我需要的uniq的代码的总和。

Answer 1

简单GROUP BY和总和将给出结果：

Select Unique_code, Deal_no, Sum(Amount) as Amount 
    from yourtable 
group by Unique_code, Deal_no 

可以如下，如果你有多个列查询：

Select * from (
    Select *, Sum_Amount = Sum(Amount) over(partition by Unique_Code, Deal_No), 
     RowN = Row_Number() over(partition by Unique_code, Deal_No order by [option] desc) 
     from yourtable) a 
    Where a.RowN = 1
