《Mysql入门mysql字符集查看与设置详解》要点： 注意,mysql 乱码的主要原因在于mysql 字符集设置不当的问题.MYSQL学习 收集了一些mysql 字符集的命令. 一、查看 mysql 数据库服务器和数据库字符集.
二、查看 mysql 数据表(table) 的字符集. +-----------+--------+---------+------------+------+-----------------+------ | 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.
四、查看当前安装的 mysql 所支持的字符集. 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 | +----------+-----------------------------+---------------------+--------+ 说明：以上查看 mysql 字符集命令,适用于 windows & linux.MYSQL学习 1,查找mysql的cnf文件的位置 find / -iname '*.cnf' -printMYSQL学习 /usr/share/mysql/my-innodb-heavy-4g.cnf 2,复制small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4g.cnf其中的一个到/etc下,命名为my.cnf 3,修改my.cnf default-character-set=utf8 在[mysqld]下添加 default-character-set=utf8 4,重新启动mysql shutting down mysql?? [ 确定 ] starting mysql.?? [ 确定 ] [root@jbxue ~]# mysql -u root -p enter password: welcome to the mysql monitor. commands end with ; or g. your mysql connection id is 1 server version: 5.1.22-rc-community-log mysql community edition (gpl) type 'help;' or 'h' for help. type 'c' to clear the buffer. 5,查看mysql字符集设置 +----------------------+-----------------+ | variable_name???????? | value??????????? | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database??? | utf8_general_ci | | collation_server????? | utf8_general_ci | +----------------------+-----------------+ 3 rows in set (0.02 sec) mysql> show variables like 'character_set_%'; +--------------------------+----------------------------+ | variable_name???????????? | value?????????????????????? | +--------------------------+----------------------------+ | character_set_client????? | utf8??????????????????????? | | character_set_connection | utf8??????????????????????? | | character_set_database??? | utf8??????????????????????? | | character_set_filesystem | binary????????????????????? | | character_set_results???? | utf8??????????????????????? | | character_set_server????? | utf8??????????????????????? | | character_set_system????? | utf8??????????????????????? | | character_sets_dir??????? | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.02 sec) ? 1),修改数据库的字符集 mysql>alter database mydb character set utf-8(utf8);
2),通过配置文件修改mysql字符集 default-character-set=latin1 default-collation=latin1_swedish_ci 为 default-character-set=utf8 default-collation=utf8_general_ci 3)、重启mysql数据库 4)mysql命令行修改字符集 query ok,0 rows affected (0.00 sec) mysql> set character_set_connection=utf8; query ok,0 rows affected (0.00 sec) mysql> set character_set_database=utf8; query ok,0 rows affected (0.00 sec) mysql> set character_set_results=utf8; query ok,0 rows affected (0.00 sec) mysql> set character_set_server=utf8; query ok,0 rows affected (0.00 sec) mysql> set character_set_system=utf8; query ok,0 rows affected (0.01 sec) mysql> set collation_connection=utf8; query ok,0 rows affected (0.01 sec) mysql> set collation_database=utf8; query ok,0 rows affected (0.01 sec) mysql> set collation_server=utf8; query ok,0 rows affected (0.01 sec) 5),查看mysql字符集 +--------------------------+----------------------------+ | variable_name???????????? | value?????????????????????? | +--------------------------+----------------------------+ | character_set_client????? | utf8??????????????????????? | | character_set_connection | utf8??????????????????????? | | character_set_database??? | utf8??????????????????????? | | character_set_filesystem | binary????????????????????? | | character_set_results???? | utf8??????????????????????? | | character_set_server????? | utf8??????????????????????? | | character_set_system????? | utf8??????????????????????? | | character_sets_dir??????? | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.03 sec) mysql> show variables like 'collation_%'; +----------------------+-----------------+ | variable_name???????? | value??????????? | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database??? | utf8_general_ci | | collation_server????? | utf8_general_ci | +----------------------+-----------------+ 3 rows in set (0.04 sec) 欢迎参与《Mysql入门mysql字符集查看与设置详解》讨论，分享您的想法，编程之家PHP学院为您提供专业教程。 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
