php\u网络\u获取地址错误

我正在尝试从数据库中获取数据，查询在sql引擎上运行良好。但当我试图从实际需要的php文件中触发它时，我得到了php_network_getaddress错误

表单成功提交了数据，变量成功存储了值，查询没有错误，错误仍在发生。我无法理解。任何帮助都将不胜感激

这是我的php文件：

这是你的问题：

$query=mysql\u connect选择日期日期时间作为日期，将账单金额作为金额，将会员金额作为tbl\u交易的客户，其中日期日期时间='2014-03-17'或日期日期时间='2014-03-18'按日期时间分组

您应该使用mysql\u查询而不是mysql\u连接您的连接已处于活动状态

另外，我知道名称并不重要，但您应该注意，$query变量保存的是查询结果，而不是查询本身

注意：mysql_*函数已弃用！考虑使用MySqLI/PDO。< /P>

<?php

$con = mysql_connect('localhost', 'root', '') or die('Error connecting to server');

mysql_select_db('db_MarkitBerry', $con); 

$cust_flow_1=0;
$cust_flow_2=0; 
$coll_flow_1=0;
$coll_flow_2=0;
    if(isset($_GET['submit']))
    {
        $date1=$_GET['datepicker'];
        $date2=$_GET['datepicker1'];

        $query=mysql_connect("SELECT DATE( date_time ) AS DATE, SUM( bill ) as amount , SUM( members ) as customers FROM  tbl_transaction WHERE DATE( date_time ) =  '2014-03-17' OR DATE( date_time ) =  '2014-03-18' GROUP BY DATE( date_time )");
        while($row=mysql_fetch_array($query))
        {
                $cust_flow_2=$row['customers'];
                $coll_flow_2=$row['amount'];
                echo $cust_flow_2;
                echo $coll_flow_2;          
        }
    }
