首先，我已经知道不建议使用 mysql_connect，但是我没有时间学习 PDO 命令，一旦我首先解决了这个问题，我就会将其更改为 PDO。但是现在，我仍然无法在每个文件上合并两个具有不同数据库连接的代码。
<?php

上面代码的结果在上面的截图中。我注释掉了`include ('testinclude.php')。但是一旦我包含该文件，所有关于患者信息的数据都消失了，但程序列看起来消失了。我希望他们两个都出现。
当我包含 testinclude.php 时。这是结果:
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;
}
?>
我已经使用了连接多个数据库的技巧。每个 mysql_query，我都指定了它对应的数据库配置。但它仍然不起作用。
编辑:
好的，我只是尝试将 include('testinclude.php') 移动到底部。它奏效了。它显示了患者信息和程序..
但在我的官方代码中，它没有。
最佳答案
您必须为每个数据库创建链接并将该链接传递给查询
$link1 = mysql_select_db('invoices', $dbh1);
$link2 = mysql_select_db('hmis', $dbh2);
$sql1 = mysql_query($query1,$link1);
$sql2 = mysql_query($query2,$link2);
关于php - 连接 2 个不同的数据库不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14767455/
