SQLServer2005新增序列功能的几个函数：ROW_NUMBER, RANK, DENSE_RANK, and NTILE

SELECT ProductID, Name, Price,
ROW_NUMBER() OVER(ORDER BY Price DESC) As PriceRank
FROM Products

SELECT c.Name, o.DateOrdered, tab.TotalOrderAmount,
ROW_NUMBER() OVER (PARTITION BY c.CustomerID ORDER BY TotalOrderAmount DESC) AS BestCustomer
FROM vwTotalAmountBilledPerOrder AS tab
INNER JOIN Orders AS o ON
o.OrderID = tab.OrderID
INNER JOIN Customers AS c ON
c.CustomerID = o.CustomerID

SELECT c.Name, o.DateOrdered, tab.TotalOrderAmount,
RANK() OVER (ORDER BY TotalOrderAmount DESC) AS BestCustomer
FROM vwTotalAmountBilledPerOrder AS tab
INNER JOIN Orders AS o ON
o.OrderID = tab.OrderID
INNER JOIN Customers AS c ON
c.CustomerID = o.CustomerID

SELECT ProductID, Name, Price, NTILE(4) OVER (ORDER BY Price DESC) as Quartile

FROM Produts
