The following error seems to be generated each time the cron job runs:

user error: You have an error in your SQL syntax near 'ON b.nid = n.nid WHERE n.status = 1 AND n.moderate = 0 AND (created > 1110834148' at line 1 query: SELECT b.nid as lno, b.booktitle as text1, b.review as text2, b.synopsis as text3, b.contents as text4, b.publisher as text5 FROM bookreview b JOIN node n ON b.nid = n.nid WHERE n.status = 1 AND n.moderate = 0 AND (created > 1110834148 OR changed > 1110834148) in /home/therune/www/includes/database.mysql.inc on line 125.
