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;

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;
