通用分页存储过程(SQL Server 2005)

这是不久前写的一个分页存储过程，可应用于SQL Server 2005上面：

代码如下

复制代码

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：

代码如下

复制代码

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 -- int2.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。
