查看 MySql 字符集

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; +----------+-----------------------------+---------------------+--------+ | Charset | Description | Default collation | Maxlen | +----------+-----------------------------+---------------------+--------+ | big5 | Big5 Traditional Chinese | big5_chinese_ci | 2 | | dec8 | DEC West European | dec8_swedish_ci | 1 | | cp850 | DOS West European | cp850_general_ci | 1 | | hp8 | HP West European | hp8_english_ci | 1 | | koi8r | KOI8-R Relcom Russian | koi8r_general_ci | 1 | | latin1 | cp1252 West European | latin1_swedish_ci | 1 | | latin2 | ISO 8859-2 Central European | latin2_general_ci | 1 | | swe7 | 7bit Swedish | swe7_swedish_ci | 1 | | ascii | US ASCII | ascii_general_ci | 1 | | ujis | EUC-JP Japanese | ujis_japanese_ci | 3 | | sjis | Shift-JIS Japanese | sjis_japanese_ci | 2 | | hebrew | ISO 8859-8 Hebrew | hebrew_general_ci | 1 | | tis620 | TIS620 Thai | tis620_thai_ci | 1 | | euckr | EUC-KR Korean | euckr_korean_ci | 2 | | koi8u | KOI8-U Ukrainian | koi8u_general_ci | 1 | | gb2312 | GB2312 Simplified Chinese | gb2312_chinese_ci | 2 | | greek | ISO 8859-7 Greek | greek_general_ci | 1 | | cp1250 | Windows Central European | cp1250_general_ci | 1 | | gbk | GBK Simplified Chinese | gbk_chinese_ci | 2 | | latin5 | ISO 8859-9 Turkish | latin5_turkish_ci | 1 | | armscii8 | ARMSCII-8 Armenian | armscii8_general_ci | 1 | | utf8 | UTF-8 Unicode | utf8_general_ci | 3 | | ucs2 | UCS-2 Unicode | ucs2_general_ci | 2 | | cp866 | DOS Russian | cp866_general_ci | 1 | | keybcs2 | DOS Kamenicky Czech-Slovak | keybcs2_general_ci | 1 | | macce | Mac Central European | macce_general_ci | 1 | | macroman | Mac West European | macroman_general_ci | 1 | | cp852 | DOS Central European | cp852_general_ci | 1 | | latin7 | ISO 8859-13 Baltic | latin7_general_ci | 1 | | cp1251 | Windows Cyrillic | cp1251_general_ci | 1 | | cp1256 | Windows Arabic | cp1256_general_ci | 1 | | cp1257 | Windows Baltic | cp1257_general_ci | 1 | | binary | Binary pseudo charset | binary | 1 | | geostd8 | GEOSTD8 Georgian | geostd8_general_ci | 1 | | cp932 | SJIS for Windows Japanese | cp932_japanese_ci | 2 | | eucjpms | UJIS for Windows Japanese | eucjpms_japanese_ci | 3 | +----------+-----------------------------+---------------------+--------+
