LOOP调用代码：
{dede:loop table=’wp_posts’ sort=’post_date’ row=’20′ if=”}<br> 
<a href=”[field:guid/]“> [field:post_title/]</a> <br /> 
{/dede:loop} 

SQL掉用方法：
{dede:sql sql=’Select * from wp_posts order by post_date desc limit 0,20′} 
<li><a href=’[field:guid/]‘ target=’_blank’>[field:post_title/]</a></li> 
{/dede:sql}
