解决MySQL下把结果导出到文件权限不足问题
select ... into outfile '..' 权限问题
在MySQL下把结果导出到文件，总是权限不足。
mysql> select * into outfile 'e:/mysql/i0812.txt' fields terminated by '|' lines
terminated by '\r\n' from samtest;
ERROR 1 (HY000): Can't create/write to file 'e:\mysql\i0812.txt' (Errcode: 2)
解决方法，赋权：
mysql> grant file on *.* to root@localhost;
