Hi,
I have two tables (mysql).

One: "regions" with the fields "region_id" and "region"
Two: "objects" with the fields "ID"; "region_id" and "properties".
Every object belongs to a specific region (linked by region_id).

Now I want a list of all my regions sorted by, and displaying, how many objects belong to every specific region.

Can anyone help me with this one?
Thanks Dennis

SELECT r.region, COUNT(o.ID)
FROM regions AS r
LEFT JOIN objects AS o ON ( o.region_id = r.region_id )
GROUP BY r.region_id

Seriously... if people don't start reading this before posting, I'm going to consider not answering at all.
