mysql总结

修改查看MYSQL字符集

• 查看mysql的字符集 >mysql> show variables like 'collation_%'; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci | +----------------------+-----------------+ 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/ | +--------------------------+----------------------------+

• 修改数据库的字符集 mysql>use databaseName mysql>alter database databaseName character set utf-8;
• 在建立数据库时指定数据库的字符集 mysql>create database databaseName character set utf-8;

• 再说下linux下设置mysql大小写敏感的问题和设置默认字体集的问题 vi /etc/my.cnf 在[mysqld] 下加入 lower_case_table_names=1//不区分大小写，0为要区分。 default-character-set=utf8//设置服务端的字符集为*** 在[client]下添加 default-character-set=utf8
