連接2個不同的數據庫，不能正常工作

enter image description here連接2個不同的數據庫，不能正常工作

首先，我已經知道的mysql_connect如何不建議使用，但我沒有時間來學習PDO命令，一旦我解決了這個第一，我會將其更改爲PDO。但是現在，我仍然無法在每個文件上合併具有不同數據庫連接的兩個代碼。

<?php 



    $dbh1 = mysql_connect('localhost', 'root', ''); 
    $dbh2 = mysql_connect('localhost', 'root', '', true); 

    mysql_select_db('invoices', $dbh1); 
    mysql_select_db('hmis', $dbh2); 

    $id = '17'; 

    ///// 

     if ($id) { 
    echo "<h1>Edit Medical Records # : $id</h1>"; 
    } 
    else 
    { 
    echo " <h1>Medical Records</h1>"; 
    } 


    if($submit) 
    { 
    //-------------------check user name----------------------------------------------------- 
    $name = $_POST['name']; 

    $select = "select first_name from patient where last_name = '".$last_name."';"; 
    $query = mysql_query($select,$dbh1) or die ("Mysql error! It was: ".mysql_error()); 
    $rows = mysql_num_rows($query); 
    if ($rows != 0) 
    { 

     echo ("<script language=javascript>alert ('Sorry! $first_name is already taken!')</script>"); 
     echo ("<script language=javascript>document.location.href = 'editclient.php'</script>"); 

    exit; 
    } 
    if($name == "admin"){ 
     echo ("<script language=javascript>alert ('Sorry! $first_name is not a good thing to do!')</script>"); 
     echo ("<script language=javascript>document.location.href = 'editclient.php'</script>"); 
    exit; 

    } 
    //-----------------------------------end check------------------------------------------- 
    $sql = "INSERT INTO patient (`first_name`, `last_name`,`country`, `address`, `gender`, `telno`, `occ`, `spo`, `occ2`,`cp`, `tel2`, `reff`, `all`, `ill`, `mat`, `frat`, `datetime`, `vs`,`ppe`, `ffup`)

以上代碼的結果在上面的截圖中。我註釋掉了include（'testinclude.php'）。但是，一旦我包含該文件，患者信息中的所有數據都消失了，但程序列看起來不見了。我希望他們兩個都出現。

當我包含testinclude.php。這是結果：

enter image description here

testinclude.php

<? 

$id = '17'; 
//printf("<td align=left><font face=Verdana size=1 color=red>There are no Records</font></td>",$num); //prints number 

$procedures = "SELECT * FROM incurredcharges WHERE patient_no = '$id'"; 
$result = mysql_query($procedures ,$dbh2); 


    if (mysql_num_rows($result) >= 1){ 


      $procedures = "SELECT 
      `incurredcharges`.`procedure_no`, 
    `c`.`procedure` 

FROM 
    incurredcharges 
    INNER JOIN (
    SELECT `procedure`, `procedure_no` FROM `charges` 
    UNION ALL 
    SELECT `confinement`, `procedure_no` FROM `confinement` 
    UNION ALL 
    SELECT `service`, `procedure_no` FROM `ultrasound` 
) c ON `incurredcharges`.`procedure_no` = c.`procedure_no` 
WHERE `incurredcharges`.`patient_no` = '$id'"; 

      $result2 = mysql_query($procedures ,$dbh2); 


      echo "<p><table border=1 cellspacing=0 cellpadding=2 bordercolor=#000000 width=100%>"; 
      echo "<tr align=top> 
      <td class=topHeadrow5><b>Procedure #</b></td> 
      <td class=topHeadrow5><b>Charge Incurred</b></td></tr>"; 


     while($row = mysql_fetch_array($result2)){ 

        echo ' 
        <tr> 
         <td>'.$row[0].'</td> 
         <td>'.$row[1].'</td>'; 
         echo "</tr>"; 

     } 
     echo '</table>'; 
     } 
    else { 

     echo "<p><table border=1 cellspacing=0 cellpadding=2 bordercolor=#000000 width=100%>"; 
     echo "<tr align=top> 
     <td class=topHeadrow4><b>There are no Records</b></td></tr></table>"; 
     return false; 
     } 
?>

我已經使用的伎倆上連接多個數據庫。每個mysql_query，我指定了它對應的dtabase配置。但它仍然無法正常工作。

編輯：

OK我只是想移動包括（ 'testinclude.php'）在底部。和它工作。它顯示患者信息和程序..

但在我的官方代碼，它doesnt。

你必須創建link每個數據庫，並通過該鏈接查詢

$link1 = mysql_select_db('invoices', $dbh1); 
$link2 = mysql_select_db('hmis', $dbh2); 


$sql1 = mysql_query($query1,$link1); 
$sql2 = mysql_query($query2,$link2);

那就是我所做的。我看到每一個mysql_query，我添加了相應的數據庫連接，如'$ result = mysql_query（$ sql，$ dbh1）;' – user1967153

請參考下面的代碼，

$dbh1 = mysql_connect($hostname, $username, $password); 
$dbh2 = mysql_connect($hostname, $username, $password, true); 

mysql_select_db('database1', $dbh1); 
mysql_select_db('database2', $dbh2); 

Then to query database 1, do this: 

mysql_query('select * from tablename', $dbh1); 

and for database 2: 

mysql_query('select * from tablename', $dbh2);

我在兩個連接上添加了pconnect並且它仍然是相同的 – user1967153

正是我所做的。也許關於很長的代碼不會使它工作。但我嘗試了一個簡單的代碼，它的工作原理。但在我的它並沒有。請查看我發佈的代碼。每一個mysql_query，我都指定了connecton。 – user1967153

當打開第二MySQL連接，你需要通過5說法這是真的。

請參閱MySql的手冊，

resource mysql_connect (string $server, string $username, 
string $password, bool $new_link = false)

new_link
如果第二個電話是對mysql_connect（）使用相同的參數，沒有新的鏈接將被建立，而是鏈接已經打開的鏈接的標識符將被返回。 new_link參數修改了這個行爲，並且使得mysql_connect（）總是打開一個新的鏈接，即使mysql_connect（）之前被調用了相同的參數。在SQL安全模式下，該參數被忽略。

我希望這會有所幫助。
