mysql登陆 大写字母P是端口
C:\Program Files\MySQL\MySQL Server 5.6\bin>

mysql数据库远程:
grant all PRIVILEGES on *.* to 'root'@'192.168.0.%' identified by '3613571';
flush privileges;
(第一个*是数据库，第二个* 表示数据库中的表， win代表账户，%代表ip地址， win456 代表账户密码)

show databases;
use TD_OA;
show tables;
select * from user;
select * into outfile 'd:/test.xls' from 表名

create table aaa (ID INT(11),NAME varchar(255));
