I can write no problem, but cannot for the life of me figure out how to perform a select for read purposes and print the variable out.

Here is my task: Read an email address from database and send email to address

    my $sth = $dbh->prepare(<<SQL);
    Select Email1 from client where reg = ?
SQL
    $sth->execute($id) or err_trap;
    
    while ($sth->fetchrow) {
        print "string $_";
    }

The problem is after $sth-> execute line. I cannot figure how to read the value to the select into a scalar. I can do this without using placeholders, but do not want to. I like to security of using placeholders.

THanks
