Retrieve number of products per family per category
Hi there,
I have 3 tables
Categories
c_id,
c_name,
c_order
families
f_id,
f_name,
f_order,
f_category
products
p_id,
p_name,
p_price,
p_family
I need to retrieve families who got 1 or more products for all categories and list like this order by c_order,f_order.
<cfoutput group="c_name">
#c_name#<hr>
<cfoutput group="f_name">
#f_name# (number of products for this family)
</cfoutput>
</cfoutput>
Thanks in advance.

Can you define the key relationships among the three tables?
ASKER
f_category bind to c_id
p_family bind to f_id
p_family bind to f_id

I think that might work but should add "having count(p_id) > 1" at the end.
@awkinggoo - I don't think you need it. The inner join does that already. Categories w/o matching products are automatically dropped from the results. Everything else should have at least 1 product.

Thx a lot
Sorry, I misread >>need to retrieve families who got 1 or more products =<< as
need to retrieve families who got more than 1 product
need to retrieve families who got more than 1 product
