I do not recommend using regular expressions to parse a CSV. What happens if part of the input includes a comma? In the Massive Overkill department, I would suggest using DBD::CSV:

   use DBI;
   $dbh = DBI->connect("DBI:CSV:")
       or die "Cannot connect: " . $DBI::errstr;
   $dbh->{'csv_tables'}->{'data'} = { 'file' => 'data.csv'};

   # Find the matching rows in the table
   $sth = $dbh->prepare('SELECT * FROM data ' .
                        'WHERE column1 = ? AND column2 = ? ' .
                        'AND column7 = ? AND column5 = ?', 
                        $one, $two, $three, $four)
        or die "Cannot prepare: " . $dbh->errstr();
   $sth->execute() or die "Cannot execute: " . $sth->errstr();

   my($id, $name);
   $sth->bind_columns(undef, \$id, \$name);
   while ($sth->fetch) 
   {
      # Print the name and id of each matching row
      printf("Found result row: id = %s, name = %s\n",
             defined($id) ? $id : "NULL",
             defined($name) ? $name : "NULL");
   }
   $sth->finish();
   $dbh->disconnect();
