Question

我有3张桌子：

SMS_IN 带有“原始”号码（数据通过短信发送，因此所有号码都是以短信格式发送的：我正在'爆炸'将它们分成一个数字）：
```
sms_text
sender_number
sent_dt
```
members ：
```
Memberid
Username
comp_id
phone
```

mobile_numbers_test 所有数字的表格：

Memberid
comp_id
numbers
contact_number
active

我试图将SMS_IN（新号码）转换为mobile_numbers_test（旧数字），并进行2次检查：

SMS_IN.sender_number = members.phone;和
如果SMS_IN.sender_number = mobile_numbers_test.contact_number AND SMS_IN.sms_text（以爆炸形式）= mobile_numbers_test.numbers，请跳过（或覆盖） - 否则INSERT。

这是我到目前为止所做的：

include ('database_connection.php');

$result = mysql_query("SELECT phone FROM members")
or die(mysql_error());  
$no=0;
echo'<table>
        <tr>
        <td>Numbers</th>
        <td>From</th>
        <td>Date</th>
        </tr>';
while($row = mysql_fetch_array($result))
    {$no++;
    $phone= $row['phone'];  
    $comp_id =  $row['comp_id'];
    $result1 = mysql_query("SELECT * FROM SMS_IN where sender_number ='$phone'")
    or die(mysql_error()); 
    while($row = mysql_fetch_array($result1))
        {$no++;
        $sms= $row['sms_text'];
        $sms_no=$row['sender_number'];
        $sms_time=$row['sent_dt'];
        $sms_exp = explode("\r\n",$sms);
        foreach($sms_exp as $no )
        { //** not working from here **//

        $result2 = mysql_query("SELECT * FROM members,mobile_numbers_test,SMS_IN 
        where members.phone = SMS_IN.sender_number and 
        mobile_numbers_test.numbers != '$no'
        ")
        or die(mysql_error());

        while($row = mysql_fetch_array($result2))
        {
        $circle=$row['state'];
        $price='Call Us';
        $contact_person=$row['Username'];
        $contact_number=$row['phone'];
        $type='Fancy';
        $per_post='Pre-Paid';
        $provider=$sms_exp[0];
        $date=strtotime($sms_time);
        $ip=$sms_no;
        $old_no=$row['numbers'];;

        if($old_no!=$no){ 
            echo '<tr><td>'.$no.'</td>';
            echo '<td>'.$contact_person.'</td></tr>';
        } else { echo 'Old No';
        }
        }
        }
        }

        }       
    echo'</table>';

在此示例中我echo答案，以便我知道会发生什么......我如何UPDATE或INSERT？

Answer 1

在UNIQUE上mobile_numbers_test创建一个(contact_number, numbers)索引（如果尚未存在）：
```
ALTER TABLE mobile_numbers_test ADD UNIQUE INDEX (contact_number, numbers);
```

加入members加上SMS_IN加入条件：

SELECT * FROM members JOIN SMS_IN ON SMS_IN.sender_number = members.phone

循环结果集，使用mobile_numbers_test扩展数字并插入INSERT IGNORE。把它们放在一起（使用PDO，因为它会让你的生活更轻松，你真的应该停止使用古老的mysql_*函数编写新的代码：它们不再被维护，社区已经开始了{{3} }）：

$dbh = new PDO("mysql:host=$hostname;dbname=$database", $user, $pass);

$select = $dbh->query("
  SELECT * FROM members JOIN SMS_IN ON SMS_IN.sender_number = members.phone
") or die($dbh->errorInfo());

$insert = $dbh->prepare("
  INSERT IGNORE INTO mobile_numbers_test
           ( Memberid,  comp_id,  numbers,  contact_number)
    VALUES (:Memberid, :comp_id, :numbers, :contact_number)
");

while($sms = $select->fetch()) {
  foreach(explode("\r\n",$sms['sms_text']) as $no) $insert->execute(array(
    'Memberid'       => $sms['Memberid'],
    'comp_id'        => $sms['comp_id'],
    'numbers'        => $no,
    'contact_number' => $sms['sender_number']
  ));
}

使用PHP更新/插入三个MySQL表
