Sql MSAccess子数据表

我有一个Access查询，在子数据表中列出发票和相关项目：

SELECT DISTINCTROW OutgoingInvoice.InvoiceID, OutgoingInvoice.Sum, OutgoingInvoice.Complete, Sum(Products.IncomingSUM) AS [Sum Of Products_SUM], [OutgoingInvoice].[Sum]-[Sum Of Products_SUM] AS Különbözet, OutgoingInvoice.Note, OutgoingInvoice.ID
FROM OutgoingInvoice INNER JOIN Products ON OutgoingInvoice.[ID] = Products.[OutgoingInvoice]
GROUP BY OutgoingInvoice.InvoiceID, OutgoingInvoice.Sum, OutgoingInvoice.Complete, OutgoingInvoice.Note, OutgoingInvoice.ID;

问题在于，没有显示项目的发票：

---

如何显示OutgoingInvice中的所有行（即使它们没有加入子项）

使用

DISTINCT

和

GROUP BY

始终可以推断您的聚合有问题<代码>分组依据将为每个不同的组提供一行，因此除非您的

分组依据

错误，否则

不同的

应该是多余的。使用左或右连接，而不是内部连接。ms-access不使用t-SQL。感谢您的帮助！由access生成的查询，但我删除了DISTINTROW。当然，左键连接是解决方案，谢谢！还有一个问题：我只能编辑子数据表中的文件。是否也可以编辑主查询字段？（错误消息：“此记录集不可更新”）

SELECT OutgoingInvoice.InvoiceID,
       OutgoingInvoice.Sum,
       OutgoingInvoice.Complete,
       Sum(Products.IncomingSUM) AS [Sum Of Products_SUM],
