Hi all,
I have several tables from which I have to fetch certain products &
categories based on customer selection. The tables are as follows:
Table 1 - Categories
catid (autonum)
catname
Table 2 - Sub categories
subcatid (autonum)
subcatname
Table 3 - Products
prodid (autonum)
prodname
Table 4 - Relationships
Catid
Subcatid
Prodid
Now, the question is how to fetch all the sub-categories let's say that
are related to category 0001. I know it's as simple as relating two
tables in one query, but I don't remember how. Any help appreciated.
