Answer 1

sounds like you want to join across all tables:

select orders.id, orders.order_price, orders.purchase_date, customers.email,
    product_orders.qty, products.name from orders, customers, product_orders,
    products where
    orders.customer_id = customers.id and
    product_orders.order_id = orders.id and
    products.id = product_orders.product_id and
    products.id = 1
