织梦使用sql调用disucuz2.5到首页的方法

{dede:sql sql="SELECT ultrax.pre_forum_threadimage.tid, ultrax.pre_forum_threadimage.attachment, ultrax.pre_forum_thread.tid, ultrax.pre_forum_thread.fid, ultrax.pre_forum_thread.subject
 FROM ultrax.pre_forum_threadimage
LEFT JOIN ultrax.pre_forum_thread ON ultrax.pre_forum_thread.tid = ultrax.pre_forum_threadimage.tid
 WHERE displayorder >=0
 LIMIT 0 , 2"}
   <li><A href="/bbs/forum.php?mod=viewthread&tid=[field:tid /]"><IMG src="bbs/data/attachment/forum/[field:attachment/]"  width="153px" height="100px"></A></li>
   <li><A href="/bbs/forum.php?mod=viewthread&tid=[field:tid /]">[field:subject function="cn_substr('@me',28)" /]</A></li>
   {/dede:sql}
