Let us first set up the environment for performing the demonstration.We will populate 100 records to a tblPagingExperiment table

--Drop the table tblPagingExperiment if it exists
IF OBJECT_ID('tblPagingExperiment','U') IS NOT NULL BEGIN
DROP TABLE tblPagingExperiment
END
GO

-- Create the table
Create Table tblPagingExperiment (
[Person ID] Int Identity
,[Person Name] Varchar(100)
,Age Int
,DOB Datetime
,Address Varchar(100)
)
GO

-- Populate 100 data to the table
Insert into tblPagingExperiment
Select
'Person Name' + CAST(Number AS VARCHAR)
, Number
,DATEADD(D,Number, '1900-01-01')
,'Address' + CAST(Number AS VARCHAR)
From master..spt_values
Where Type = 'p'
And Number Between 1 and 100

-- Project the records
Select *
From tblPagingExperiment


Paging using Sql Server 2005 Row_Number approach

-- Variable to hold the offset value
Declare @RowSkip As int
-- Variable to hold the fetch value
Declare @RowFetch As int

--Set the value of rows to skip
Set @RowSkip = 10
--Set the value of rows to fetch
Set @RowFetch = 20

;With Cte As
(
Select
rn=ROW_NUMBER()
Over(Order by (Select 1) /* generating some dummy column*/ )
,*
From tblPagingExperiment
)
-- Fetch the records from 11 to 30
Select
[Person ID]
,[Person Name]
,Age
,DOB
,Address
From Cte
Where rn Between (@RowSkip+1)And (@RowSkip+ @RowFetch)

/* Result */
Person ID Person Name Age DOB Address
11 Person Name11 11 1900-01-12 00:00:00.000 Address11
