說明:分頁顯示在實際業務中經常需要用到,其SQL語句分兩種

--方法一:跳過多少行,選中多少行
--每頁n條,選擇第m頁--n=2 m=3
--select top(n) * from 表 where 主鍵 not in (select top(m-1)*n 主鍵 from 表);
select  * from UserInfo
select top(2) * from UserInfo where Empid not in (select top((3-1)*2) EmpId from UserInfo);
--方法二,通過rowNumber函數,但是只能當作臨時表
select * from
 
(select * ,ROW_NUMBER() over (order by EmpId) as num from UserInfo) as T
where T.num between (3-1)*2+1 and 3*2;
--over開窗函數的的另一個用法
select top(2) * ,AVG(StuAge) over() as 平均年齡 from UserInfo;
