Hello,

I have this code, but it doesn't work for some reason.

I basically want to loop through the data structure in $results, and remove duplicates by putting the results in a hash, then loop through that hash before entering to the database

foreach my $host_results (@$results)
{
  foreach my $result_tab (@$host_results)
  {
    my $uniquekey = $result_tab->{'HostName'}.$result_tab->{'Qid'};

    if ($relayqid_hash{$uniquekey}) {
      # if the relayqid exists ignore
      my $existing_Recipient = $relayqid_hash{$uniquekey}->{'Recipient
+'};
    } else {
      # create the hash record with the result_tab in it
      $relayqid_hash{$uniquekey}= $result_tab;
  }
}

foreach my $host_key (keys %relayqid_hash)
{
  foreach my $result_tab (@$host_key)
  {
    my $subject = ($result_tab->{'Subject'}) ? $result_tab->{'Subject'
+} : "[no subject]";

  # do other stuff not important
  insert_hash($result_tab);

  }
}

What am I doing wrong here? Any help would be great, I think i'm just looping through and referencing things wrong in the second loop.

Thanks,

Tom
