这段discuz慢查询是用作什么的？一般在什么地方？

有办法修改这段吗

SELECT pre_forum_post.fid,pre_forum_post.message,pre_forum_post.subject,pre_forum_post.first,pre_forum_forum.fup FROM pre_forum_post,pre_forum_forum WHERE pre_forum_post.tid='6540' and pre_forum_post.fid=pre_forum_forum.fid and pre_forum_post.invisible='0' and pre_forum_post.status='0' ORDER BY pid

求大佬帮忙解答
