Error in mysql queries for Drupal that has table prefix

in file advanced_forum.module, the sql queries use table with no prefix. Like this (line 488):

$query = "SELECT n.title AS nodetitle, res.title AS restitle, res.created, res.type AS restype, n.type AS nodetype, n.nid AS nid, t.tid, res.cid AS cid FROM node AS n INNER JOIN (SELECT title, created, nid, uid, type, 'cid' AS cid FROM node UNION SELECT subject, timestamp, nid, uid, 'comment', cid FROM comments ORDER BY created DESC) AS res ON n.nid=res.nid INNER JOIN term_node AS t ON n.nid = t.nid GROUP BY tid;";

tables used: node, comments.

Table with prefix will receive warning like:

user warning: Table 'dbname.node' doesn't exist query: SELECT n.title AS nodetitle, res.title AS restitle, res.created, res.type AS restype, n.type AS nodetype, n.nid AS nid, t.tid, res.cid AS cid FROM node AS n INNER JOIN (SELECT title, created, nid, uid, type, 'cid' AS cid FROM node UNION SELECT subject, timestamp, nid, uid, 'comment', cid FROM comments ORDER BY created DESC) AS res ON n.nid=res.nid INNER JOIN term_node AS t ON n.nid = t.nid GROUP BY tid; in /home/username/public_html/sites/all/modules/advanced_forum/advanced_forum.module on line 490.
