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，它会返回错误的结果。我将列出下面的查询，以及相关数据库表/数据的样本（清理数据以删除客户信息）。

查询：

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))

原始查询过去是：

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。已排序的挂图没有属性，但在查询数据库时，它会应用为订单中其他项列出的属性。

相关数据的架构可在http://sqlfiddle.com/#!2/f0003找到我只在那里包含订单号23111的数据。

查询将结果传递给xml文件。结果如下：

应该是：

1个定制A5教师规划师|海军13.90 2.95
1个定制的A5教师规划师| DBI 3.30 0.00
1 NotesBook（NB）|海军3.50 0.00
1挂图2013-2014 0.90 0.00

提前感谢您提供任何帮助。

DRapp为此提供了一个几乎可行的解决方案，但是，尽管查询返回了正确的结果，但在使用中会产生问题，因为从结果调用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，那么它将不在orders_products_attributes表中，因此订单ID在这些产品上返回NULL，这意味着它们不会被后面的代码处理。

Answer 1

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先查询开始。确保您有一个索引来帮助优化。我会索引（ExportedToTradeBox，Orders_ID）。

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，但仅对加入它们的键执行（确保正确的订单和产品）。现在，您可以查询所有合格订单，并加入最终产品属性表，无论是否具有属性。

最后，将WHERE子句应用为NULL OR或者是您期望的类型之一。这样，它会查看每个项目并询问。如果没有选项，请允许它...但是，如果它有一个属性，我只想要那些选项为1或2（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 )

MySQL查询返回不正确的结果
