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/ | +--------------------------+----------------------------+

• 修改數據庫的字符集 mysql>use databaseName mysql>alter database databaseName character set utf-8;
• 在建立數據庫時指定數據庫的字符集 mysql>create database databaseName character set utf-8;

• 再說下linux下設置mysql大小寫敏感的問題和設置默認字體集的問題 vi /etc/my.cnf 在[mysqld] 下加入 lower_case_table_names=1//不區分大小寫，0爲要區分。 default-character-set=utf8//設置服務端的字符集爲*** 在[client]下添加 default-character-set=utf8
