hi friends,

a quick reference of paging i found here :

http://4guysfromrolla.com/webtech/062899-1.shtml

CREATE PROCEDURE sp_PagedItems
(
@Page int,
@RecsPerPage int
)
AS

-- We don't want to return the # of rows inserted
-- into our temporary table, so turn NOCOUNT ON
SET NOCOUNT ON


--Create a temporary table
CREATE TABLE #TempItems
(
ID int IDENTITY,
OrderNo numeric(9)

)


-- Insert the rows from tblItems into the temp. table
INSERT INTO #TempItems (OrderNo)
SELECT OrderNo FROM OrderNo ORDER BY OrderNo

-- Find out the first and last record we want
DECLARE @FirstRec int, @LastRec int
SELECT @FirstRec = (@Page - 1) * @RecsPerPage
SELECT @LastRec = (@Page * @RecsPerPage + 1)

-- Now, return the set of paged records, plus, an indiciation of we
-- have more records or not!
SELECT *,
MoreRecords =
(
SELECT COUNT(*)
FROM #TempItems TI
WHERE TI.ID >= @LastRec
)
FROM #TempItems
WHERE ID > @FirstRec AND ID < @LastRec


-- Turn NOCOUNT back OFF
SET NOCOUNT OFF


GO
