I'm a little stumped on how best to approach a particular problem.� I have a report I'm building that will span an uncertain number of columns and uncertain number of rows.� Below is a sample of what the report might look like:

The data I pull from the database comes into a result set that looks like this:

Account�� Month���� Amount
51112������� 1��������� 5
51112������� 2�������� 10
51112������� 7�������� 15
51119������� 6��������� 7
51121������� 2�������� 20
51121������ 11����� ����3
..

Look at the following thread http://www.perlmonks.org/index.pl?node_id=324008


I have a complete, working code snippet there for normalizing a denormalized recordset. You can use that as the base to build your own data transformation routine.
