Thanks for that insight. Refering back to my post above, "will fetchall_arrayref affect clobs?".... I have tried the following code: 
sub get_all_data{
    my $max_rows = 5000;

    while (my $aref = $sth2->fetchall_arrayref(undef, $max_rows))
    {
        $struct = $dbh_ideas->ora_lob_read(@$aref[1],1,65536);
        push @$raResults, [ $aref[0],$struct ];
    };

return $raResults;
}

Then later: 

  $p = Project->new_project($id);
  $cursor = $p->get_all_data;

foreach my $row (@$cursor){
    print OUTPUT do{
        local $" = qq{\t};
        qq{$row->[1]\$\$\$\$\n};
        } if defined $row->[1];
}

My output file doesnt get written, but equally doesnt die either. I get a "locator is not of type OCILobLocatorPtr at Project.pm line 146." error message. It is something to do with ora_lob_read - does anyone know the syntax for this situation? Thanks
