This is only possible if each order is uniquely assigned to one customer in the orders table. Alternatively, you can use another field called Customer_ID; however, to make sure that this field is not confused with the same field from the main form, the field is called Customer_Number.
子窗体应显示订单表格 (“Orders”) 中每个客户 ID 对应的数据 (Customer_ID - > x)。前提是，订单表格中的每个订单仅对应一个客户。也可以使用另一个名为 Customer_ID 的字段。但是，为了避免与主窗体中的 Customer_ID 字段混淆，可以将它命名为 Customer_Number。
