確定記錄是否在SQL Server的兩個不同列上使用OR條件激活

Question

我面臨一個棘手的問題，因爲我的表有兩個不同的列，這兩個列決定記錄是否處於活動狀態。 （由於同一個數據庫一次又一次的變化，兩個不同列，當然不是我自己。）

該字段是bit鍵入數據庫中。任何人都可以建議一個將從表中獲取記錄的查詢。

ex。 SELECT * FROM產品（isActive = 0或isCancelled = 1）

Answer 1

不活動：

select * from product where isActive = 0 or isCancelled =1 

活躍

select * from product where isActive = 1 and isCancelled =0 

Answer 2

我覺得這裏是寫這個查詢

select * from product where isActive = 1 and isCancelled = 0 -- Active records 
select * from product where not (isActive = 1 and isCancelled = 0) -- Inactive records 

Answer 3

好方法我會選擇計算值：

select *, (isActive = 1 and isCancelled = 0) as active 
from product 

或更好，但創建一個視圖來隱藏這個醜陋：

create view complete_product as 
select *, (isActive = 1 and isCancelled = 0) as active 
from product
