MySQL字符集设置 系统变量: – character_set_server:默认的内部操作字符集 – character_set_client:客户端来源数据使用的字符集 – character_set_connection:连接层字符集 – character_set_results:查询结果字符集 – character_set_database:当前选中数据库的默认字符集 – character_set_system:系统元数据(字段名等)字符集 – 还有以collation_开头的同上面对应的变量,用来描述字符序。 登陆MySQL数据库: C:/Users/duansf>mysql -u root -p Enter password: ****** Welcome to the MySQL monitor.

PHP程序在查询数据库之前,执行mysql_query(”set names utf8;”); 3.修改my.cnf,在[mysqld]中加入init-connect=”set names utf8” (对于超级用户连接该选项无效) 4. 启动mysqld 加入参数 –skip-character-set-client-handshake 忽略客户端字符集。 |
