    <p>I have a car booking system database that i am in the process of building. I have 3 tables:</p> <p>car_table:</p> <pre><code>ID | car_make | car_name 1 | Ford | Focus 2 | BMW | Z3 3 | Audi | A5 </code></pre> <p>booking_table:</p> <pre><code>booking_ID | booking_time | total_cost | etc.. 125674 | 2013-02-02 | 91.55 887463 | 2013-01-19 | 52.00 209930 | 2013-01-11 | 23.99 </code></pre> <p>reservation_table:</p> <pre><code>ID | booking_ID | car_ID 1 | 125674 | 2 2 | 887463 | 2 3 | 209930 | 1 </code></pre> <p>So the reservation_table links the cars with the bookings. Now i am wanting to output the following result in a table for the user:</p> <pre><code>booking_ID | booking_time | total_cost | car_ID | car_make | car_model </code></pre> <p>How can i output the results for this, so far i have this almost working:</p> <pre><code>$query = " SELECT booking_ID, total_cost, booking_time, customer_ID, car_ID FROM bookings_table as bb, reservation_table as br WHERE bb.booking_ID = br.booking_ID AND payment_success=true ORDER BY booking_ID desc LIMIT 10 "; try { $stmt = DB::get()-&gt;prepare($query); $stmt-&gt;execute(); $rows = $stmt-&gt;fetchAll(); } catch(PDOException $ex) { // Failed } foreach($rows as $row): &lt;td&gt;'.$row['booking_ID'].'&lt;/td&gt; etc... endforeach; </code></pre> <p>Which displays as below:</p> <pre><code>booking_ID | booking_time | total_cost | car_ID | car_make | car_model 125674 | 2013-02-02 | 91.55 | 2 | | </code></pre> <p>So i can get the car_ID from the reservation_table but i don't know how i can also pull out the car_make/model by taking the car_ID from the reservation_table.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
