以orcl实例下，person表为例：

1.登录mysql：

mysql安装路径下，bin目录，打开命令窗口，输入mysql -u用户名 -p密码;

2.显示所有实例，show databases;

3.进入orcl实例，use orcl;

4.显示person表字段信息，desc person;

5.修改字段描述，alter table person change pid PID int(11) not null;

6.修改表名，alter table person rename to people;

7.查，select *from person;

8.增，insert into person(name,age,birthday,salary) values(‘Ming‘,11,‘1999-01-01‘,1000);

9.改，update person set name = ‘XiaoLi‘ where pid = 11;

10.删，delete from person where pid = 10;

11.数，select count(1), age from person group by age;

12.排序，select name,salary from person order by salary asc;

select name,salary from person order by salary desc;
