有熟悉事务或PDO的吗？老是回滚，删除不掉数据解决方法

  $king->db->connect(); //连接数据库 $link为数据库连接句柄。 
 $king->db->link->beginTransaction();//回滚起始点 
 if($rs1=$king->db->getRows_number('%s_newsContent',"newsID in($newsID)")) 
 { 
  if($rs2=$king->db->query("delete from %s_newsContent where newsID in($newsID)")) 
  { 
   $s.="删除新闻内容成功！[".$rs2."/".$rs1."条]
"; 
  } 
  else 
  { 
   lzj_message('删除新闻内容失败','javascript:history.go(-1)');    
  } 
 } 
 if($rs1=$king->db->getRows_number('%s_rss',"idValue in($newsID) and tableName='news' and idName='newsID'")) 
 { 
   
  if($rs2=$king->db->query("delete from %s_rss where tableName='news' and idName='newsID' and idValue in($newsID)")) 
  { 
    
   $s.="删除新闻RSS成功！[".$rs2."/".$rs1."条]
"; 
  } 
  else 
  { 
   lzj_message('删除新闻RSS失败','javascript:history.go(-1)'); 
  } 
 } 
 if($rs=$king->db->query("delete from %s_news where newsID in(".$newsID.")")) 
 { 
  lzj_message("删除成功！[".$rs."条]
".$s,$pageUrl);   
 } 
 else 
 { 
  lzj_message('删除新闻失败','javascript:history.go(-1)'); 
 }  
 $king->db->link->commit();//回滚结束点
