Mysql导出数据表到文件

/**
导出数据库的方法：
(1)OUTFILE 应该使用mysql的--secure-file-priv否则会出现：
[Err] 1290 - The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
那么，应该怎么找到--secure-file-priv呢？
1.在mysql命令行中，使用 show variables like '%secure%';
2. secure_file_priv         | C:\ProgramData\MySQL\MySQL Server 5.7\Uploads\ 
选择C:/ProgramData/MySQL/MySQL Server 5.7/Uploads/后边加上你的文件名。
注意:应该是'/'而不是'\'。
然后执行：
select * from employee into outfile "C:/a.txt" fields terminated by "," enclosed by '"'

 fields terminated by "," enclosed by '"'
**/

select * from employee into outfile "C:/ProgramData/MySQL/MySQL Server 5.7/Uploads/a3.txt" fields terminated by "," enclosed by '\n' LINES TERMINATED BY "\n";
