Question

我正在尝试在表上设置触发器，以将行的内容复制到另一个表中。

我有以下内容：

CREATE TRIGGER story_deleted BEFORE DELETE ON stories 
  FOR EACH ROW BEGIN
    INSERT INTO stories_backup SET story_id = OLD.story_id;  
  END;

但是这会返回以下错误：

1064 - 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 '' at line 3

我无法解决我出错的地方。有什么想法吗？

Answer 1

尝试更改分隔符

DELIMITER $$

CREATE TRIGGER story_deleted BEFORE DELETE ON stories  
  FOR EACH ROW
  BEGIN 
    INSERT INTO stories_backup SET story_id = OLD.story_id;   
  END $$

DELIMITER ;

并且就您的权限而言，运行此查询

SHOW GRANTS;

如果没有SUPER，你可以

请求您的DBA为您添加该权限
让您的DBA为您创建触发器

mySQL触发器返回错误
