complex mysql query

I am trying to come up with a solution for my query below. heres my problem. the query below is on two tables. the second table "orders_products" can have multiple entries tied to the first table "orders". What I want to do is have a result that counts the sum of the entries in "orders_products" based on an extra id and returns those counts per row. For example.

orders contain the order_id and purchase date, and orders_products contain the products that were purchased with columns like order_id and product_id. I am trying to create a query that will report all products purchased within a timeframe and if any of the "product_id" match, count and combine those products into results per row. So my end result should look something like

row1 = sum of product_id1 - product_name1
row2 = sum of product_id2 - product name2.

heres what I have so far which basically returns every order within the date range.


$query = "SELECT o.*, op.*
FROM `orders` o, `orders_products op
WHERE o.orders_id = op.orders_id
AND date_purchased >= '2007-11-06'
AND date_purchased <= '2007-11-07'";
                                                                              
$data = mysql_query($query);
$rows = 0;
 while ($record = mysql_fetch_array($data) ) {
  $rows++;
  $records[] = $record;
}

You should perform a GROUP BY:

SELECT o.orders_id, o.date_purchased, SUM(op.orders_products_id) AS products_count
FROM `orders` o, `orders_products op
WHERE o.orders_id = op.orders_id
AND date_purchased >= '2007-11-06'
AND date_purchased <= '2007-11-07
GROUP BY o.orders_id, o.date_purchased

You can see the GROUP BY reference here: http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html

$query = "
SELECT op.product_id, count(product_id) as CountSold, p.product_name
FROM `orders` o, `orders_products` op, products p
WHERE o.orders_id = op.orders_id
AND p.product_id = op.product_id
AND date_purchased >= '2007-11-06'
AND date_purchased <= '2007-11-07'
group by op.product_id";

end up with this, i think the above would work as well so accepting.

SELECT products_id, count(products_id)
FROM orders_products
JOIN orders on (orders_products.orders_id = orders.orders_id)
WHERE orders.date_purchased between '2007-11-01' and '2007-11-07'
GROUP BY orders_products.products_id

the above DOESN't work.

SUM(op.orders_products_id) AS products_count

gives you ID+ID+ID+ID instead of counting them.. fffff
