设置数据库字符集

Windows系统下面

一、更改配置文件my.ini
1、中止MySQL服务：net stop mysql
2、在MySQL的安装目录下找到my.ini，如果没有就把my-medium.ini复制为一个my.ini即可
3、打开my.ini以后，在[client]和[mysqld]下面均加上default-character-set=utf8，保存并关闭（mysqld中增加如果出错，可以试 character-set-server=utf8）
4、启动MySQL服务：net start mysql
二、使用命令行方式

mysql> SET character_set_client = utf8 ;  
mysql> SET character_set_connection = utf8 ;   
mysql> SET character_set_database = utf8 ;   
mysql> SET character_set_results = utf8 ;    
mysql> SET character_set_server = utf8 ;   
mysql> SET collation_connection = utf8 ;  
mysql> SET collation_database = utf8 ;   
mysql> SET collation_server = utf8 ;
