[wp-testers] Can someone verify this code change for me..

[spencerp]

This here:
$sql_join_post2cat = "LEFT JOIN $tablepost2cat ON 
$tablepost2cat.post_ID=$tablecomments.comment_post_ID ";

Should be made like this right?
$sql_join_post2cat = "LEFT JOIN $wpdb->post2cat
 ON $wpdb->post2cat.post_ID=$wpdb->comments.comment_post_ID ";

I'm asking, because I'm not a PHP professional yet.. but, working on it LOL! 
=)
