INSERT INTO Supplied (CompanyID, ProductID, SuppID) VALUES ('C02', 'P01', 'S03');
INSERT INTO Supplied (CompanyID, ProductID, SuppID) VALUES ('C03', 'P02', 'S03');

SELECT
    C.CompanyName,
    P.ProductName,
    P.CostPrice
FROM
    Company AS C
JOIN
    Supplied AS S ON C.CompanyID = S.CompanyID
JOIN
    Product AS P ON S.ProductID = P.ProductID
JOIN
    Supplier AS Sup ON S.SuppID = Sup.SuppID
WHERE
