load data infile 导入数据 中文显示乱码 解决方法
各种字符参数统一为utf8
SET character_set_client = utf8 ;
SET character_set_connection = utf8 ;
SET character_set_database = utf8 ;
SET character_set_results = utf8 ;
SET character_set_server = utf8 ;
SET collation_connection = utf8 ;
SET collation_database = utf8 ;
SET collation_server = utf8 ;
– 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。
