您将需要JOIN表，如下所示:

You will need to JOIN the tables, like this:

SELECT products.description, orders.quantity, orders.price
FROM detail_orders
  INNER JOIN products ON (products.prod_id = detail_orders.prod_id)
  INNER JOIN orders ON (orders.id = detail_orders.or_id)

如果要查询特定用户:

    SELECT products.description, orders.quantity, orders.price
    FROM detail_orders
      INNER JOIN products ON (products.prod_id = detail_orders.prod_id)
      INNER JOIN orders ON (orders.id = detail_orders.or_id)
    WHERE orders.iduser = someUser
