根据另一个表对一个表数据进行排序

Question

我有两个表，我想从attribute_option表中选择所有行，并根据option_id表的product_attribute列对它们进行排序：

attribute_option

option_id | attribute_id  | option_name

     4    |       2       |  f1 

     5    |       2       |  f2

     9    |       2       |  f3 

    10    |       2       |  f4 

    17    |       2       |  f5 

    18    |       2       |  f6 

    24    |       2       |  f7 

product_attribute

rec_id | product_id  | attibute_id | option_id

   1   |      1      |      2      |  4

   2   |      1      |      2      |  5

   3   |      5      |      2      |  25

   4   |      5      |      2      |  4

---

对于产品ID 5 attribute_option 表应该是这样的

option_id | attribute_id  | option_name

    25    |       2       |  f8

     4    |       2       |  f1 

     5    |       2       |  f2

     9    |       2       |  f3 

    10    |       2       |  f4 

    17    |       2       |  f5 

    18    |       2       |  f6 

    24    |       2       |  f7 

Answer 1

SELECT attribute_option.option_id,
       attribute_option.attribute_id,
       attribute_option.option_name
FROM attribute_option,
     product_attribute
WHERE product_attribute.option_id = attribute_option.option_id
ORDER BY product_attribute.option_id

我认为这就是你要求的......

请检查一下。它完美地运作。准确提供您需要的输出。 http://sqlfiddle.com/#!2/e952e/4/0

SELECT attribute_option.option_id,
       attribute_option.attribute_id,
       attribute_option.option_name
FROM attribute_option,
     product_attribute
WHERE product_attribute.option_id = attribute_option.option_id
AND product_attribute.product_id = 5

UNION

SELECT attribute_option.option_id,
       attribute_option.attribute_id,
       attribute_option.option_name
FROM attribute_option,
     product_attribute
WHERE product_attribute.product_id != 5
