整蠱SQL如果UPDATE

Question

我有這樣的UPDATE SQL：

UPDATE o 
SET  HolidayPay = lob.AllowHolidayPay , 
     AppreciationPay = lob.AllowAppreciationPay 
FROM Orders AS o 
     INNER JOIN LineofBusiness AS lob ON o.LineofBusinessID = lob.LineofBusinessID 
WHERE o.StatusID != 156 -- ALL ORDERS THAT ARE NOT CLOSED 
     AND o.TempOrDirect = 'T' 
GO 

我需要在WHERE子句做的不僅僅是使用statusID。需要發生的是，如果statusID = 156，那麼它還需要檢查stageID的值。所以如果statusID = 156，但stageID = 6，那沒關係。如果statusID仍然是156，但stageID是任何其他值，則觀察！=部分。

在此先感謝！

Answer 1

使用

(o.StatusID != 156 OR (o.StageID=6 and o.StatusID=156)) 

Answer 2

於是級ID = 6或StatusID！= 156？

WHERE (o.StatusID != 156 
     OR stageID = 6) 
    AND o.TempOrDirect = 'T'
