sql 分頁查詢

---sql 分頁查詢
create table Paging(
ID  int null,
Num int null)
declare @i as int
set @i=1000
while @i<10000
begin
insert into Paging
select @i,floor(rand()*20)
set @i=@i+1
end
select * from Paging
--每頁10條,取第800頁數據
--方法一：Order by
Select Top (40-31+1)  * From Paging Where ID in (Select Top 8010 ID From Paging Order by ID  ) Order by ID Desc
--方法二：not in/top
select top 10 * from Paging where id not in (select top 8000 id from Paging order by id) order by id
--方法三：not exists 
select top 10 * from Paging where not exists 
(select 1 from (select top 8000 id from Paging order by id)a1 where a1.id=Paging.id) order by id
--方法四:max/top
select top 10 * from Paging where id>(select max(id) from (select top 8000 id from Paging order by id)a1) order by id
--方法五：row_number()
select * from (select row_number()over(order by id)rownumber,* from Paging)a1 where rownumber>30 and rownumber<41
--方法六:row_number() 變體，不基於已有字段產生記錄序號，先按條件篩選以及排好序，再在結果集上給一常量列用於產生記錄序號
select * from (select row_number()over(order by id)rownumber,* from (select top 40 * from Paging where 1=1 order by id)a
)b where rownumber>30


exec pag_1 201
--分頁，每頁20條數據存儲過程
create proc pag_1
@i int
as
begin
select ID,Num from (select ROW_NUMBER()over(order by ID) nume,* from paging)a
where a.nume>(@i-1)*20 and a.nume<(@i*20)+1
end
