如何在Sql Server精簡版SELECT語句中複製Rank函數？

Question

它看起來不像SQL Server Compact Edition支持RANK（）函數。 （請參閱函數（SQL Server Compact Edition） at http://msdn.microsoft.com/en-us/library/ms174077(SQL.90).aspx）。

我該如何複製SQL Server Compact Edition SELECT語句中的RANK（）函數。

（請使用Northwind.sdf任何樣本select語句，因爲它是唯一一個我可以與SQL Server 2005 Management Studio中打開）

Answer 1

SELECT x.[Product Name], x.[Unit Price], COUNT(y.[Unit Price]) Rank 
FROM Products x, Products y 
WHERE x.[Unit Price] < y.[Unit Price] or (x.[Unit Price]=y.[Unit Price] and x.[Product Name] = y.[Product Name]) 
GROUP BY x.[Product Name], x.[Unit Price] 
ORDER BY x.[Unit Price] DESC, x.[Product Name] DESC;

用途：

SELECT x.[Product Name], x.[Unit Price], COUNT(y.[Unit Price]) AS Rank 
    FROM Products x 
    JOIN Products y ON x.[Unit Price] < y.[Unit Price] 
        OR ( x.[Unit Price]=y.[Unit Price] 
         AND x.[Product Name] = y.[Product Name]) 
GROUP BY x.[Product Name], x.[Unit Price] 
ORDER BY x.[Unit Price] DESC, x.[Product Name] DESC; 

以前：

SELECT y.id, 
     (SELECT COUNT(*) 
     FROM TABLE x 
     WHERE x.id <= y.id) AS rank 
    FROM TABLE y
