OK I'll explain here with code what I am trying to accomplish, please let me know if you understand, I have comments on the code explaining as well, I would really appreciate any feed back on this!

# Start first sql...

my $dbh = DBI->connect...

my $sql = "

                  acc_num,

my $header = [
                  "Acc. Num",

# Here is another question and problem I am having, as you can see I n
+eed to rearrange the columns to mach the order on $header, and 
# $email, $country are coming from the first query and $user3 and $use
+r7 fro mthe second, I need to reorganize the data to have some consis
+tency 
# when processing the rest of the code to be printed on this report. H
+ow can this be done?

# Here I need to add @{ $new_array_ref } to  @{ $new_array_ref_b } to 
+contain all the data I need to print a report and
# make sure that if data from the first table query has more data than
+ the results from the second table dont generate any error, if it is 
+it will
# insert a '' to the value and it will print nice on the report

for my $i (0..$#$new_array_ref) {

    push @{$new_array_ref->[$i]}, @{ ref($new_array_ref_b->[$i]) eq 'A
+RRAY' ?
                             $new_array_ref_b->[$i] : [(' ') x 3]   };
    
}



# This will add some data for the table header when printing this repo
+rt that will be done in pdf later
unshift @{ $new_array_ref }, $header;

##Now if all its done OK go here:

main_table($pdf, \@{$new_array_ref});
$pdf->saveas();


sub main_table {

    my $pdf  = shift;
    my $data = shift;
  
do more stuff......
