in thread Perl and DBI and CGI

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";

    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>";
        
};

        Im finding it hard to help as you dont provide data for us!
        What does this print? 

        use Data::Dumper;
my $ref = $dbh->selectall_arrayref("select * from users") 
            || die $dbh->errstr;

print Dumper($ref);

    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();
$dbh->disconnect;

      Hi,

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

      Sorry, it does not help.

        I am really sorry that it is not working for you. Actually, I created a temptable and tried executing the code that you are using; 
        my $ref = $dbh->selectall_arrayref("
           select name, email from testtable") || die $dbh->errstr;

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

        print "<font color=\"red\" >Name :  $name  </font>";
        print "<font color=\"blue\"> Email : $email </font><br>";     
+   
}

        It runs just fine even with the "Dr. John Bull". Please check the database if some special characters are not slipped thru.
        here is the output
        Name : Dr. John Bull Email :

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