mysql - 错误代码: 1324 Undefined CURSOR: OPEN

Question

嘿伙计们，我是mysql新手。这里我写了一个发生错误的程序:

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;

END$$

DELIMITER ;

Answer 1

你写的

OPEN OPEN curSoldCount;

尝试

OPEN curSoldCount;
