如何计算特定范围内的交易数量

Question

任何人都可以帮助我们使用TSQL计算去年销售额在此范围内的交易数量。我不知道如何填充该范围并将其与我在数据库中的销售总额相关联

0.01- 5.00,
5.001 -10.00,
10.01 - 15.00 

我试过使用下面的代码，

SELECT COUNT (*) as Nooftransactions, Floor (Amount)/5 As Range, Convert(Varchar(max), (5*Floor(Linetotal/5))) +'0.01' + '-' + Convert(Varchar(max), (5*floor(Linetotal/5) +5))) + '0.00' as Rangesplit 
Group by Amount,Floor (Amount)/5 , Convert(Varchar(max), (5*Floor(Linetotal/5))) +'0.01' + '-' + Convert(Varchar(max), (5*floor(Linetotal/5) +5))) + '0.00' 
Order Amount 

Answer 1

有点

select ranges.lo, ranges.hi,
    count(*) as [number of transactions]
from transactions t
join ( 
  values (0.01, 5.00), (5.001, 10.00), (10.01, 15.00) 
) ranges(lo, hi)
on t.value between ranges.lo and ranges.hi
group by ranges.lo, ranges.hi
order by ranges.lo;

根据实际表格结构进行调整。
