合并列然后识别源列

Question

我希望有此表，将每两个列的数据合并到1（Material1 +材料2，数量1 + Quantity2，时间1 +时间2）和另一行，以确定查询材质是否是材质1或材质2。

输入数据：

所需的输出：

我曾尝试：

SELECT Material1 as Material 
FROM [test] 
UNION all 
SELECT Material2 
FROM [test] 

SELECT [Quantity1] as Quantity 
FROM [test] 
Union all 
Select Quantity2 
FROM [test] 
ORDER BY Quantity1 

，但它原来是两个表..

Answer 1

也许这样的事情？

select 'Material1' as Name 
     ,Material1 as Material 
     ,Quantity1 as Quantity 
     ,Time1 as [Time] 
from [test] 

union all 

select 'Material2' as Name 
     ,Material2 as Material 
     ,Quantity2 as Quantity 
     ,Time2 as [Time] 
from [test]
