php - mysql 触发器中遇到错误

Question

我正在 mysql 中创建触发器，但遇到错误。

我想做的是，当状态更新并设置为 1 时，我必须检查买家是否也处于事件状态，然后我必须更新状态。

        DELIMITER //
        CREATE TRIGGER `after_vendor_update` AFTER DELETE ON `data_vendor`
        FOR EACH ROW BEGIN
        IF(NEW.vendor_status = 1)
            UPDATE vendor_setting SET  `buyer_setting_status` = NEW.vendor_status WHERE buyerid IN (SELECT bid FROM data_buyer WHERE buyer_status='1');
        ELSE
            UPDATE vendor_setting SET  `buyer_setting_status` = NEW.vendor_status;
        END IF;
        END
        //
