Row Offset in SQL Server

Question

Is there any way in SQL Server to get the results starting at a given offset? For example, in another type of SQL database, it\'s possible to do:

SELECT * FR

You should be careful when using the ROW_NUMBER() OVER (ORDER BY) statement as performance is quite poor. Same goes for using Common Table Expressions with ROW_NUMBER() that is even worse. I'm using the following snippet that has proven to be slightly faster than using a table variable with an identity to provide the page number.

DECLARE @Offset INT = 120000
DECLARE @Limit INT = 10

DECLARE @ROWCOUNT INT = @Offset+@Limit
SET ROWCOUNT @ROWCOUNT

SELECT * FROM MyTable INTO #ResultSet
WHERE MyTable.Type = 1

SELECT * FROM
(
    SELECT *, ROW_NUMBER() OVER(ORDER BY SortConst ASC) As RowNumber FROM
    (
        SELECT *, 1 As SortConst FROM #ResultSet
    ) AS ResultSet
) AS Page
WHERE RowNumber BETWEEN @Offset AND @ROWCOUNT

DROP TABLE #ResultSet
