合併列然後識別源列

Question

我希望有此表，將每兩個列的數據合併到1（Material1 +材料2，數量1 + Quantity2，時間1 +時間2）和另一行，以確定查詢材質是否是材質1或材質2。

輸入數據：

所需的輸出：

我曾嘗試：

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 

，但它原來是兩個表..

Answer 1

也許這樣的事情？

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]
