I everyone,
I have created a query in SQL, can anyone help me create it in relational algebra? I am trying to understand it.
SELECT Eats.name, Eats.pizza, Serves.price, Serves.pizzeria
FROM Serves INNER JOIN (Eats INNER JOIN Person ON Eats.name = Person.name) ON Serves.pizza = Eats.pizza
WHERE (((Eats.name)="amy") AND ((Serves.price)<10)) OR (((Eats.name)="fay") AND ((Serves.price)<10));
Thanks.
