代码应该没问题吧，join和count单独用一次都成功，但是用两次就会出现数据统计错误：

$list=$data->join(array('renyuan ON renyuan.ry_pid=id','jiti ON jiti.jt_pid=id'))->where($map)->field(array("count(ry_id)"=>"country","count(jt_id)"=>"countjt","mingcheng","date","create_time","id"))->limit($Page->firstRow.','.$Page->listRows)->order("date")->group('id')->select();

请大家帮助，谢谢
