-- sql server 分頁查詢


--插入資料


declare @i int


set @i = 1


while (@i<10000)


begin 


insert into product values ('aaa'+cast(@i as varchar),@i,'2018-04-25')


set @i+=1;


end;


-- 方法一：order by 分頁sql，下面例子是每頁10條，取第31-40條資料。


select top (40-31+1) * from product where pid in (select top 40 pid from product order by pid ) order by pid desc;


-- 方法二：not in/top


select top 10 * from product where pid not in (select top 30 pid from product order by pid);


-- 方法三：not exists 


select top 10 * from product where not exists (select 1 from (select top 30 pid from product order by pid) p1 where p1.pid=product.pid) order by pid;


-- 方法四:max/top


select top 10 * from product where pid > (select max(pid) from (select top 30 pid from product order by pid)p1)order by pid;


-- 方法五：row_number()


select top 10 * from (select row_number() over(order by pid)rn,* from product) p1 where p1.rn>30;


select * from (select row_number() over(order by pid)rn,* from product) p1 where rn>30 and rn <41;


select * from (select row_number() over(order by pid) rn,* from product) p1 where rn between 31 and 40;


--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 pid)rn,* from (select top 40 * from product where 1=1 order by pid ) p1)p2 where rn>30;
