过程不返回或修改任何行

Question

以下是我没有修改任何记录的程序。当我在peices中运行时，一切正常。我假设我没有正确使用我的变量。谁能确认一下？谢谢。

BEGIN
DECLARE a, b, c, d, e INT;
DECLARE cur1 CURSOR FOR SELECT a.team_id, a.league_id, a.bid, f.roster_id, f.winning_team_id FROM kl_faa f, kl_faa_audit a, faa_times t WHERE t.id = f.faa_times_id AND f.id = a.faa_id AND f.auction_end_date IS NULL AND (DATE_ADD(f.last_bid_date, INTERVAL t.hours HOUR)) <= NOW() AND a.faa_id != (SELECT MAX(ref_id) FROM kl_faa_audit WHERE faa_id = a.faa_id);
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
OPEN cur1;

read_loop: LOOP
FETCH cur1 INTO a, b, c, d, e;
UPDATE kl_user_league SET cash_balance = cash_balance + @c    WHERE league_id = @b and team_id = @a;
END LOOP;

CLOSE cur1;

UPDATE kl_team_roster SET team_id = @e, status = 0 WHERE roster_id = @d;

UPDATE kl_faa f LEFT JOIN faa_times t ON t.id = f.faa_times_id
SET f.auction_end_date = NOW()
WHERE t.id = f.faa_times_id AND f.auction_end_date IS NULL AND (DATE_ADD(f.last_bid_date, INTERVAL t.hours HOUR)) <= NOW();
END;
END
