Hi there Monks!
I am querying a large table 50 records at a time, that works no problem, but at line 34 this code: 
$allaccounts = $sql_dbh->exec( "select * from othertable where acc in 
+($placeholders)", @files );

Is where I am having the issue I can't figure it out.
It seems that the account numbers in this variable "@files" has no comma separated between its values, this might be the cause, I am just confused on how to get it fixed. The reason might be because on line 30, if I use “push” adding those values into “@files, it will find them in the "othertable" table as you can see in this sample code I am posting here. Does the values in @files on line 34 needed to somehow have comma separated in order to the code to work? Any help its appreciated!
Here is the sample code for this: 
#!/usr/bin/perl -w

use strict;
use CGI qw/:standard/;
use POSIX qw(strftime);

my $db = "test";
my $sql_dbh = lib::Db->connect( 'local' );

# get a list of account numbers
my @data = map { $_->{ ACCOUNT } } @{ $sql_dbh->exec( qq|select accoun
+t from my_table where type='A'|) };

if (!@data) {
  die "bye now";exit;
 }

my $numb = @data;
print "\n Numbers of Accounts: $numb\n";

# Check 50 records at time 
my $allaccounts;
for( my $i = 0; $i < @data; $i += 50 ) {

  my @files = @data[$i .. $i+49];

  #my $all = join(', ', @files);
  #print "\n $i - $all\n";

  #test data
  #push(@files, "11223","5776","0001","87100");    

  my $placeholders = join ',', ('?') x @files;

  $allaccounts = $sql_dbh->exec( "select * from othertable where acc i
+n ($placeholders)", @files );
 
  
      
}

my $cc=0;
foreach (@$allaccounts) {
  $cc++;
  # print report
  my $found = qq|$_->{ name }$_->{ number }|;
  print "\n $cc - Reporting: $found\n"; 


 }
