aspnetpager：其实只是起到用户界面的作用，记录了用户对页码的选择
并且传递给存储过程。如图：
//分页用到存储过程、不需要改变的存储过程
//只是以后要用到的
Create procedure jxytext_pagination @sqlstr nvarchar(4000), --查询字符串 @currentpage int, --第N页 @pagesize int --每页行数 as set nocount on declare @P1 int, --P1是游标的id @rowcount int exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output select ceiling(1.0*@rowcount/@pagesize) as TotalPages,@rowcount as TotalRows,@currentpage as CurPage set @currentpage=(@currentpage-1)*@pagesize+1 exec sp_cursorfetch @P1,16,@currentpage,@pagesize exec sp_cursorclose @P1 set nocount off GO
//真正要用到的存储过程
create procedure Pr_jxytest3 ( @sql varchar(1000) , @indexpage int, @pagesize int ) AS begin exec jxytext_pagination @sql,@indexpage,@pagesize end GO
