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;
