登录mysql -- >
进入相应的数据库 --->
输入：show variables like '%char%';
得道：
+--------------------------+--------------------------------------+
| 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 | F:\SoftWare\mysql5.5\share\charsets\ |
+--------------------------+--------------------------------------+
如果出现上述情况需要更改编码数据库，有两种方法：第一种一次搞定（如果表已经存在，需要重新创建），第二种只对当前连接有效，断开连接，回复原来状态
方法1： alter database 数据库名 charset utf8;
方法2： set character_set_database = utf8;
在使用：show variables like '%char%'；
