SQL Server 2005通用分页存储过程及多表联接应用
这是不久前写的一个分页存储过程，可应用于SQL Server 2005上面： <BR><div class="codetitle"><span><a data="72246" class="copybut" id="copybut72246"><U>复制代码</U></a></span> 代码如下:</div><div class="codebody" id="code72246"> <BR>if object_ID('') is not null <BR>Drop Procedure <BR>Go <BR>Create Proc proc_SelectForPager <BR>( <BR>@Sql varchar(max) , <BR>@Order varchar(4000) , <BR>@CurrentPage int , <BR>@PageSize int, <BR>@TotalCount int output <BR>) <BR>As <BR>/*Andy 2012-2-28 */ <BR>Declare @Exec_sql nvarchar(max) <BR>Set @Exec_sql='Set @TotalCount=(Select Count(1) From ('+@Sql+') As a)' <BR>Exec sp_executesql @Exec_sql,N'@TotalCount int output',@TotalCount output <BR>Set @Order=isnull(' Order by '+nullif(@Order,''),' Order By getdate()') <BR>if @CurrentPage=1 /*经常会调用第1页，这里做特殊处理，少一层子查询*/ <BR>Set @Exec_sql=' <BR>;With CTE_Exec As <BR>( <BR>'+@Sql+' <BR>) <BR>Select Top(@pagesize) *,row_number() Over('+@Order+') As r From CTE_Exec Order By r <BR>' <BR>Else <BR>Set @Exec_sql=' <BR>;With CTE_Exec As <BR>( <BR>Select *,row_number() Over('+@Order+') As r From ('+@Sql+') As a <BR>) <BR>Select * From CTE_Exec Where r Between (@CurrentPage-1)*@pagesize+1 And @CurrentPage*@pagesize Order By r <BR>' <BR>Exec sp_executesql @Exec_sql,N'@CurrentPage int,@PageSize int',@CurrentPage,@PageSize <BR>Go <BR></div> <BR><STRONG>调用方法</STRONG>： <BR><STRONG>1.单表</STRONG>： <BR><div class="codetitle"><span><a data="63960" class="copybut" id="copybut63960"><U>复制代码</U></a></span> 代码如下:</div><div class="codebody" id="code63960"> <BR>Exec proc_SelectForPager @Sql = 'Select * from contacts a where a.ContactType=1', -- varchar(max) <BR>@Order = '', -- varchar(4000) <BR>@CurrentPage = 3, -- int <BR>@PageSize = 20, -- int <BR>@TotalCount = 0 -- int <BR></div> <BR><STRONG>2.多表联接</STRONG>： <BR><div class="codetitle"><span><a data="41934" class="copybut" id="copybut41934"><U>复制代码</U></a></span> 代码如下:</div><div class="codebody" id="code41934"> <BR>Exec proc_SelectForPager @Sql = <BR>'Select a.Staff,a.OU,b.FName+b.FName as Name <BR>from staffOUHIST a <BR>inner join Staff b on b.ID=a.Staff and a.ExpiryDate=''30001231'' <BR>', -- varchar(max) <BR>@Order = '', -- varchar(4000) <BR>@CurrentPage = 3, -- int <BR>@PageSize = 20, -- int <BR>@TotalCount = 0 -- int <BR></div> <BR><STRONG>注</STRONG>：在@Sql 中不能使用CTE。
