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:


Account   Descr   Jan   Feb   Jun   Aug   Nov     Total 51112     Fred     $5   $10    $0   $15    $0       $30 51119     Lucy     $0    $0    $7    $0    $0        $7 51121     Ethel    $0   $20    $0    $0    $3       $23 51178     Ricky    $1    $6    $3    $2    $4       $16

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.
