Background:

I need to generate a report with pivoted data. My current process selects data from an Oracle query via the DBI module and loads that data into excel. I normally use the Spreadsheet::WriteExcel module however, it does not have pivot capabilities. So, John M. suggested that I use Win32-OLE.

i.e.

my $connection = DBI->connect('dbi:Oracle:xxxxx','xxxxx','xxxxx',{
    AutoCommit => 0,
    RaiseError => 1,
    PrintError => 1,
    }) 
|| die "Database connection not made: $DBI::errstr";
[download]

#select statement

my $stmt1 = "select *
from final_data_set_blu_ray
order by weekend_date";
[download]

#prepare statement

$query1 = $connection->prepare($stmt1);
[download]

#execute

$query1->execute() or die $connection->errstr;
[download]

#load data into an array reference.

my $a_row = $query1->fetchall_arrayref();
[download]

Once I have the data in an array reference, I can assign the data to an array or whatever to load it to excel. At this point, I can’t find any Win32::OLE logic / syntax that provides a clear example of taking queried data with an unknown range and creating a pivot table in excel. All of the examples I find have a pre-determined range for the spreadsheet like the example below:

i.e.

# Write all the data at once...

$rng = $xlBook->ActiveSheet->Range("A1:C7");
$rng->{Value} = $mydata;
[download]

# Create a PivotTable for the data...

$tbl = $xlBook->ActiveSheet->PivotTableWizard(1, $rng, "", "MyPivotTab
+le");
[download]

Using the above logic, is there a way to take the data from my query / DBI and assign it to a value like so “$rng->{Value} = $mydata;” to create a pivot table? With my queried data, my range will change each time. Can you give any tips to get around this?

I have worked on this for several days and I cannot find a solution. I wished that Spreadsheet::Write Excel had a pivot solution. Any help or direction will be greatly appreciated.
