    <p>I asked a similar question yesterday which may have been poorly worded, either way I didn't understand and this is something I really need to crack :) I've never done it before and would be very useful for so many of my projects.</p> <p>This is for a directory website. I have three tables: <strong>entry</strong>, <strong>location</strong>, and <strong>entry-locations</strong>. <strong>entry</strong> contains information about a building such as name, address, image, etc. <strong>location</strong> is simply a list of possible locations each building could be. The location table is pretty much irrelevant for this example, it just contains information about the location which I could display on other areas of the site.</p> <p><strong>entry-locations</strong> is a table which links the entries to the locations. It only has two fields, <em>entry-id</em> and <em>location</em>... If you're wondering why I need a seperate table for this is because the same building <em>could</em> have multiple locations (don't ask).</p> <p>Basically, what I need to do is display listings from each location it's own page. For example, I need to list every building in France, so the query needs to go through the <strong>entry-locations</strong> table returning every record with the location 'France', then it needs to pull all the data from the <strong>entry</strong> table corresponding to the <em>entry-id</em>'s returned.</p> <p>I'm sure there is a way to do this with one query and would be extremely greatful if I could be shown how, I could replicate this in so many projects.</p>

Querying!

 
Guidance
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.
