我希望查询此表,将每两列的数据合并为1(Material1 + Material2,Quantity1 + Quantity2,Time1 + Time2),另一行用于标识材料(如果它是Material1或Material2)
输入数据:
期望的输出:
我试过了:
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
但事实证明是在两个表格中。
答案 0 :(得分:1)
也许是这样的?
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]
