修改数据库全局编码格式：
1.命令行登录mysql
C:\Users\Administrator>mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.6.20 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
2. 查看mysql全局编码格式
mysql> show variables like 'character%';
+--------------------------+----------------------------------------------------
-----+
| Variable_name | Value
|
+--------------------------+----------------------------------------------------
-----+
| character_set_client | gbk
|
| character_set_connection | gbk
|
| character_set_database | latin1
|
| character_set_filesystem | binary
|
| character_set_results | gbk
|
| character_set_server | latin1
|
| character_set_system | utf8
|
| character_sets_dir | D:\Program Files\MySQL\MySQL Server 5.6\share\chars
ets\ |
3.把mysql的全局编码格式修改为utf8（character_set_filesystem=binary 不用修改）
mysql> set character_set_client = utf8;
Query OK, 0 rows affected (0.04 sec)
mysql> set character_set_connection = utf8
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_database = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_filesystem = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_results = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server = utf8;
Query OK, 0 rows affected (0.00 sec)
4.查看修改后的mysql全局编码格式
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 | D:\Program Files\MySQL\MySQL Server 5.6\share\chars
ets\ |
