嗨，我是新來mysql.here我寫了錯誤發生的過程：

DELIMITER $$ 

USE `flower2`$$ 

DROP PROCEDURE IF EXISTS `test`$$ 

CREATE PROCEDURE `test`() 

BEGIN 

DECLARE soldcount INT; 

DECLARE goodsid INT; 

DECLARE not_found INT; 

DECLARE curGoodsId CURSOR FOR SELECT goods_id FROM ecs_order_goods; 

DECLARE curSoldCount CURSOR FOR SELECT sold_count FROM ecs_goods; 

DECLARE CONTINUE HANDLER FOR NOT FOUND SET not_found = 1; 

DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK; 

START TRANSACTION; 

OPEN curGoodsId; 

OPEN OPEN curSoldCount; 

WHILE not_found = 0 DO 

FETCH curSoldCount INTO soldcount; 

FETCH curGoodsId INTO goodsid; 

    SELECT COUNT(goods_id) FROM ecs_order_goods INTO soldcount; 

    UPDATE ecs_goods SET sold_count=soldcount WHERE goods_id=goodsid; 

IF NOT not_found THEN 

    SET not_found = 0 ; 

END IF; 

END WHILE; 

CLOSE curGoodsId; 

CLOSE curSoldCount; 

COMMIT;

Answer 1

你寫

OPEN OPEN curSoldCount; 

嘗試

OPEN curSoldCount; 

OMG！
