Hi,
Can some one help me to complete this query.
My requirement is to convert the existing stored proc(given below) to one that allows dynamic paging as well as sorting(sql server 2005). I gave a try but invein. I am running out of time.

Existing procedure:

ALTER PROCEDURE [dbo].[spGetAllItems]
@condition varchar(7500),
@ModelId int =0,
@CategoryId int=0,
@SourcingType int=0,
@StartRow as int = 1,
@StopRow as int = 100000
AS
declare @erow int
declare @Cond varchar(255)

select @Cond=''

if @CategoryId<>0
select @Cond= ' and tbItemMaster.Category=' + cast(@CategoryId as varchar)
if @SourcingType<>0
select @Cond= ' and tbItemMaster.SourcingType=' + cast(@SourcingType as varchar)

if @StopRow=-1
select @StopRow=60
set @erow=@StartRow + @StopRow

exec('Declare @t_table table
