mysql字符编码是版本4.1引入的,支持多国语言,而且一些特性已经超过了其他的数据库系统。

我们可以在MySQL Command Line Client 下输入如下命令查看mysql的字符集

mysql> SHOW CHARACTER SET;

字符集支持(Character Set Support)有两个方面：字符集(Character set)和排序方式(Collation)。对于字符集的支持细化到四个层次: 服务器(server)，数据库(database)，数据表(table)和连接(connection)。

查看系统的字符集和排序方式的设定可以通过下面的两条命令：

mysql> SHOW VARIABLES LIKE 'character_set_%';

+--------------------------+-------------------------------------------+

| Variable_name            | Value                                     |

+--------------------------+-------------------------------------------+

| character_set_client     | latin1                                    |

| character_set_connection | latin1                                    |

| character_set_database   | latin1                                    |

| character_set_filesystem | binary                                    |

| character_set_results    | latin1                                    |

| character_set_server     | latin1                                    |

| character_set_system     | utf8                                      |

| character_sets_dir       | D:\MySQL\MySQL Server 5.0\share\charsets\ |

+--------------------------+-------------------------------------------+

mysql> SHOW VARIABLES LIKE 'collation_%';

+----------------------+-------------------+

| Variable_name        | Value             |

+----------------------+-------------------+

| collation_connection | latin1_swedish_ci |

| collation_database   | latin1_swedish_ci |

| collation_server     | latin1_swedish_ci |
