直入正题吧：首先创建一张 students 表

create table students(
    id int primary key auto_increment,
    age int,
    name varchar(20),
    city varchar(20)
) character set utf8;

insert into students values(null, 22, ‘赵四‘, ‘杭州‘);
insert into students values(null, 16, ‘刘能‘, ‘上海‘);
insert into students values(null, 20, ‘谢广坤‘, ‘深圳‘);
insert into students values(null, 21, ‘刘美兰‘, ‘北京‘);
insert into students values(null, 20, ‘宋晓峰‘, ‘湖北‘);
insert into students values(null, 21, ‘谢大脚‘, ‘江苏‘);
insert into students values(null, 20, ‘苏玉红‘, ‘天津‘);
insert into students values(null, 21, ‘陈艳兰‘, ‘云南‘);
