MySQL 乱码的根源是的 MySQL 字符集设置不当的问题,本文汇总了有关查看 MySQL 字符集的命令。包括查看 MySQL 数据库服务器字符集、查看 MySQL 数据库字符集,以及数据表和字段的字符集、当前安装的 MySQL 所支持的字符集等。

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;
+----------+-----------------------------+---------------------+--------+
