1，查看自己安装的mysql的编码
2、查看Mysql支持的编码
3、查看数据库编码
4、查看数据表编码（show create table user \G;）
5、修改my.ini文件来修改编码：加上default-character-set=字符集（utf8.gbk.gb2312等）
6、命令行修改：alter database da_name default character set "charset' ；或 set names 'charset'；或alter database testdb character set utf8;
8、查看数据库服务和客户端字符集：
9、Linux系统下的修改：<??http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">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"gbk';
6)查看现在的编码
mysql> status;
Server characterset: latin1
Db characterset: gbk
Client characterset: gbk
Conn. characterset: gbk
7)导入我们转换成gbk后的文件
mysql> source base_user_gbk.sql;
