Question

I have SQL Server 2005 Reporting Services. I need to create a report with number of columns that is defined during runtime.

I have a DB table with content like the following:

Person           Date             Val
----------------------------------------------
Person1          2012-01-03       3
Person2          2012-02-11       5
Person1          2012-02-17       7
Person2          2012-01-19       2
Person2          2012-01-15       4

I have to create a Report like this:

Person           Jan 2012         Feb 2012
----------------------------------------------
Person1          3                7
Person2          6                5

In other words, for every Person I have to make sum of all his Value fields for a given month, and put the sum into column corresponding to the month. In the example above I have 6 for Person2 during month Jan 2012 – this is sum of the values 2 (on 2012-01-19) and 4 (on 2012-01-15).

Thus, in design time I do not know the date range covered by that my table. I should detect it, to build array of months covered by the date range (the Jan 2012 and Feb 2012 in the sampel above) and add a column for each of the months.

How should I implement this using SSRS?

If you’re stuck with Tablix, here’s a similar situation that I have solved, How do i represent an unknown number of columns in SSRS?.
