PHP 2010 Version: 6.0.813一个错误

function king_ajax_delete_upfile(){

 global $king;
 $king->access('#upfile_delete');
 $_list=kc_getlist();

 if(!$res=$king->db->getRows('select kpath from %s_upfile where kid in ('.$_list.');'))
  $res=array();
 foreach($res as $rs){
   $rs['kpath']='../'.$rs['kpath'];
   kc_f_delete($rs['kpath']);//删除文件
 
 }
 $king->db->query('delete from %s_upfile where kid in ('.$_list.');');
 kc_ajax('OK',"<p class="k_ok">".$king->lang->get('system/ok/delete')."</p>",1);

}
红色部分原 sql语句两头原处为双引号，查询为空。。导致无法删附件。。
