医生和预约表

我有两张桌子；预约表和医生表。我想使用 Doctor_id 将 Doctor 表（姓名和房间）中的信息回显到 Appointment 表中。到目前为止，我的代码看起来像这样

约会.php

session_start();

您需要这样的查询：

selec * from Appointment ap
inner join Doctor doc
on (ap.Doctor_id=doc.Doctor_id)
where ap.Patient_id=$pid

然后，这一行：

$query = "SELECT Appointment_id, Doctor_id, Patient_id, Appointment_time, Appointment_date FROM Appointment where Patient_id=$pid";

应该换成这个：

$query = "selec * from Appointment ap      
         inner join Doctor doc
         on (ap.Doctor_id=doc.Doctor_id)
         where ap.Patient_id=$pid";
