SQL 服务器，使用行号

Question

我有以下查询，其中 returns 已售商品列表按售出数量排序。销量最高的商品排在第 1 位，后面的商品按升序排列。

SELECT  
      RANK() OVER (ORDER BY SUM(Quantity) DESC,       
      SUM(LineTotalInDefaultCurrency) DESC) AS SalesRank,
      P.Name ,SUM(Quantity) as UnitsSold ,
      SUM(LineTotalInDefaultCurrency) as RevenueDefaultCurrency, 
      sf.ProductId
FROM 
      SalesFact sf 
INNER JOIN 
      Product p ON sf.ProductId = p.ProductId 
WHERE 
      Dttm >= '2014-08-08' AND Dttm <= '2017-08-09' GROUP BY sf.ProductId, p.Name

它returns一个像这样的结果列表

SalesRank   Name                                UnitsSold   RevenueDefaultCurrency  ProductId   
1           Energy Saving Dryer Balls           1230        6429.58         1086381

8           Vacuum Post Motor Filter            10          20.99           1562181

我正在尝试将行号添加到结果查询中，这样我的结果看起来像

Row SalesRank   Name                                UnitsSold   RevenueDefaultCurrency  ProductId   
1   1           Energy Saving Dryer Balls           1230        6429.58         1086381     
2   2           Universal Dishwasher Cutlery Basket 654         4700.64         1107301     
3   3           Limescale and Detergent Remover     361         4106.00         664212      
4   4           Universal Extendable Oven Shelf     364         3885.77         655005  
5   5           2500 Watt Fan Oven Element          157         1532.72         1019719 
6   6           Filter Vacuum Bags NVM-1CH          273         2320.88         479302  
7   7           Universal Dishwasher Cutlery Basket 81          1954.66         511673  
8   8           Ice Cube Tray                       10          20.99           655045
9   8           Vacuum Filter - Pack of 2           10          20.99           470556
10  8           Vacuum Post Motor Filter            10          20.99           1562181

我一直在尝试使用 ROW_NUMBER() 来实现这一点。目前我已经修改了我的查询以包含 ROW_NUMBER()，所以我现在有

SELECT  
     RANK() OVER (ORDER BY SUM(Quantity) DESC, 
     SUM(LineTotalInDefaultCurrency) DESC) AS SalesRank,
     p.Name ,SUM(Quantity) as UnitsSold ,
     SUM(LineTotalInDefaultCurrency) as RevenueDefaultCurrency,      
     sf.ProductId,
     ROW_NUMBER() OVER(ORDER BY COUNT(sf.ProductId) DESC, sf.ProductId) AS [row]
 FROM 
     SalesFact sf INNER JOIN Product p ON sf.ProductId = p.ProductId 
 WHERE 
     Dttm >= '2014-08-08' AND Dttm <= '2017-08-09' 
 GROUP BY 
     sf.ProductId, p.Name

但是我无法正确排序。如果我添加 ORDER BY 行，那么 SalesRank 是乱序的，如果我添加 ORDER by SalesRank，那么结果不会按 Row

排序

我希望这是有道理的。谁能建议我如何实现上述结果集。谢谢

Answer 1

从您想要的结果集来看，您似乎想要为您的 row_number 设置相同的订单，但在相同的排名中，按名称的附加订单：

with cte as
(
SELECT  
   p.Name ,
   SUM(Quantity) as UnitsSold ,
   SUM(LineTotalInDefaultCurrency) as RevenueDefaultCurrency,  
   sf.ProductId
FROM 
   SalesFact sf 
INNER JOIN 
    Product p ON sf.ProductId = p.ProductId 
WHERE 
    Dttm >= '2014-08-08' AND Dttm <= '2017-08-09' 
GROUP BY 
    sf.ProductId, p.Name
)

select *,    
       RANK() OVER (ORDER BY UnitsSold DESC, RevenueDefaultCurrency DESC) AS SalesRank,
       ROW_NUMBER() OVER (ORDER BY UnitsSold DESC, RevenueDefaultCurrency desc, Name ) AS [row] 
from cte;

Answer 2

我认为你的 row 定义有误：

SELECT ROW_NUMBER() OVER (ORDER BY SUM(Quantity) DESC, 
                                   SUM(LineTotalInDefaultCurrency) DESC
                         ) AS row,
       RANK() OVER (ORDER BY SUM(Quantity) DESC, 
                             SUM(LineTotalInDefaultCurrency) DESC
                   ) AS SalesRank,
       p.Name, SUM(Quantity) as UnitsSold ,
       SUM(LineTotalInDefaultCurrency) as RevenueDefaultCurrency,      
       sf.ProductId,   
FROM SalesFact sf INNER JOIN
     Product p
     ON sf.ProductId = p.ProductId 
WHERE Dttm >= '2014-08-08' AND Dttm <= '2017-08-09' 
GROUP BY sf.ProductId, p.Name
ORDER BY [row];
