插入触发器之前的mysql

Question

我尝试创建以下触发器:

DELIMITER $$

CREATE trigger insert_processor
BEFORE INSERT ON tbl
FOR EACH ROW BEGIN

set new.val = trim(new.val);
set new.val2 = upper(new.val);

END$$

失败并显示以下错误消息

#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 8

可能是什么原因？

MySql服务器版本:5.1.40-community

客户端:phpMyAdmin 3.3.8

Answer 1

看看您的 phpmyadmin 版本中是否有 DILIMITER 字段，就在 SQL 编辑器下方。在那里设置分隔符，例如 - '$$'，然后编写此 SQL 代码 -

CREATE trigger insert_processor
BEFORE INSERT ON tbl
FOR EACH ROW BEGIN

set new.val = trim(new.val);
set new.val2 = upper(new.val);

END$$
