从2表中选择2个不同的值

您好，我想选择与每个拍卖ID相关联的每个拍卖ID，其中status ='won'，并且每个拍卖ID的状态是'过期'，作为两个分隔列我的发言能够有人帮助请，第一列将被调用赢了，第二个过期从2表中选择2个不同的值

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

期望的结果：

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

你想要在这些列中显示哪些数据？ – Szymon

一次拍卖会赢得和过期吗？ –

没有任何拍卖可以赢得或过期不是两个 – user3287068

如果你想要的结果是这样的：

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

然后，你可以使用此查询：

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

但如果你想要的结果是这样的：

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

然后这个查询会做：

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

第三次尝试。要得到这样的：

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

使用此查询：

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

这些例子似乎在好的方式，所以让我解释一下我在做什么，我正在做一个计数拍卖Bidding.Status ='won'和另一个计数在哪里拍卖.Status ='已过期'，我要在图中显示此结果 – user3287068

@ user3287068我添加了另一个版本。我想这可能是你以后的事情。 – jpw

现在感谢它的工作 – user3287068

拍卖就不可能取得胜利，并在同一时间，让你不到期吨需要有例如：AuctionId 1：韩元：120214，过期050214？

那么让我们来想象这是可能的：

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

我想要显示的是具有关联BidID的所有拍卖ID，其状态='wON'AS WON，最后是所有拍卖。id这是他自己的状态='已过期' – user3287068

-1

试试这个..

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的选民，但是在目前的格式下，这是不合法的TSQL。 –

@大卫没关系，如果我写了一些错误的东西，那么我应该被投票。 –

你可以尝试这样的事情，它不是确切只是一个概述

*** 

    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
