如何从表中删除或选择具有特定行号的行？

我有一个关于 Microsoft SQL Server 2005 的问题。如何从具有特定行号的表中删除或选择行？

编辑：修改代码，使其更符合OP的意图

Declare @RowNum as INT
SET @RowNum = 15 ---Just for example

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 = @RowNum
 ORDER BY OrderDate
         ,OrderID;
