Answer 1

I think what you need is called a VIEW in SQL parlance. That is, a virtual table, created dynamically based on a SELECT statement. I would do it like this:

CREATE VIEW product_with_cat AS
SELECT p.Id, p.Name, c.Name as Category, c.Description as Category_desc
FROM products p INNER JOIN category c ON p.Category_id = c.Id;
