MysqL学习1,查看MysqL字符集设置
 

MysqL> show variables like 'collation_%';
+----------------------+-----------------+
| variable_name         | value            |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database    | utf8_general_ci |
| collation_server      | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.02 sec)
MysqL> show variables like 'character_set_%';
+--------------------------+----------------------------+
| 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/ |

MysqL学习2,MysqL字符编码与字符集的其它设置方法：

MysqL学习修改数据库的字符集
 

MysqL>use mydb
MysqL>alter database mydb character set utf-8;
 

MysqL学习创建数据库指定数据库的字符集
 

MysqL>create database mydb character set utf-8;

MysqL学习通过配置文件修改MysqL字符编码：
修改/var/lib/MysqL/mydb/db.opt
 

default-character-set=latin1
default-collation=latin1_swedish_ci
 

MysqL学习为
 

default-character-set=utf8
default-collation=utf8_general_ci
 

MysqL学习重启MysqL数据库：
 

[root@jbxue ~]# /etc/rc.d/init.d/MysqL restart

MysqL学习1)、通过MySQL命令行修改字符编码：
 

MysqL> set character_set_client=utf8;
query ok,0 rows affected (0.00 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_results=utf8;
query ok,0 rows affected (0.00 sec)
MysqL> set character_set_server=utf8;
query ok,0 rows affected (0.00 sec)
MysqL> set character_set_system=utf8;
query ok,0 rows affected (0.01 sec)
MysqL> set collation_connection=utf8;
query ok,0 rows affected (0.01 sec)
MysqL> set collation_database=utf8;
query ok,0 rows affected (0.01 sec)
MysqL> set collation_server=utf8;
query ok,0 rows affected (0.01 sec)

MysqL学习查看MysqL字符编码：
 

MysqL> show variables like 'character_set_%';
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.03 sec)
MysqL> show variables like 'collation_%';
+----------------------+-----------------+
| variable_name         | value            |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database    | utf8_general_ci |
| collation_server      | utf8_general_ci |
+----------------------+-----------------+
