        }
        // If the primary key is BIGINT we get an incorrect result
        // (sometimes negative, sometimes positive)
        // and in the present function we don't know if the PK is BIGINT
        // so better play safe and use LAST_INSERT_ID()
        //
        // When no controluser is defined, using mysqli_insert_id($link)
        // does not always return the last insert id due to a mixup with
        // the tracking mechanism, but this works:
        return $this->fetchValue('SELECT LAST_INSERT_ID();', 0, 0, $link);
