提取特定束产品订单

如何可以提取从下表中特定束产品订单。例如，如果我想提取产品Wireless Mouse已被用作捆绑产品的所有订单。提取特定束产品订单

期待结果1：

 
    orders_id  product_name  qty  
     1000  Wireless Mouse  1 
     1000  Laptop    1 
     1001  Wireless Mouse  3 
     1001  PC     3 
     1003  Wireless Mouse  4 
     1003  IPAD    4

第二个问题：

，如果我想只提取产品的订单，其与“无线鼠标”作为包我该怎么办呢？

期待结果2：

 
    orders_id  product_name  qty  
     1000  Laptop    1 
     1001  PC     3  
     1003  IPAD    4

如果可能的话，请帮我了解以下信息：

，如果我想提取它们与“无线鼠标”，仅使用“笔记本”的订单作为捆绑我该怎么做？

期待结果3：

 
    orders_id  product_name  qty  
     1000  Laptop    1

对于问题1

号正如你可以看到下面，查询嵌套。

子查询2获取其上有Wireless Mouse的所有orders_id。
子查询1个计数的每个Orders_ID其中Wireless Mouse是本记录的数目。
主查询从products_orders和products

 
Main Query 
    -- Subquery 1 
    --- Subquery 2

查询联接子查询。

SELECT aaa.orders_id, bbb.name, aaa.qty 
FROM  products_orders aaa 
     INNER JOIN products bbb 
      ON bbb.id = aaa.product_id 
     INNER JOIN 
      (
      SELECT aa.ORDERS_ID 
      FROM products_orders aa 
        INNER JOIN 
        (
         SELECT orders_id 
         FROM products_orders a 
           INNER JOIN products b 
           ON b.id = a.product_id 
         WHERE name = 'Wireless Mouse' 
        ) bb ON aa.orders_id = bb.orders_id 
      GROUP BY aa.ORDERS_ID 
      HAVING COUNT(*) > 1 
     ) ccc ON aaa.orders_id = ccc.orders_id 
ORDER BY aaa.orders_ID

对于题目2

从Question No 1，你可以在WHERE子句添加附加条件来筛选所有记录而不Wireless Mouse

... 
WHERE bbb.name <> 'Wireless Mouse'

查询，

SELECT aaa.orders_id, bbb.name, aaa.qty 
FROM  products_orders aaa 
     INNER JOIN products bbb 
      ON bbb.id = aaa.product_id 
     INNER JOIN 
      (
      SELECT aa.ORDERS_ID 
      FROM products_orders aa 
        INNER JOIN 
        (
         SELECT orders_id 
         FROM products_orders a 
           INNER JOIN products b 
           ON b.id = a.product_id 
         WHERE name = 'Wireless Mouse' 
        ) bb ON aa.orders_id = bb.orders_id 
      GROUP BY aa.ORDERS_ID 
      HAVING COUNT(*) > 1 
     ) ccc ON aaa.orders_id = ccc.orders_id 
WHERE bbb.name <> 'Wireless Mouse'

SQLFiddle Demo

对于题目3

就像问题2号，添加额外的条件

... 
WHERE bbb.name <> 'Wireless Mouse' AND 
     bbb.name = 'Laptop'

查询，

SELECT aaa.orders_id, bbb.name, aaa.qty 
FROM  products_orders aaa 
     INNER JOIN products bbb 
      ON bbb.id = aaa.product_id 
     INNER JOIN 
      (
      SELECT aa.ORDERS_ID 
      FROM products_orders aa 
        INNER JOIN 
        (
         SELECT orders_id 
         FROM products_orders a 
           INNER JOIN products b 
           ON b.id = a.product_id 
         WHERE name = 'Wireless Mouse' 
        ) bb ON aa.orders_id = bb.orders_id 
      GROUP BY aa.ORDERS_ID 
      HAVING COUNT(*) > 1 
     ) ccc ON aaa.orders_id = ccc.orders_id 
WHERE bbb.name <> 'Wireless Mouse' AND 
     bbb.name = 'Laptop'

感谢您的帮助。一件有趣的事是，我不知道<>是“不相等”。我今天从你那里学到了很多东西。再次感谢。 – Anam
