一、查看 MySQL 数据库服务器和数据库字符集。
mysql show variables like %char%
+————————–+————————————-+——
| Variable_name | Value |……
+————————–+————————————-+——
| character_set_client | utf8 |…… — 客户端字符集
| character_set_connection | utf8 |……
| character_set_database | utf8 |…… — 数据库字符集
| character_set_filesystem | binary |……
| character_set_results | utf8 |……
| character_set_server | utf8 |…… — 服务器字符集
| character_set_system | utf8 |……
| character_sets_dir | D:\MySQL Server 5.0\share\charsets\ |……
+————————–+————————————-+——
二、查看 MySQL 数据表(table)的字符集。
mysql show table status from sqlstudy_db like %countries%
+———–+——–+———+————+——+—————–+——
| Name | Engine | Version | Row_format | Rows | Collation |……
+———–+——–+———+————+——+—————–+——
| countries | InnoDB | 10 | Compact | 11 | utf8_general_ci |……
+———–+——–+———+————+——+—————–+——
三、查看 MySQL 数据列(column)的字符集。
mysql show full columns from countries;
+———————-+————-+—————–+——–
| Field | Type | Collation | …….
+———————-+————-+—————–+——–
| countries_id | int(11) | NULL | …….
| countries_name | varchar(64) | utf8_general_ci | …….
| countries_iso_code_2 | char(2) | utf8_general_ci | …….
| countries_iso_code_3 | char(3) | utf8_general_ci | …….
| address_format_id | int(11) | NULL | …….
+———————-+————-+—————–+——–
四、查看当前安装的 MySQL 所支持的字符集。
mysql show charset;
mysql show char set;
+———-+—————————–+———————+——–+

以上查看 MySQL 字符集命令,适用于 Windows。
Liunx 下修改 MySQL 字符集:
1. 查找 MySQL 的 cnf 文件的位置
find / -iname *.cnf -print
/usr/share/mysql/my-innodb-heavy-4G.cnf
/usr/share/mysql/my-large.cnf
/usr/share/mysql/my-small.cnf
/usr/share/mysql/my-medium.cnf
/usr/share/mysql/my-huge.cnf
/usr/share/texmf/web2c/texmf.cnf
/usr/share/texmf/web2c/mktex.cnf
/usr/share/texmf/web2c/fmtutil.cnf
/usr/share/texmf/tex/xmltex/xmltexfmtutil.cnf
/usr/share/texmf/tex/jadetex/jadefmtutil.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-4G.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-large.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-small.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-medium.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-huge.cnf
2. 拷贝 small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf 其中的一个到 /etc 下,命名为 my.cnf
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
3. 修改 my.cnf
vi /etc/my.cnf
在 [client] 下添加
default-character-set=utf8
在 [mysqld] 下添加
default-character-set=utf8
4. 重新启动 MySQL
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
Shutting down MySQL [确定]
Starting MySQL. [确定]
[root@bogon ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.1.22-rc-community-log MySQL Community Edition (GPL)
Type help; or \h for help. Type \c to clear the buffer.
其他的一些设置方法:
修改的字符集
use mydb
mysql alter database mydb character set utf-8;
创建数据库指定数据库的字符集
mysql create database mydb character set utf-8;
通过配置文件修改:
修改 /var/lib/mysql/mydb/db.opt
default-character-set=latin1
default-collation=latin1_swedish_ci
为
default-character-set=utf8
default-collation=utf8_general_ci
重起 MySQL:
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
通过 MySQL 命令行修改:
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)
