按SQL中的求和和计数的多个值分组相同的范围

Question

我想在同一个范围内按行分组不同的冒号。例如：

Amount1 |  Amount2 
------------------------ 
20,00 |  30,00 
35,00 |  32,00 
12,00 |  51,00 
101,00 |  100,00 

这里的结果应该是;

Range |TotalAmount1 |TotalAmount2 | CountAmount1 | CountAmount2 | RateOfCountAmount1  
----------------------------------------------------------------------------- 
0-50  | 67,00  | 62,00  | 3   | 1   | %75 
50-100 | 0,00  | 151,00  | 0   | 2   | %0 
100+  | 101,00  | 0,00  | 1   | 0   | %25 
Total | 168,00  | 213,00  | 4   | 3   | %100

可以查询这样

;with cte as (
select case when amount1 < 50 then '0-50' 
      when amount1 between 50.01 and 100 then '50-100' 
      when amount1 > 100 then '100+' end as rngamt1, 
     case when amount2 < 50 then '0-50' 
      when amount2 between 5.01 and 100 then '50-100' 
      when amount2 > 100 then '100+' end as rngamt2, 
       * from amounts 
), cte2 as (select coalesce(rngamt1, rngamt2) as [Range], isnull(a.TotalAmount1,0) as TotalAmount1, isnull(b.TotalAmount2, 0) as TotalAmount2, isnull(a.TotalCount1 , 0) as TotalCount1, isnull(b.TotalCount2, 0) as Totalcount2 from 
(select rngamt1, sum(amount1) TotalAmount1, count(amount1) TotalCount1 from cte c 
group by rngamt1) a 
full join 
(select rngamt2, sum(amount2) TotalAmount2, count(amount2) TotalCount2 from cte c 
group by rngamt2) b 
on a.rngamt1 = b.rngamt2 
) 
select *, (TotalCount1 * 100)/sum(TotalCount1) over() as RateCount1 
from cte2 
union 
select 'Total' as [Range], sum(TotalAmount1) as TotalAmount1, sum(totalAmount2) as TotalAmount2,  
    sum(TotalCount1) as TotalCount1, sum(Totalcount2) as TotalCount2, (sum(TotalCount1)*100)/Sum(TotalCount1) as RateCount1 from cte2
