Question

我有一个查询，检查无效发票以及是否重新投标。我们不允许在那里重新招标“quicksales”，如果快速通知无效，我的查询就会变得混乱。我想做的是，如果“快速销售”已经无效......在重新标记的字段显示“QuickSale”中，它也不应该检查发票是否已被重新保留，因为我们不允许它。我的查询在下面，我们将搜索t1.Register_Transaction_Type列以查看“Quick”是否为类型。所有其他交易都很好。

SELECT        
  t1.Store_Number, 
  t1.Invoice_Number, 
  t1.Invoice_Date, 
  t1.Vehicle_Tag, 
  t1.Void_Reason, 
  vt1.Invoice_Total, 
  t2.Invoice_Number AS [New Invoice #], 
  t2.Vehicle_Tag AS [Vehicle Tag], 
  t2.Invoice_Total AS [New Invoice Total], 
  CASE 
    WHEN t2.Vehicle_Tag IS NULL THEN 'NO'
    WHEN t1.register_transaction_type = 'QUICK' THEN 'Quicksale'
    ELSE 'YES'
  END AS [Re-tendered?], 
  User_Tb.User_Name, 
  t1.Register_Transaction_Type
FROM            
  Invoice_Tb AS t1 
  INNER JOIN Employee_Tb 
    ON t1.Void_Employee_Tax_Payer_Id = Employee_Tb.Tax_Payer_Id 
  INNER JOIN User_Tb 
    ON Employee_Tb.User_Id = User_Tb.User_Id 
  LEFT OUTER JOIN Invoice_Tb AS t2 
    ON t1.Vehicle_Tag = t2.Vehicle_Tag AND 
       t2.Void_Flag = 'n' AND 
       t2.Invoice_Date >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0) AND
       t2.Invoice_Date < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)
WHERE        
  (t1.Void_Flag = 'y') AND 
  (t1.Invoice_Date >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) 
  AND (t1.Invoice_Date < DATEADD(day, DATEDIFF(day, 0, GETDATE()),0)) 
  AND (t1.Store_Number = '2')
ORDER BY t1.Store_Number, t1.Invoice_Date

下面是我得到的一个例子：你可以看到它只是倾销发票而没有链接到......

Answer 1

-- code
CASE
    WHEN t2.Vehicle_Tag IS NULL THEN 'NO'
    WHEN [COLUMN] IS [CONDITION]
    -- ...
    ELSE 'YES'
END AS [Re-tendered?]

Answer 2

你要这个吗？

CASE
  WHEN t1.Register_Transaction_Type = 'Quick' THEN 'QuickSale'
  WHEN t2.Vehicle_Tag IS NULL THEN 'NO'
  ELSE 'YES'
  END AS [Re-tendered?]

如果您可以提供一个显示您所考虑的逻辑的小表，这可能会有所帮助，即对于列值的这种组合，我想要这种输出值。
