mysql - mySQL Trigger returns error

Question

I am trying to set up a trigger on a table to copy the contents of a row into another table.

I have the following:

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

This returns the following error though:

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

I can't work out where I'm going wrong with this. Any ideas?

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 ;

就您的权限而言，运行此查询

SHOW GRANTS;

如果 SUPER 不存在，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
