mysql 修改编码失败怎么办
时间:2020-11-02 09:16
mysql修改编码失败的解决办法就是在连接url后加上代码“?useUnicode=true&characterEncoding=UTF-8”即可。 推荐:《mysql视频教程》 mysql 修改编码不成功解决办法 问题描述: 改为UTF8之后,重新进入mysql,它又自动改回latin1 有个方法很简单,在连接url后加上如下代码即可: 特别注意,两个属性之间一定要用&符号的转义符,且不能带空格,否则会报错。 例子如下 hibernate.cfg.xml配置文件: ================================= 1 修改数据库级 a. 临时更改: mysql>SET GLOBAL character_set_database=utf8; b. 永久更改: 改了服务器级就可以了 2.修改表级 更改了后永久生效 3.修改列级 修改示例: 更改了后永久生效 4.更改连接字符集 a. 临时更改: mysql> set names utf8; b. 永久更改: 修改my.ini文件 (linux 为my.cnf) 从my.ini下手 linux 下修改这里容易遇到问题,出错后请参考http://blog.csdn.net/zhongdajiajiao/article/details/51698845 以上就是mysql 修改编码失败怎么办的详细内容,更多请关注gxlsystem.com其它相关文章!?useUnicode=true&characterEncoding=UTF-8
