mysql - MySQL 查询返回不正确的结果

Question

我从这里得到了一些关于我需要的 SQL 查询的建议，但现在看来，如果遇到没有分配属性的产品，它会返回不正确的结果。我将在下面列出查询，以及相关数据库表/数据的示例（数据已清理以删除客户信息）。

询问：

SELECT * 
FROM orders_products_attributes oa
INNER JOIN orders_products op ON oa.orders_id = op.orders_id
WHERE (
products_options_id
IN ( 1, 2 ) 
AND oa.orders_id
IN (
SELECT DISTINCT o.orders_id
FROM orders o
WHERE o.ExportedToTradebox =  0
AND o.orders_id >  22000))

原来的查询曾经是：

SELECT * 
FROM orders_products 
WHERE orders_id 
IN
(
    SELECT DISTINCT orders_id 
    FROM orders 
    WHERE ExportedToTradebox='0' and orders_id >'0'
)

订单号 23111 是问题所在。订购的挂图没有属性，但是当查询数据库时，它会应用为订单中的其他项目列出的属性。

相关数据的架构可在http://sqlfiddle.com/#!2/f0003中找到，我只在其中包含了订单号 23111 的数据。

查询将结果传递给 xml 文件。结果如下所示：

应该是：

1 定制 A5 教师规划器|海军 13.90 2.95
1 定制 A5 教师规划器|DBI 3.30 0.00
1 笔记本(NB)|海军 3.50 0.00 1 挂图
2013-2014 0.90 0.00

提前感谢您对此的任何帮助。

DRapp 提供了一个几乎可行的解决方案，然而，尽管查询返回正确的结果，但在使用中它会产生问题，即从结果中调用 orders_id 不会为没有属性的产品提供订单 ID。这很可能是由表的连接方式引起的。如果产品没有属性，则它不会在 orders_products_attributes 表中，因此这些产品的订单 ID 返回 NULL，这意味着它们不会被后面的代码处理。

我会稍微调整一下。首先，从您想要包含的所有可能订单的预查询开始。确保您有一个索引来帮助优化。我会在（ExportedToTradeBox，Orders_ID）上有索引。

所以，现在我有一个“OnlyThese”的预查询结果集。现在，加入产品，因为所有订单都有产品，但所有产品都不需要属性选项。

然后，对订单产品属性表执行 LEFT-JOIN，但仅在连接它们的键上（确保正确的订单和产品）。所以现在，您可以查询所有符合条件的订单，并加入最终的产品属性表，无论是否有属性。

最后，将 WHERE 子句应用为 NULL 或作为您期望的类型之一。这样，它会查看每个项目并询问。如果没有选项，则允许它...但是，如果它确实具有属性，我只想要具有 1 或 2 选项的那些（通过 IN (1,2) 子句）。

SELECT 
      *  (actual column list you want) 
   FROM 
      ( SELECT DISTINCT o.orders_id
           FROM orders o
           WHERE o.ExportedToTradebox =  0
           AND o.orders_id >  22000) OnlyThese
         JOIN orders_products op 
            ON OnlyThese.orders_id = op.orders_id
            LEFT JOIN orders_products_attributes oa
               ON op.Orders_ID = oa.Orders_ID
               AND op.orders_products_id = oa.orders_products_id
   WHERE
         oa.products_options_id IS NULL
      OR oa.products_options_id IN ( 1, 2 )
