目前我正在尝试编写一个表达式，但我只知道如何在 SQl 语句中查询它

SQL:

SELECT * FROM Orders o
WHERE o.product_name != MBProductName
AND
o.transaction_id IN
(
SELECT m.transaction_id FROM marketBasket m WHERE m.product_name = MBProductName);

我想把结果做成表格形式的图表。

当我选择 MBProductName 时，它?葱写瞬檠?pb>

我不确de>MarketBasde> 表是如何填充的(也许您可以提供其中一些数据的示例)，但是，您可以使用所需字段创建一个直表，然后使用以下表达式作为数量总计：

1
=SUM({$<Product_Name-={$(=GetFieldSelections(MBProductName))}>} Quantity)

它的作用是获取您de>MBProductNde> 上所做的选择，然后在de>Quantde> 字段求和期间将其de>Product_Nde> 中的值中排除。作de>Product_Name = MBProductNde> 总和为零的条目，这些条目将从表中删除。
