mysql字段类型为int默认null,插入却显示0的解决办法,参考php代码

";
//exit;
exequery(TD::conn(),$query);

$id=mysql_insert_id();

    $from_id=$_SESSION["LOGIN_USER_ID"];
	$content_sms="新建业务进度日志提醒：";
if($field1!=""){
	 $content_sms.="合同号：".$field1."；"; }
if($field3!=""){
	 $content_sms.="船名：".$field3."；"; }		 
	// $REMIND_URL1="yewurizhi/manage/modify1.php?id=".$id;
	 $REMIND_URL2="yewurizhi/manage/modify2.php?id=".$id;
	 $REMIND_URL3="yewurizhi/manage/modify3.php?id=".$id;
	 $SEND_TIME=date("Y-m-d H:i:s");
	 send_sms($SEND_TIME,$from_id,$TO_ID_SMS_MAOJIN,0,$content_sms,$REMIND_URL2);//0是系统提醒
	 send_sms($SEND_TIME,$from_id,$TO_ID_SMS_CAIWU,0,$content_sms,$REMIND_URL3);

   	Message("提示：",_("业务进度日志新建成功！"));
