mysql - SQL查询给出下面提到的错误

Question

我有一个sql查询

CREATE DEFINER=`root`@`localhost` TRIGGER `trigger_vacation_mode` AFTER UPDATE ON `oc_ms_seller`
FOR EACH ROW
BEGIN
 if NEW.vacation_mode <> OLD.vacation_mode THEN

    UPDATE `oc_product` AS p
    SET p.date_modified = NOW()
    WHERE p.product_id IN (SELECT DISTINCT product_id FROM `oc_ms_seller` AS ms join
    `oc_ms_product` AS mp ON ms.seller_id = mp.seller_id)

 END IF;
END;

执行的时候报错

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'END IF
END' at line 11

Answer 1

您需要覆盖默认分隔符 (;)

DELIMITER //

CREATE DEFINER=`root`@`localhost` TRIGGER `trigger_vacation_mode` AFTER UPDATE ON `oc_ms_seller`
FOR EACH ROW
BEGIN
 if NEW.vacation_mode <> OLD.vacation_mode THEN

    UPDATE `oc_product` AS p
    SET p.date_modified = NOW()
    WHERE p.product_id IN (SELECT DISTINCT product_id FROM `oc_ms_seller` AS ms join
    `oc_ms_product` AS mp ON ms.seller_id = mp.seller_id);

 END IF;
END//

DELIMITER ;

DELIMITER 语句将标准分隔符从分号 (;) 更改为另一个(此处为 //)。
