create proc pagination
 @pageRecordNum int,@currentPageNum int
as
 declare @recNum varchar(10),@pageNum varchar(10)
 set @recNum=convert(varchar(10),@pageRecordNum)
 set @pageNum=convert(varchar(10),(@currentPageNum-1)*@pageRecordNum)
 exec ('select top '+@recNum+' * from users where userid not in(select top '+@pageNum+' userid from users)')
