tsql - How to get N rows starting from row M from sorted table in T-SQL

There is a simple way to get top N rows from any table:

SELECT TOP 10 * FROM MyTable ORDER BY MyColumn

Is there any efficient way to query M rows starting from row N

For example,

Id Value
1    a
2    b
3    c
4    d
5    e
6    f

And query like this

SELECT [3,2] * FROM MyTable ORDER BY MyColumn /* hypothetical syntax */

queries 2 rows starting from 3d row, i.e 3d and 4th rows are returned.

UPDATE If you you are using SQL 2012 new syntax was added to make this really easy. See Implement paging (skip / take) functionality with this query

I guess the most elegant is to use the ROW_NUMBER function (available from MS SQL Server 2005):

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
