由于我对同一个客户有相同的BillingDate，我想根据匹配的BillingDate来计算消耗量。这应该给我以下内容：

CITY - PARKS/6TH AVE BMX PARK   2013-04-29 00:00:00.000 30
CITY - PARKS/6TH AVE BMX PARK   2013-05-30 00:00:00.000 19500
CITY - PARKS/6TH AVE BMX PARK   2013-06-28 00:00:00.000 42100
CITY - FIRE STATION #3  2012-11-27 00:00:00.000 8900

依旧......

我发布了一个类似的问题，但我真的没有得到我想要的东西。谢谢SQL专家。

如果我没有遗漏某些东西

select Customers, BillingDate, sum(Consumption)
from Table1
group by Customers, BillingDate

Answer 2

它类似于：

Select
Customers, BillingDate, sum(Consumption)
from [Table]
group by Customers, BillingDate
