Question

I have two tables, one with products and a foreign key for the customer. The other is a watchlist with the product id and the fk for the customer.

How would I go about looping the product information from the products table where the fk matches the session id in the watchlist?

My mind is blank and google isn’t helping!

Many thanks.

Answer 1

Example tables:

Products
--------
id (PK)
name
price
description


Customers
---------
id (PK)
firstName
lastName
email
phone


WatchList
---------
customerID (FK)
itemID (FK)

Get a customers watch list:

SELECT Products.name, Customers.email
FROM WatchList
JOIN Customers ON WatchList.customerID = Customers.ID
JOIN Products ON WatchList.itemID = Products.ID
WHERE Customers.ID = <insert customer id here>
