mysql的分页
select * from emp order by sal desc limit 3;--第一页，每页显示3条
select * from emp order by sal desc limit 4,3;
select * from emp order by sal desc limit 3,3;

-- 第一页用0表示
select * from emp order by sal desc ;
select * from emp order by sal desc limit 0,4;
select * from emp order by sal desc limit 1,4;
