多表关联调用
表 business_circle
字段 id  name  parent_id 

表 goods_area
字段 goods_id  city  area 


$sql = mysql_query("select * from goods_area as a INNER JOIN business_circle as b on a.area=b.name order by a.goods_id asc");
while($rs = mysql_fetch_assoc($sql)){
   echo $rs['area'].$rs['parent_id'].'
';
}




这样能调用处parent_id的值但我想调用出条件parent_id = id表business_circle里的name值

不知道讲的清楚吗?高手直接给完整代码,谢谢了
