Subject: [Chicago-talk] Holiday Meetings - Monk's Pub; Venue needed
Message-ID: <937D2510-68C9-4958-9690-16CA161D58AF@gmail.com>

As we go into the holiday season, we are in need of a new venue to hold our meetings. If anyone has some meeting space, let me know.

In lieu of an office hours, there will be an informal social get-together at Monk's Pub (http://www.monkspubchicago.com <http://www.monkspubchicago.com/>), Thursday November 5 (tomorrow) at 7:00pm. brian d foy, author of several Perl books, numerous CPAN modules, and founder of the Perl Mongers groups, is in town.

So come down, have a few drinks, and talk about Perl!

He moved to New York a few years back. He's only in town for a couple days
here and there at this point.

Subject: [Chicago-talk] Combine like hash elements
Message-ID: <20151123101041.5shga4s5s8ggcwgw@hostingemail.xo.com>

I have a hash reference with the following structure:

{
'11' => {'AMOUNT' => '20.00','ID' => '11','NAME' => 'Lincoln Park'},
'12' => {'AMOUNT' => '38.00','ID' => '12','NAME' => 'Bucktown'},
'13' => {'AMOUNT' => '41.00','ID' => '12','NAME' => 'Lincoln Park'}
}

Can anyone tell me how I can combine them by 'NAME' so that I would have:

{
'11' => {'AMOUNT' => '61.00','ID' => '11','NAME' => 'Lincoln Park'},
'12' => {'AMOUNT' => '38.00','ID' => '12','NAME' => 'Bucktown'},
}

Thanks

Did not include it because it did not come close but if you must see it 
here it is:
?
?%$w_ref = sort { %$w_ref{$a}  %$w_ref{$b} } keys %$w_ref;

What that?s doing is sorting.  There?s no combining going on.  You?re going to need to write something that goes through your hash values and finds the ones that have the same name and add the AMOUNTs together.

Richard,

So, you want the new hash to have fewer elements.  There may be an
idiomatic way, but the straightforward way would be to cycle through
your old hash building a new hash of totals. Let's say your hash is
%trans, then:

my %total_trans;
for my $k ( keys %trans) {
  my $name = $$trans{$k}->{'NAME'}; # check if this is right
  my $amount = $$trans{$k}->{'AMOUNT'}; # check if this is right
  $total_trans{$name} += $amount;
}
printf "%.2f\n", $total_trans{'Lincoln Park'}; # prints 38.00

You'll have to check the two temporary variables to ensure I
dereferenced them correctly and then you could factor them out.  You
could modify this so the new hash has the same structure as the old hash.

I think this would be clearer than trying to edit the original hash.
Pity your data are not in a database where this would be a simple
database call.

-Alan

I am guessing there is a typo in the sample input data. In the third entry,
isn't the key and ID value supposed to be the same? Is it supposed to be 11
or 13? If it is the way it is or if it really is 13, then you need to
arbitrate which key and/or ID the resulting hash will have.

{
'11' => {'AMOUNT' => '20.00','ID' => '11','NAME' => 'Lincoln Park'},
'12' => {'AMOUNT' => '38.00','ID' => '12','NAME' => 'Bucktown'},
'13' => {'AMOUNT' => '41.00','ID' => '12','NAME' => 'Lincoln Park'}
}

A quick attempt (without preserving the ids which are ambiguous as imran
said):

my %totals;
$totals{$_->{NAME}} += $_->{AMOUNT} for values %$orig;

You don't seem to care about the keys (loosing key "13" wasn't
a problem). 

Q: Are the ID values important or could they be discarded?

If so then just make a new hash keyed by NAME and accumulate
the AMOUNT values:

    my %resultz = ();

    for( values %inputz )
    {
        my ( $name, $amt, $id )  = @{ $_ }{ qw( NAME AMOUNT ID ) };
        my $val
        = $resultz{ $name } ||= { ID => $id, NAME => $name };

        $val->{ AMOUNT }    += $amt;
    }

    # at this point %resultz is keyed by name with an id and amount
    # for each entry.

    %inputz = ();

    while( my ( $name, $val ) = each %resultz )
    {
        $inputz{ $val->{ ID } } = $val;
    }

    # at this point the original inputs hash is keyed by ID
    # with values having a name, accumulated amount, and id.
    # multiple id's are collapsed into a single ID with the 
    # value of the first record for that name.

Hello Everybody,
?
Thank you for all the replies. The ID field did not need to be 
preserved. However, I was having difficulty conceptualizing the 
manipulation of the hash so I decided to use DBI->bind_colums instead 
and iterate throught the values in a way that I found at least a bit 
more clear. Still working on cleaning this up but this is at least the 
direction that I am going in. 
?
Thanks again for the help. 
?
?? my ($DID, $AMOUNT, $NAME,);
??? $sth->bind_columns(\($DID, $AMOUNT, $NAME));

my $lastN;
my $lastA;
my @CAMS;
my $keepN;
my $keepA;

while ($sth->fetch) {
?
if ($lastN) {
???
??? if ($NAME eq $lastN) {

??? #print "Combine $AMOUNT, $NAME\n";
??? $keepA = $AMOUNT + $lastA;
??? $keepN = $NAME;
???
??? } else {

??? $keepA = $AMOUNT;
??? $keepN = $NAME;

??? }

}

# print "$DID, $AMOUNT, $NAME\n";

$lastN = $NAME;
$lastA = $AMOUNT;

push(@CAMS, $keepA . " " . $keepN);

}

You could also push the aggregation to the DB server and have it do the sum
by name.

I disagree that this should be put in a database unless you have sufficient
values to warrant that. If you are dealing with just a few dozen values
relying upon a database to essentially sort a hash is not very Perl-ish I
think. At any rate, here is a more verbose example that uses Data::Dumper.
The other examples provided before should be better, but I offer this
because you can debug it and see what is happening line by line:

use strict;
use Data::Dumper;
my $targetRef;
my $hashRef =
{
    '11' => {'AMOUNT' => '20.00','ID' => '11','NAME' => 'Lincoln Park'},
    '12' => {'AMOUNT' => '38.00','ID' => '12','NAME' => 'Bucktown'},
    '13' => {'AMOUNT' => '41.00','ID' => '11','NAME' => 'Lincoln Park'}
}; #ID on line 3 fixed to match first line id

foreach my $structId(keys %$hashRef)
{
    my $struct = $hashRef->{$structId};
    if (!$targetRef->{$struct->{'ID'}}){
    $targetRef->{$struct->{'ID'}} = {   'NAME'  => $struct->{'NAME'},
                                            'ID'    => $struct->{'ID'},
                                            'AMOUNT'=> $struct->{'AMOUNT'}
};
    } else {
    $targetRef->{$struct->{'ID'}}->{'AMOUNT'} +=
        $struct->{'AMOUNT'};
    }
}

print Dumper $targetRef;

1;

== produces ==

$VAR1 = {
          '12' => {
                    'ID' => '12',
                    'AMOUNT' => '38.00',
                    'NAME' => 'Bucktown'
                  },
          '11' => {
                    'NAME' => 'Lincoln Park',
                    'AMOUNT' => '61',
                    'ID' => '11'
                  }
        };
