in reply to Perl and DBI and CGI

I agree with blazar on both points, but try this & see if it sheds some light: 
use Data::Dumper;
my $ref = $dbh->selectall_arrayref("select * from users") 
            || die $dbh->errstr;

print Dumper($ref);

    Dear monkey_boy ! Thank you, Much better, but I have no idea how to improve formating and assign fields to the variables: $Name and $Email. In other words, how to make 
    print "<font color=\"red\"> $Name";
print "<font color=\"ble\"> $Email";

      Hi! Check if this is helps... 
      
$query = "SELECT Name, Email FROM users";
$sth = $dbh->prepare($query);
$sth->execute();
while($Name,$Email) = $sth->fetchrow_array){
print "$Name, $Email";}
$sth->finish();

        Hi,

        The code is right, but using arrayref is more efficient/faster, consider it if you have a lot of data.

        Regards,
        ;-)

        Sorry, it does not help.

      You would be better specifying the column names in the sql, thus would be able to help you more, also dont forget to close your font tags , something like this: 
      


my $ref = $dbh->selectall_arrayref("
          select name  , 
                 email , 
                 age 
            from users
") || die $dbh->errstr;

foreach my $person (@{$ref}) {
        my ($name,$email,$age) = @{$person};

        print "<font color=\"red\" > $name  </font>";
        print "<font color=\"blue\"> $email </font>";
        
};

      Hint: use alternate delimiters, e.g. qq|"$whatever"|.
