Mysql 下面提到的SQL查询给出错误

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;

增加一个；到内部查询更新的结尾

您需要在IF语句中终止内部查询

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;

                `oc_ms_product` AS mp ON ms.seller_id = mp.seller_id);
        END IF;
    END;

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语句更改分号形式的标准分隔符；另一个//。
