Hi Guys! In last weekend I was thinking let's write something on SQL Server database. So I was just thinking which topics should I covered or on which topics should I write...... thinking......thinking...., suddenly I got an idea lets write on some common questions or something which will more efficient during ours interviews or related to our project. So I've decided let's write on "How to skip N to M records during table record selection?", I think this is very common question., So let's see how to do that in SQL Server database.
Scenario: Suppose that, I've a table ABC and this table having following records,
Table: ABC
Id Name Address
1 Peter XYZ
2 John PQR
3 Scott B'u CBT
4 Allen 123-TPO
5 Belly 986-PYT
So here question is Do we select 2 rows starting from 3rd row?
Solution: I think the most elegant is to use the ROW_NUMBER function to resolve this problem.

WITH NumberedMyTable AS
(
SELECT
Id,
Value,
ROW_NUMBER() OVER (ORDER BY Id) AS RowNumber
FROM
MyTable
)
SELECT
Id,
Value
FROM
NumberedMyTable
WHERE
RowNumber BETWEEN @From AND @To
So in this way you can resolve this problem. Please feel free comment forany assistance or query.
