bitscn.com说到底mysql 乱码的根源是的 mysql 字符集设置不当的问题。
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                                |...... www.jbxue.com  | 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            | .......  +----------------------+-------------+-----------------+--------  mysql字符集查看与设置详解mysql字符集设置详解有关mysql字符集设定的知识总结(图文)mysql字符集设置详解
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 |  +----------+-----------------------------+---------------------+--------+  以上查看 mysql 字符集命令，适用于 windows & linux。bitscn.com
