2 tables one search


I have a problem, that effects my navigation system, I have three tables:

1 which lists all my product info



1 that is a contents map of all my navigation links



And one that sort of links the two


product_id (this is the same product_id the in the product_tbl)
product_link_id (this relates to one of the sub_id(number) in the navigation_tbl)

what i want to do is create a sql statement that when I have selected all the products I have, it will get all the links i need.

So i have a sql statement to get the products

select * from product_tbl which sport='football'

which will get all my products

but then I need to get the navigation ids relating to the products within that search from the category_tbl and then use that to get all the links from the navigation_tbl

Background is I have set it up like this as I need to add more than one category to each product and the old system I had was very processor heavy, so i am looking for a better way, and think this to be it.

Any advice would be appriciated, I am programming in asp and the DB is mysql.

Joining multiple tables   (91 Views)
Okay I have a MAIN table with two smaller tables which are just look-up tables in Access (eg unique-id and description) I want to JOIN the two to the main table so instead of showing the id numbers in output, it shows the description. I can "inner join" okay with one smaller table but I can't get ALL three going properly. SELECT * FROM org INNER JOIN orgloc ON org.orgtown = orgloc.orglocid INNER JOIN orgtype ON orgtype.orgtypeid = org.orgsector; org is the main table. orgloc and orgtype are the two lookups.

(you should not assume the parent_org_id in other tables also same as here.) can anybody help me out
