分页存储过程在好多文章中都有介绍过；本篇是不久前写的一个分页存储过程，可应用于SQL Server 2005上面，感兴趣的朋友可以研究下，希望本文对你学习存储过程有所帮助
这是不久前写的一个分页存储过程，可应用于SQL Server 2005上面：
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 /*经常会调用第1页，这里做特殊处理，少一层子查询*/
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
调用方法：
1.单表：
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.多表联接：
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。
