SSRS 报告的 SQL Server 查询

Question

I have a table like this:

period    balance
-----------------
1         100
1         200
2         300
2         400  
3         400
3         500

I need to show this in a SSRS report; I would like to calculate sum if max period as column maximum, then sum based on the second max which is 2

3      2       1
-------------------
900    700     300

Thanks

Answer 1

I'm assuming you want to sort the periods by the sum value of each period?

If so, the easiest way is to simply sum your data by period.

SELECT period, SUM(balance) as periodBalance GROUP BY period

This will give you

period periodBalance
     1 300
     2 700
     3 900

Them in SSRS use a matrix and set the column group to group on period. finally set the column group sort to periodBalance ZA assuming you want to see the largest periodBalance first. If you just want to see the periods in reverse order then just set the sort to period ZA
