從2表中選擇2個不同的值

您好，我想選擇與每個拍賣ID相關聯的每個拍賣ID，其中status ='won'，並且每個拍賣ID的狀態是'過期'，作爲兩個分隔列我的發言能夠有人幫助請，第一列將被調用贏了，第二個過期從2表中選擇2個不同的值

SELECT 
     Auction.AuctionID, 
     DATENAME(mm, BID.Date) AS Month 
FROM 
     BID INNER JOIN Auction ON BID.AuctionID = Auction.AuctionID 
WHERE   
     BID.Status = 'Won' 
ORDER BY Month

期望的結果：

AuctionID Month       Won Expired 
----------- ------------------------------ ---- ------- 
1   January       32 22 
2   March       10 22 
3   April       0  2

你想要在這些列中顯示哪些數據？ – Szymon

一次拍賣會贏得和過期嗎？ –

沒有任何拍賣可以贏得或過期不是兩個 – user3287068

如果你想要的結果是這樣的：

AuctionID Month       Won Expired 
----------- ------------------------------ ---- ------- 
1   January      Won NULL 
2   January      Won NULL 
3   January      NULL Expired

然後，你可以使用此查詢：

SELECT   
    A.AuctionID, 
    DATENAME(mm, B.Date) AS Month, 
    CASE Status WHEN 'Won' THEN 'Won' ELSE NULL END AS Won, 
    CASE Status WHEN 'Expired' THEN 'Expired' ELSE NULL END AS Expired 
FROM BID b 
INNER JOIN Auction a ON B.AuctionID = A.AuctionID 
ORDER BY Month, AuctionID

但如果你想要的結果是這樣的：

AuctionID Month       Status 
----------- ------------------------------ -------------------- 
1   January      Won 
2   February      Won 
3   January      Expired

然後這個查詢會做：

SELECT   
    A.AuctionID, 
    DATENAME(mm, B.Date) AS Month, 
    Status 
FROM BID b 
INNER JOIN Auction a ON B.AuctionID = A.AuctionID 
ORDER BY Status Desc, Month DESC, AuctionID

第三次嘗試。要得到這樣的：

Month       Won   Expired 
------------------------------ ----------- ----------- 
January      1   1 
February      1   0

使用此查詢：

SELECT 
    DATENAME(mm, B.Date) AS Month, 
    SUM(CASE WHEN Status = 'Won' THEN 1 ELSE 0 END) AS Won, 
    SUM(CASE WHEN Status = 'Expired' THEN 1 ELSE 0 END) AS Expired 
FROM BID b 
INNER JOIN Auction a ON B.AuctionID = A.AuctionID 
GROUP BY DATENAME(mm, B.Date), B.Date 
ORDER BY b.Date

這些例子似乎在好的方式，所以讓我解釋一下我在做什麼，我正在做一個計數拍賣Bidding.Status ='won'和另一個計數在哪裏拍賣.Status ='已過期'，我要在圖中顯示此結果 – user3287068

@ user3287068我添加了另一個版本。我想這可能是你以後的事情。 – jpw

現在感謝它的工作 – user3287068

拍賣就不可能取得勝利，並在同一時間，讓你不到期噸需要有例如：AuctionId 1：韓元：120214，過期050214？

那麼讓我們來想象這是可能的：

with p as (
    SELECT Auction.AuctionID, DATENAME(mm, BID.Date) AS Month 
    FROM BID 
    INNER JOIN Auction ON BID.AuctionID = Auction.AuctionID) 

select AuctionId, max(Won), Max(Expired) 
from 
(
    select AuctionId, Month as Won, null as Expired from p 
    WHERE (BID.Status = 'Won') 
    union 
    select AuctionId, null, Month from p 
    WHERE (BID.Status = 'Expired') 
) z 
ORDER BY Won, Expired

我想要顯示的是具有關聯BidID的所有拍賣ID，其狀態='wON'AS WON，最後是所有拍賣。id這是他自己的狀態='已過期' – user3287068

-1

試試這個..

SELECT 
    Auction.AuctionID, 
    DATENAME(mm, BID.Date) AS Month, 
    CASE status 
    WHEN Won THEN Status As Won 
    WHEN Expired THEN Status As Expired 
    END 
FROM 
    BID INNER JOIN Auction ON BID.AuctionID = Auction.AuctionID 
ORDER BY Month

我不是down down的選民，但是在目前的格式下，這是不合法的TSQL。 –

@大衛沒關係，如果我寫了一些錯誤的東西，那麼我應該被投票。 –

你可以嘗試這樣的事情，它不是確切只是一個概述

*** 

    SELECT 
      Auction.AuctionID, 
      DATENAME(mm, b1.Date) AS Month, 
      COUNT(*) AS `Won`, 
      (SELECT count(*) from BID b2 WHERE DATENAME(mm, b1.Date) = DATENAME(mm, b2.Date))-COUNT(*) AS `EXPIRED` 
    FROM 
      BID b1 
      INNER JOIN Auction ON BID.AuctionID = Auction.AuctionID  
    WHERE   
      BID.Status = 'Won' 
    GROUP BY Month
