Hi, I'm trying to learn a little about query optimization.. I have a query that is
pretty slow, and was wondering if there is an easy way to speed it up.

- sum((msgsize)/100) as mb,
- count(id) as count,
- avg(hits) as hits
will be in
all 5 product types.
I am trying to figure out the best way to optimize the relation ship between product
type and product.
if i create a product type table and then list each product in this type, i will have
close to 5 times the number of rows as i do number of products. since almost all
will be in
all 5 product types.
