数据库-mysql中文显示问题

一：在mysql 下面查看带中文的记录显示乱码

mysql> select * from role;
+----+------+
| id | name |
+----+------+
|  1 | ??   |
+----+------+
1 row in set (0.00 sec)

解决办法：

1）查看编码：show variables like 'char%';

character_set_results    | latin1 显示为拉丁文

2）设置编码：set character_set_results=utf8;

mysql> select * from role;
+----+------+
| id | name |
+----+------+
|  1 | ??   |
+----+------+
1 row in set (0.00 sec)

mysql> show variables like 'char%';

| Variable_name            | Value                      |

| character_set_client     | latin1                     |
| character_set_connection | latin1                     |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | latin1                     |
| character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
