Question

我有以下存储过程

DELIMITER //
CREATE TRIGGER OrderDetail_AFTER_INSERT AFTER INSERT ON OrderDetail
FOR EACH ROW
BEGIN
  UPDATE Order SET total = total + NEW.subtotal WHERE id = NEW.orderid;
END;
//
DELIMITER ;

我得到的错误是

ERROR 1064 <4200>: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version fir the right syntax to use ner 'Order SET total = total + NEW.subtotal WHERE id = NEW.orderid; END' at line 5

任何想法？请帮忙

Answer 1

订单是保留字。请把它放在它周围

DELIMITER //
CREATE TRIGGER OrderDetail_AFTER_INSERT AFTER INSERT ON OrderDetail
FOR EACH ROW
BEGIN
  UPDATE `Order` SET total = total + NEW.subtotal WHERE id = NEW.orderid;
END;
//
DELIMITER ;

试一试!!!

Answer 2

您似乎正在使用＆＃39;订购＆＃39;作为表名。在MySql中，＆＃39; order＆＃39;是一个保留关键字，因此请避免使用关键字作为表名。 This Link已经在此处报告了类似的错误。因此，请更改表名称的名称＆＃39;订单＆＃39;任何其他人或给它一个引用，例如＆＃39; Order＆＃39;。

DELIMITER //
CREATE TRIGGER OrderDetail_AFTER_INSERT AFTER INSERT ON OrderDetail
FOR EACH ROW
BEGIN
  UPDATE `Order` SET total = total + NEW.subtotal WHERE id = NEW.orderid;
END;
//
DELIMITER ;

插入更新后的MySQL触发器
