分頁存儲(chǔ)過程在好多文章中都有介紹過；本篇是不久前寫的一個(gè)分頁存儲(chǔ)過程，可應(yīng)用于SQL Server 2005上面，感興趣的朋友可以研究下，希望本文對(duì)你學(xué)習(xí)存儲(chǔ)過程有所幫助

這是不久前寫的一個(gè)分頁存儲(chǔ)過程，可應(yīng)用于SQL Server 2005上面：

復(fù)制代碼代碼如下:

 
if object_ID('[proc_SelectForPager]') is not null 
Drop Procedure [proc_SelectForPager] 
Go 
Create Proc proc_SelectForPager 
( 
@Sql varchar(max) , 
@Order varchar(4000) , 
@CurrentPage int , 
@PageSize int, 
@TotalCount int output 
) 
As 
/*Andy 2012-2-28 */ 
Declare @Exec_sql nvarchar(max) 
Set @Exec_sql='Set @TotalCount=(Select Count(1) From ('+@Sql+') As a)' 
Exec sp_executesql @Exec_sql,N'@TotalCount int output',@TotalCount output 
Set @Order=isnull(' Order by '+nullif(@Order,''),' Order By getdate()') 
if @CurrentPage=1 /*經(jīng)常會(huì)調(diào)用第1頁，這里做特殊處理，少一層子查詢*/ 
Set @Exec_sql=' 
;With CTE_Exec As 
( 
'+@Sql+' 
) 
Select Top(@pagesize) *,row_number() Over('+@Order+') As r From CTE_Exec Order By r 
' 
Else 
Set @Exec_sql=' 
;With CTE_Exec As 
( 
Select *,row_number() Over('+@Order+') As r From ('+@Sql+') As a 
) 
Select * From CTE_Exec Where r Between (@CurrentPage-1)*@pagesize+1 And @CurrentPage*@pagesize Order By r 
' 
Exec sp_executesql @Exec_sql,N'@CurrentPage int,@PageSize int',@CurrentPage,@PageSize 
Go 

調(diào)用方法：
1.單表：

復(fù)制代碼代碼如下:

 
Exec proc_SelectForPager @Sql = 'Select * from contacts a where a.ContactType=1', -- varchar(max) 
@Order = '', -- varchar(4000) 
@CurrentPage = 3, -- int 
@PageSize = 20, -- int 
@TotalCount = 0 -- int 

2.多表聯(lián)接：

復(fù)制代碼代碼如下:

 
Exec proc_SelectForPager @Sql = 
'Select a.Staff,a.OU,b.FName+b.FName as Name 
from staffOUHIST a 
inner join Staff b on b.ID=a.Staff and a.ExpiryDate=''30001231'' 
', -- varchar(max) 
@Order = '', -- varchar(4000) 
@CurrentPage = 3, -- int 
@PageSize = 20, -- int 
@TotalCount = 0 -- int 

注：在@Sql 中不能使用CTE。
