我有这个问题:
Available Total Usage
7000.0 7021.9
7000.0 -15000.00
7000.0 -7700.85
我想创建新列以按降序对两列进行求和。我希望的结果是
Available Total Usage Total
7000.0 7021.9 -700.85+(-15000.00) = -15700.85
7000.0 -15000.00 7000+(-7700.85) = -700.85
7000.0 -7700.85 7000
我该怎么做?
答案 0 :(得分:0)
试试这个:
with cte as(select Available, [Total Usage], Available+[Total Usage] as Total from <table>)
select * from CTE order y Total
