当时没有想到是字符集的问题，就纳闷怎么查不进去，而且insert的时候，后面的中文没有显示出来，这就奇怪了。
去图形界面用navicat插入，也是不成功。然后就去查看字符集，
- mysql> show variables like '%character%';
- +--------------------------+----------------------------+
- | Variable_name | Value |
- +--------------------------+----------------------------+
- | character_set_client | utf8 |
- | character_set_connection | utf8 |
- | character_set_database | latin1 |
- | character_set_filesystem | binary |
- | character_set_results | utf8 |
- | character_set_server | latin1 |
- | character_set_system | utf8 |
- | character_sets_dir | /usr/share/mysql/charsets/ |
- +--------------------------+----------------------------+
结果字符集不是UTF8 而是latin1
原因：
我的MySQL5.6.25是通过rpm包安装的，应该是MySQL默认的字符集是latin1。如果是编译安装可以再cmake的时候指定字符集。
解决办法：
我先把表的字符集修改为utf8，图形界面和命令行都一样
ALTER TABLE t1 DEFAULT CHARACTER SET=utf8;
再查看的时候就可以显示了。
为了以后的表都可以正常显示中文，我直接把MySQL数据库实例的字符集修改为utf8
5.6之前的版本是
default-character-set=utf8
5.6版本修改字符集的参数是
character-set-server=utf8
直接vi /etc/my.cnf 文件添加到[mysqld] 下面，重启MySQL即可
- [mysqld]
- socket = /mysqldata/mysql/mysql.sock
- character-set-server=utf8
再去数据库里面查看如下：
- mysql> show variables like '%character%';
- +--------------------------+----------------------------+
- | Variable_name | Value |
- +--------------------------+----------------------------+
- | character_set_client | utf8 |
- | character_set_connection | utf8 |
- | character_set_database | utf8 |
- | character_set_filesystem | binary |
- | character_set_results | utf8 |
- | character_set_server | utf8 |
- | character_set_system | utf8 |
- | character_sets_dir | /usr/share/mysql/charsets/ |
- +--------------------------+----------------------------+
查看表记录显示:
- mysql> select * from t1;
- +----+---------+--------+
- | id | name | class |
- +----+---------+--------+
- | 1 | zhangyi | 一班 |
- | 2 | zhanger | 二班 |
- | 4 | zhangsi | 四班 |
- +----+---------+--------+
- 3 rows in set (0.00 sec)
