mysql从一个库的一个表中导出select部分内容的数据，将其导入到另外一个库的同结构的表中

首先查询mysql 导出指定的路径，使用命令

    show variables like '%secure%'; 

比如我的查询结果为

Variable_name 　　    Value
secure_auth 　　　　  ON
secure_file_priv 　　   /var/lib/mysql-files/

那么应该使用路径 /var/lib/mysql-files/

例如：

SELECT a.dic_id, a.`name`, a.`value`, a.state, a.order_num FROM (
SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_level'
UNION SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_4'
UNION SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_2'
UNION SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_5'
UNION SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_11'
UNION SELECT dic_id, `name`, `value`, state, order_num FROM tbl_dict_item WHERE dic_id ='res_6') a
INTO OUTFILE '/var/lib/mysql-files/aa.sql';

导入使用命令：

load data local infile "/var/lib/mysql-files/aa.sql" into table tbl_dict_item character set utf8;
