MySQL - 多表选择

Question

好。所以这就是我想要做的。

products_description：
products_name | products_id

products_to_categories：
products_id | categories_id

categories_description：
categories_id | categories_name

基本上我想得到products_name，其中categories_name等于'Refurbished'（产生多行）。任何帮助将不胜感激。

Answer 1

    SELECT p.product_names

    FROM products_description p, products_to_categories pc, categories_description c

    WHERE p.products_id = pc.products_id

     AND pc.categories_id = c.categories_id

     AND c.categories_name = "Refurbished"
