Question

I have data sorted by dates:

e.g.
Region – Date – Count
East – 2012/01/01 – 5
West – 2012/01/01 – 2
East – 2012/01/06 – 3
South – 2012/01/07 – 3
etc

I’m trying to create a sum of the Counts, grouped by date groups relative to today. So for example

Assuming today was 2012/01/07:

• Yesterday is defined to be from Today – 1 to today (non-inclusive of
  today)
• Week is defined to be from Today – 7 to today (non-inclusive of
  today)
• Month is defined to be from Today – 28 to today (non-inclusive
  of today)

The output in the matrix for the sample data would be:

As a bonus, ideally I’d have a 5th column that’s for “On Demand” Start and End date range for the user to input.

I think the key is to add an EXPR in the Column Group’s Group On property but I don’t know what the Expression should be.

Any help would be great!

Personally I think I would prefer to attack it in the SQL query. So for example

SELECT 
 CASE WHEN DATEDIFF(day, GETDATE(), DateColumn) = 0 THEN SomeColumn ELSE 0 END cToday
 CASE WHEN DATEDIFF(day, GETDATE(), DateColumn) = 1 THEN SomeColumn ELSE 0 END cYesterday
 CASE WHEN DATEDIFF(day, GETDATE(), DateColumn) > 0 AND 
           DATEDIFF(day, GETDATE(), DateColumn) < 8 THEN SomeColumn ELSE 0 END cWeek
 CASE WHEN DATEDIFF(day, GETDATE(), DateColumn) > 0 THEN SomeColumn ELSE 0 END cMonth
FROM 
 SomeTable
WHERE 
 DateColumn > DATEADD(day, -28, GETDATE())

Otherwise you could use a similar approach inside SSRS
