我想在 MySQL 中创建一个触发器。我运行以下命令:
mysql> delimiter //
mysql> CREATE TRIGGER before_insert_money BEFORE INSERT ON money
-> FOR EACH ROW
-> BEGIN
-> UPDATE accounts SET balance=10.0;
-> END;
-> //
Query OK, 0 rows affected (0.19 sec)
但是当我在 phpmyadmin 中运行 SQL 时,我得到了这个错误:
#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 4
这里有什么问题?如何创建触发器?
