KS_msj这个只可以用一次把，你连续用这个数据表，会报错把，呵呵，我记得我报过错

而且用联合语句会出错
select top 1 title,id,photourl,intro,adddate,1 as a from ks_article where picnews=1 and recommend=1 and tid='{$Param(0)}' order by adddate desc
union all
select top 4 title,id,intro,photourl,adddate,2 as a from ks_article where recommend=1 and tid='{$Param(0)}' and id not in(select top 1 id from ks_article where picnews=1 and recommend=1 and tid='{$Param(0)}' order by adddate desc) order by a, adddate desc
这是我网站上的一个联合的，结果不采集最新新闻，永远是之前那几条。红色加粗来链接
