SQL Server 2005通用分页存储过程及多表联接应用

2019-01-03 MsSQL 前端之家

前端之家收集整理的这篇文章主要介绍了SQL Server 2005通用分页存储过程及多表联接应用，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

这是不久前写的一个分页存储过程，可应用于sql Server 2005上面：
<div class="codetitle"><a style="CURSOR: pointer" data="95197" class="copybut" id="copybut95197" onclick="doCopy('code95197')"> 代码如下:

<div class="codebody" id="code95197">
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 CTEExec Order By r
'
Else
Set @Execsql='
;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
：
<div class="codetitle"><a style="CURSOR: pointer" data="86911" class="copybut" id="copybut86911" onclick="doCopy('code86911')"> 代码如下:

<div class="codebody" id="code86911">
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

：
<div class="codetitle">@L_403_2@ 代码如下:

<div class="codebody" id="code64885">
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''
',-- int
@TotalCount = 0 -- int
