1.字符集就是字符和其编码的集合，查看数据库支持的字符集
show character set
2.查看服务端启动时默认的字符集
mysql> show variables like ‘character_set_%‘; +--------------------------+-------------------------------------------+ | Variable_name | Value | +--------------------------+-------------------------------------------+ | character_set_client | gbk | | character_set_connection | gbk | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | gbk | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | D:\MySQL\MySQL Server 5.5\share\charsets\ | +--------------------------+-------------------------------------------+
3.设置当前客户端会话字符集
set names utf8 or set character set ‘charset_name‘
4.在保存时指定字符集
create database student charser gb2312 -----数据库级粒度------- create table db_name(....)engine=MyISAM default charset=utf8 ----表级粒度------- col_name character set utf8 -----列级粒度------
5.设置全局粒度的默认字符集
set global character_set_server=utf8
