I am not sure, but I think that is what I want. If it is of any help, I was
able to do this with what I would call a hack, and some temp tables, the
result is what I am after, however, I am not 100% happy with the method I
used.
// first make a selection of the data I want
CREATE TEMPORARY TABLE prod_report
SELECT p.id, oi.prod_name, sum(oi.quantity) as qty
FROM products as p
INNER JOIN order_items as oi
ON (p.id = oi.product_id)
INNER JOIN orders as o
ON (o.id = oi.order_id)
WHERE o.status NOT IN ('cancelled', 'pending', 'ghost')
AND
(o.created BETWEEN "2006-02-22 00:00:00" AND "2006-02-22 23:59:59")
GROUP BY oi.product_id
// select all products, set qty to '0', this fills in the gaps where there
// are zero item products
INSERT INTO prod_report (SELECT id, prod_name, 0 FROM products)
// re-seslect the real data, using group by to merge the duplicates
// out of the select
SELECT * FROM prod_report GROUP BY id ORDER BY prod_name
