[SOLVED] Joins not supported in Workspaces

Hi all,

I've followed the video as best I can but I keep getting the following error in my browser.

Unable to retrieve results: SQLSTATE[HY000]: General error: 1 RIGHT and FULL OUTER JOINs are not currently supported

When attempting to load a media item on details.php.

Any ideas?

<?php

function single_item_array($id) {

    include("connection.php");
    try {
          $results = $db->query("
            SELECT media_id, title, category, img, format, year, genre, publisher, isbn 
            FROM Media
            JOIN Genres ON Media.genre - Genres.genre_id,
            LEFT OUTER JOIN Books ON Media.media_id = Books.media_id
            WHERE Media.media_id = $id;

            ");


          //echo "Retrieved Results: ";
        } catch (Exception $e) {
          echo "Unable to retrieve results: ";
          echo $e->getMessage();
          exit;
        }



    $catalog = $results->fetch(PDO::FETCH_ASSOC);
    return $catalog;

}
?>

I've linked to a Workspaces snapshot.

This issue was purely to do with with the query i was attempting to use.

<?php
$results = $db->prepare("
            SELECT title, category, img, format, year, publisher, isbn, genre
            FROM Media
            JOIN Genres ON Media.genre_id = Genres.genre_id
            LEFT OUTER JOIN Books 
      ON Media.media_id = Books.media_id
            WHERE Media.media_id = ?"
                           );

?>

I also needed to stored it was a prepared query.
