MySQL分组以查找唯一的组合

首先，我为这个模糊的标题道歉，我真的不知道如何表达它，我想这就是为什么我还没有找到解决办法的原因

使用修改后的OSCommerce安装，我试图在自定义报告的表中找到订购产品选项/属性的唯一组合。产品的每个选项/属性都存储在一行中。一个产品可以（而且确实）有多个选项/属性

我有以下SQL查询

SELECT
sum(op.products_quantity) AS attrCnt,
opa.products_options AS prodOption,
opa.products_options_values AS prodOptionValue
FROM
store_orders_products_attributes opa
LEFT JOIN store_orders o ON o.orders_id = opa.orders_id
LEFT JOIN store_orders_products op ON op.orders_products_id = opa.orders_products_id
WHERE
o.customers_id = '99999'
AND (o.date_purchased BETWEEN CAST('2017-01-03' AS DATE)
AND CAST('2017-02-01' AS DATE))
AND op.products_id = 88888
GROUP BY
opa.products_options_values
ORDER BY
opa.products_options,
opa.products_options_values

返回：

+---------+---------------+-----------------+
| attrCnt |  prodOption   | prodOptionValue |
+---------+---------------+-----------------+
|       6 | Select Colour | Blue            |
|       1 | Select Colour | Yellow          |
|       1 | Select Size   | L               |
|       2 | Select Size   | M               |
|       4 | Select Size   | S               |
+---------+---------------+-----------------+

在此期间订购的产品总数为7件，1件大的，2件中的，4件小的，-6件蓝的，1件黄的。从这一点我无法判断L（大）是蓝色还是黄色等

我想要的结果如下（无论是L-蓝色还是蓝色-L都不重要）：

包含此信息的表是存储\订单\产品\属性：

“产品选项”列可以包含任何分类文本分组（自由文本），例如“选择味道”、“选择xyz”等，因此它不总是颜色/大小

每个产品也不总是有两个选项，可以是0、1、12或更多

有什么想法吗

要开始，请使用此子查询而不是原始表：

(
select a1.orders_id,
       a1.products_options_values as sizeval, 
       a2.products_options_values as colourval
from store_orders_products_attributes a1
inner join store_orders_products_attributes a2
  on a1.orders_id = a2.orders_id
where a1.products_options = 'Size'
and a2.products_options = 'Colour' --  Yay, another brit
) x1

我不明白为什么他们在同一列（产品选项值）中存储两个不同的属性（颜色和大小），这不是一个概念问题吗？@mounaim你必须和OSCommerce的原始创建者Harald Ponce de Leon谈谈。在订购产品之前，信息以类似的方式存储，因此他们在订购后以类似的方式保存信息。选项可以有不同的定价/重量+/-money kg等。订单显示为产品名称--选择颜色=蓝色--选择大小=L，以这种方式存储数据。@mounaim还可以选择数量不受限制的选项，如果大小、颜色、xyz等有自己的列，则可能有100个列great idea，然而，很抱歉，我应该在最初的帖子中说，产品选项可以包含客户输入的任何分类、选择风味、选择容量等

(
select a1.orders_id,
       a1.products_options_values as sizeval, 
       a2.products_options_values as colourval
from store_orders_products_attributes a1
inner join store_orders_products_attributes a2
  on a1.orders_id = a2.orders_id
where a1.products_options = 'Size'
and a2.products_options = 'Colour' --  Yay, another brit
) x1
