title: MySQL Request only returning 1 row
body: <p>I am trying to get all the the fields from <code>appointments</code> while also getting the corresponding data from <code>zipcodes</code> using the following request:</p>
  
  <pre><code>select appointments.*, zipcodes.*
  from appointments
  inner join zipcodes on appointments.service_zipcode = zipcodes.zip
  where customer_id = {$_GET['id']}
  </code></pre>
  
  <p>The problem is that there are multiple appointments and I'm only getting 1 appointment back at a time. The join appears to be working as expected, but like I said, I'm only getting 1 row, rather than the 2 that are expected. </p>
  
  <p>Can someone tell me what I'm doing wrong? </p>
