Question

使用InnoDB在MySQL 5.5.9上运行。

我创建了以下触发器：

CREATE TRIGGER TRIGGER_Products_Insert
AFTER INSERT ON Products

FOR EACH ROW
BEGIN
UPDATE Products
SET current = 0
WHERE   id = new.id
    AND current = 1
    AND autonumber <> new.autonumber
END;

MySQLWorkbench在最后一行显示语法错误，执行此操作会引发以下错误

错误代码：1064。您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第11行的“END”附近使用正确的语法

我的错误在哪里？

Answer 2

您在;关键字前缺少END：

CREATE TRIGGER TRIGGER_Products_Insert
AFTER INSERT ON Products

FOR EACH ROW
BEGIN
UPDATE Products
SET current = 0
WHERE   id = new.id
    AND current = 1
    AND autonumber <> new.autonumber;
END;
