. With little change,
we can enhance stmt EXIT for behavior continue.
After some work I can
CREATE OR REPLACE FUNCTION lll() RETURNS void AS $$
DECLARE i integer = 0;
BEGIN
LOOP
i = i + 1;
CONTINUE WHEN i < 10;
RAISE NOTICE '%', i;
EXIT;
END LOOP;
BEGIN
CONTINUE WHEN i = 10;
RAISE NOTICE '---1---';
END;
RAISE NOTICE '---2---';
FOR _i IN 1 .. 10 LOOP
CONTINUE WHEN _i < 5;
RAISE NOTICE '%', _i;
END LOOP;
END; $$ LANGUAGE plpgsql;
select lll();
pokus=# NOTICE: 10
NOTICE: ---2---
NOTICE: 5
NOTICE: 6
NOTICE: 7
NOTICE: 8
NOTICE: 9
NOTICE: 10
lll
-----
(1 row)
What do you think about it? It's broke PL/SQL compatibility, I know, but
via last discussion I have opinion so Oracle compatibility isn't main
objective PL/pgSQL. There is some less/bigger diferencess: SQLSTATE,
EXCEPTION from my last proposal, atd.
What do you think about it?
