我有这个查询，我一直在努力，我试图找出如何根据[Unique_claim_identifying_number]字段求和[Charge Amount]字段。我只需要一个[Unique_claim_identifying_number]来显示[Charge Amount]的总和。我处于困境，任何额外的帮助将不胜感激。提前谢谢。

好的，所以，尝试使用这种结构..
select
a.[Unique_claim_identifying_number],
sum([Charge Amount]) as Total_Charge_Amount
from
(
...... place your query here.....
) a
group by
a.[Unique_claim_identifying_number]
