Printing Data to Email body from Perl

[Anonymous Monk]

Hi,
Below script reads a log file (which contains a list of id's) and selects the same Data from the log file with the Oracle tables. Can someone help how to extent the script in a way that : when selecting /reading if it finds unmatched id's it has to send an email with the Body of the email as:

log: 17
Database: 16
list of not found id :
id1
id2

#!user/local/bin/perl
use strict;
use warnings;
use DBI;


my $dir = '/usr/home/Scripts/Test';


# get the text files from the specified dir
opendir DIR, $dir or die "could not open directory $dir: $!";
my @files = grep /\.txt$/, readdir DIR;
closedir DIR;


my $dbh = DBI->connect("dbi:Oracle:****", "****", "*****" )
    || die( $DBI::errstr . "\n" );
$db->{AutoCommit}    = 0;
$db->{RaiseError}    = 1;
$db->{ora_check_sql} = 0;
$db->{RowCacheSize}  = 16;

foreach my $fil (@files) {

# read the ids from the files

    open IN, "$dir/$fil" or die "could not read $fil: $!";

   #my @ids = map { chomp; "'$_'" } <IN>;

    my @ids = map { "'$_'" } map { chomp; split /\s+/ } <IN>;

 
print "checking ", scalar(@ids), " ids from $fil\n";
print"@ids\n\n";
    

my $sel=$db->prepare("select (number||'/'||id) as List_ID from Info wh
+ere List_ID in (" . join(', ', @ids) . ')');
   $sel->execute();
while(my $subref = $SEL->fetchrow_hashref()) {
    my $list=$subref->{'LIST_ID'};
print "$list\n";

}

This snippet might be helpful, and there are modules for checking lists.

#!/usr/bin/perl

my @a = qw(a b c d e f);
my @b = qw(c d e f g h);
my ($only_a, $only_b, $both, $either) = listy(\@a, \@b);
print "only in a: @$only_a\n";
print "only in b: @$only_b\n";
print "both: @$both\n";
print "either: @$either\n";

sub listy {
  my %tmp1;
     for (0..1) {
        for my $k (@{$_[$_]}) {
        $tmp1{$k} .= $_;
      }
  }

my %tmp2;

while (my($k, $v) = each %tmp1) {
    push @{$tmp2{$v}}, $k;
   }

return @tmp2{"0", "1", "01"}, [keys %tmp1];
}

Hi,

Thank you for the code snippet but I am looking for something which can go with the exsisting script rather than new one. so is it possible to extend the current script

I'm sure you have already looked at the Email modules that CPAN provides. Please tell us why the modules are unsatisfactory and didn't do what you needed. Particularly, MIME::Lite works very well in sending emails.

If you have other questions than how to send mail from a Perl script, maybe you should make that clearer in your post.

Also note that we expect you to do your own work. This is not a script writing service, so "something which can go with the existing script" will have to be something you write from the solutions you find.

After you check your lists, here is a basic mailing subroutine. Change the Content Type to plain text if you don't want to add attachments.

#!/usr/bin/perl

#This is the sending routine from a larger program which uses both Mim
+e::Lite
# and Net::SMTP, which does the mail server login.
# Variable names passed to the routine should be self explanatory.

sub sendmsg {
my ( $From_Addr, $Mail_Name,  $Subj_Text, $Body_Text, $File_Name,
$Mime_Data,) = @_;

my $msg = MIME::Lite->new(
 From =>$From_Addr,
 To =>$Mail_Name,
 Subject =>$Subj_Text,
 Type =>'multipart/mixed',
);

$msg->attach(Type=>'TEXT',
  Data=>$Body_Text,
);


$msg->attach(Type=>'application/octet-stream',
  Data=>$Mime_Data,
  Filename=>$File_Name,
);

MIME::Lite->send('smtp', "mail.somewhere.net", Timeout=>60);
}
