1 mysql> set character_set_client=utf8;

3 mysql> set character_set_database=utf8;
4 mysql> set character_set_results=utf8;
5 mysql> set character_set_server=utf8;
6 mysql> set character_set_system=utf8;

8 mysql> set collation_database=utf8;
9 mysql> set collation_server=utf8;

類似這樣的即可。這裏只是改變了當前鏈接的配置。

如果是程序鏈接數據庫發生了亂碼，建議修改數據庫的配置文件。
如果輸入命令，應該是：

1 ---1.修改數據庫字符集
2 alter database mini default character set = gb2312; 
3 ----2.創建數據庫設置字符集
4 create database mydb character set gb2312;

如何設置server characterset和db characterset
