分析
在MySQL中，我们可以为数据库、数据表和数据列分别设置编码格式，而且，在指定了编码格式的情况下，数据列的编码格式优先于数据表，数据表的编码格式优先于数据列，在没有指定编码格式的情况下，数据列继承数据表的编码格式，数据表继承数据库的编码格式——但是继承是以时序为前提的，例如，数据表继承的是在创建该表前数据库的编码格式，在一个数据表已经存在的情况下，修改该数据表所在数据库的编码格式并不会导致该数据表原有编码格式的改变。
如果单独执行和整体source文件执行都报错，那么就需检查一下数据库的编码、数据表的编码、sql_mode参数等细节，
查看数据库编码： show variables like 'char%';
查看数据表字段编码： show full columns from XX表名;
查出来如果不是UTF-8的，用MYSQL命令修改，如：
SET character_set_server = utf8; -----更改mysql服务器的编码为utf8
SET character_set_connection = utf8; -----更改数据库连接的编码为utf8
SET character_set_database = utf8; -----更改数据库编码为utf8

若是客户端查询乱码，则可以配置：
