Re^4: Add new data to array

The idea is strange, but the data in status => "Houses" needs to be in status => "Main" only and it isn't formatted like that in the database, so by using the magic of Perl, I was sure that it would be possible. This is what could work, unless it could be even more simplified.

#!/usr/bin/perl

use strict;
use warnings;

use DBI;

use Data::Dumper;

my $data =[
   { Ad1 => '20 SOUTH CENTRAL  #B3', status => 'Main',     City => 'NY
+', zCode => '0002', name => 'John D' },
   { Ad1 => '15 SOUTH CENTRAL  #B4', status => 'Property', City => 'NY
+', zCode => '0002', name => 'John V' },
   { Ad1 => '100 main St.',          status => 'Houses',   City => 'BO
+', zCode => '0007', name => 'Mary Due'   },
   { Ad1 => '5540 Chelsea Avenue',   status => 'Cabin',    City => 'NE
+', zCode => '4562', name => 'Carly Simon' },
  ];

 my %last_houses;

 foreach my $hr_row (@$data) {

   if ($hr_row->{ 'status' } eq 'Houses') {
     @last_houses  { qw(new_name  new_aA1  new_City  new_zCode) } =
       @{ $hr_row }{ qw(name      Ad1      City      zCode     ) };
     }

  }

 foreach my $hr_row (@$data) {

   if ($hr_row->{ 'status' } eq 'Main') {
     %$hr_row = (%$hr_row, %last_houses);
   }

 }

 print Dumper $data;
=code
$VAR1 = [
          {
            'new_City' => 'BO',
            'status' => 'Main',
            'name' => 'John D',
            'City' => 'NY',
            'new_aA1' => '100 main St.',
            'new_zCode' => '0007',
            'Ad1' => '20 SOUTH CENTRAL  #B3',
            'zCode' => '0002',
            'new_name' => 'Mary Due'
          },
          {
            'status' => 'Property',
            'name' => 'John V',
            'Ad1' => '15 SOUTH CENTRAL  #B4',
            'City' => 'NY',
            'zCode' => '0002'
          },
          {
            'status' => 'Houses',
            'name' => 'Mary Due',
            'Ad1' => '100 main St.',
            'City' => 'BO',
            'zCode' => '0007'
          },
          {
            'status' => 'Cabin',
            'name' => 'Carly Simon',
            'Ad1' => '5540 Chelsea Avenue',
            'City' => 'NE',
            'zCode' => '4562'

I'm glad that you have a working solution. Personally, I would hesitate to try to simplify it since I don't understand the rationale of what it's supposed to do. :) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

When comes to data, sometimes there is no choice other than format it the way it will work for you, in this case, I needed to go through this nightmare to have it the way I needed. Now I only need to select this block with all the data I need, its just hard to explain sometimes. `{ 'new_City' => 'BO', 'status' => 'Main', 'name' => 'John D', 'City' => 'NY', 'new_aA1' => '100 main St.', 'new_zCode' => '0007', 'Ad1' => '20 SOUTH CENTRAL #B3', 'zCode' => '0002', 'new_name' => 'Mary Due' },` [download]	[reply] [d/l]
