mysql 乱码的解决办法_MySQL

显示字符集，并将相应字符集更改为utf8

show variables like "%char%";

+--------------------------+---------------+
| 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 |

例如

SET character_set_client='utf8';
SET character_set_connection='utf8';
SET character_set_results='utf8'

创建表时：

CREATE TABLE video_author (
        sid bigint(11) NOT NULL AUTO_INCREMENT,
        nick varchar(64) NOT NULL,
        url' varchar(128) NOT NULL,
        video_type set('dota', 'lol', 'hearthstone'),
        PRIMARY KEY (sid),
        KEY index_name (nick)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

如果使用python的mysql连接，还需要在连接时设置charset，例如：

self.conn=MySQLdb.connect(host="127.0.0.1",user="root", passwd="000", db="app_db",port=3306,charset='utf8')
