在使用SSH框架时候,使用getHibernateTemplate().update() 更新数据出现 java.sql.BatchUpdateException: 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 key=nu

在使用SSH框架时候,使用getHibernateTemplate().update() 更新数据出现

java.sql.BatchUpdateException: 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 'key=null, isok=0, nicheng='

更新数据出错,找了很久没找到原因。后面突然想到以前用了mysql的关键字 order 做为商品的订单表名字,导致过错误,会不会也是这个原因? 看看报错位置,看见near 'key,是不是key不能做为字段名字呢?于是改之,换成其他英文来表示,重启tomcat,执行操作,OK,成功。

原因就是把mysql关键字用做表字段了,导致了错误,解决就是,修改字段名字,不要用 关键字做表名或者字段名:

order key 不要做为mysql数据库的表名或者字段

还有其他很多关键字如下:
