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。
