Hello, great perlmonks.How can I check if a mysql database is empty and print a message that it's empty. I have tried the following code: 
my $sth=$dbh->prepare("SELECT Email FROM foo ");
  $sth->execute();
  while (my $email=$sth->fetchrow_array ) {
                 if ($email=""){
                               print "Database is empty";
                                }
                                else {
                                     print $email;
                                     }
                                     }
$sth->finish;

In this way it's printing nothing when the database is empty, and when there is something in the database it's printing "database is empty" for every $email. Thank you very much for your time.
