PHP 显示问题

    
               include($_SERVER['DOCUMENT_ROOT']."/auth.php");//调用数据库连接文件
        $query3 = "select count(*) from (select * from (select * from bydms_dutyapp where dutyapp_approverid='$MY_SYSNUMBER' order by dutyapp_datetime desc ) as  bydms_tempa left join bydms_project on dutyapp_projectid=project_id ) as  bydms_tempb where dutyapp_result='审批中' "; 
        $result3 = mysql_query($query3);
        while ($row = mysql_fetch_array($result3)) {     //

输出所有的查询结果
echo "您当前有".$row."条待审批流程！";
}
?>

这段代码有错吗？

echo "您当前有".$row[0]."条待审批流程！";

------解决方案--------------------
$result3 = mysql_query($query3) or die(mysql_error());
------解决方案--------------------

$query3 = "select count(*) from (select * from (select * from bydms_dutyapp where dutyapp_approverid='$MY_SYSNUMBER' order by dutyapp_datetime desc ) as  bydms_tempa left join bydms_project on dutyapp_projectid=project_id ) as  bydms_tempb where dutyapp_result='审批中' "; 

把$query3打印出来放到数据库去执行看看有没有结果
