Paging with ROW_NUMBER() in TSQL

T-SQL: Paging with ROW_NUMBER()

In MSSQL 2000 we used to do paging either by dynamic sql or by some advanced
techniques like the example with rowcount.

In MSSQL 2005 with the introduction of ROW_NUMBER function life is a lot easier.

DECLARE @PageNum AS INT;
DECLARE @PageSize AS INT;
SET @PageNum = 2;
SET @PageSize = 10;

WITH OrdersRN AS
(
    SELECT ROW_NUMBER() OVER(ORDER BY OrderDate, OrderID) AS RowNum
          ,OrderID
          ,OrderDate
          ,CustomerID
          ,EmployeeID
      FROM dbo.Orders
)

SELECT *
  FROM OrdersRN
 WHERE RowNum BETWEEN (@PageNum - 1) * @PageSize + 1
                  AND @PageNum * @PageSize
 ORDER BY OrderDate
         ,OrderID;
