sql分頁查詢

方法一、

alter procedure  PagedQuery
(
 @size int,     頁大小
 @pageIndex int     頁索引
) 
as 
select top (@size) * from class where classid not in (select top(@size*@pageIndex) classid from class order by classid)
go

exec PagedQuery 3,0

方法二、

create procedure  PagedQuery2
(
 @size int,
 @pageIndex int
) 
as 
select a.* from (select *,ROW_NUMBER() over(order by classid asc) as RowNo from class) as a 
where RowNo between (@size* @pageIndex+1)   and  (@size* (@pageIndex+1))
go
exec PagedQuery2 4,0

(注：分組分頁查詢，row_number() OVER (PARTITION BY COL1 ORDER BY COL2) 表示根據COL1分組，在分組內部根據 COL2排序，而此函數計算的值就表示每組內部排序後的順序編號（組內連續的唯一的))
