cakePHP 3-如何在SELECT部分 中获取子查询

Question

有人对如何直接依赖CakePHP 3中主查询字段中的值的SELECT中的子查询有任何建议或经验吗？ 查询如下所示。

我正在尝试获取每个仓库中每个项目的OnHand值。我的物品和仓库清​​单将是动态的。一些用户可能会看到多达12个仓库和2K-3K物品。通过SQL查询，我可以获取一个包含每个项目包含3-12个元素的项目数组。一个很好的数组，可以轻松地循环显示。

我的查询对每个SQL有效。我收到约200个结果。我确定我已经以非蛋糕方式构建了子查询，但是我无法弄清楚如何在查询的选择部分内实现子查询。

我现在了解的问题不是直接与分页有关，而是与ResultSet（duh，错误消息从一开始就说）。我尝试了没有分页的查询。 稍后我会担心分页。只是

$query = $this->Inventory->Products->find('all', ['fields' => $select, 'conditions' => $conditions, 'order' => [$sort => $direction]]);

$ query-> all（），$ query-> toList（）和$ query-> first（）都产生相同的ResultSet错误。

CakePHP文档中的示例以及大多数（如果不是全部，我肯定我已经错过了某些东西，>>）示例）在堆栈的其他示例中显示查询的FROM或WHERE部分中的子查询或在表之间联接。

OR

我不正确地处理这个吗？我可以在不同的查询中获得相同的结果吗？

非常感谢所有帮助。谢谢。

$select[] = $this->Inventory->find()->select([$key => 'OnHand'])->where(['WhsCode' => $key, 'ItemCode' => 'Products.ItemCode']);
