运用临时表查询数据（实际开发中遇到的解决）

$sql3="CREATE TEMPORARY TABLE atmp_table(uid int(11),dnum int(20) not null)";
		mysql_query($sql3);
		$sql3="INSERT into atmp_table(uid,dnum) SELECT uid,count(soid) as dnum
	FROM `cy_score2`
	where (nei='下载' or nei='下载试题')  
	group by uid having dnum>150
	order by dnum desc limit 10";
		mysql_query($sql3);
		$sql3="select a.uid,count(b.tid) as unum from atmp_table a left join cy_test b on a.uid=b.uid
	group by b.uid
	order by a.dnum desc,unum asc limit 5";
		$query4=mysql_query($sql3);
                  $rs=mysql_fetch_array($query4)
