SELECT *, 
     SelectBidID, DATENAME(mm, Date) AS Month 
FROM BID 
WHERE (Status = 'Won') 

Answer 1

試試這個

SELECT *, SelectBidID, DATENAME(mm, Date) AS Month, 
     Case [Status] 
      When 'expired' Then 'sucessfull' 
      When 'unsold' Then 'unsucessfull' 
      --Else 'Unknown' 
     End As [Status] 
FROM BID 
WHERE [Status] = 'expired' 
     OR [Status] = 'unsold' 

Answer 2

WITH Unsold AS 
     (SELECT *, 
      Select BidID, DATENAME(mm, Date) AS Month 
      ,Status As U_Status 
    FROM BID 
    WHERE (Status = 'unsold') 
    ),Expired AS 
     (SELECT *, 
      SelectBidID, DATENAME(mm, Date) AS Month 
      ,Status as E_Status 
    FROM BID 
    WHERE (Status = 'expired') 
    ) 


    Select s.*, s.U_Status, e.E_Status from Unsold s 
    INNER JOIN Expired e ON s.SelectBidID =e.SelectBidID
