If you use a hashref as the slice arg to fetchall_arrayref you will receive an AoH rather than an AoA. Then it becomes trivial:

my $query = $connect->prepare ("SELECT * FROM TableName");
$query->execute ();
my $data = $query->fetchall_arrayref ({});
for my $row (@$data) {
    for my $key (keys %$row) {
        print "Column name is $key, column value is $row->{$key}\n";
    }
}
