saving records from 2 tables with one to many relationship

[rwahdan1978]

Hi

I have 2 tables (customers and invoices), one customer will have many invoices. In a form I have added the user and the invoice details and I have a button to save the data, how to do that with VBA sql?

Username: ramiwahdan
Invoice#:1234
Date: 17-8-2024
Payment Amount: 200

where username is in one table and others in 2nd table.

Which table are you storing username? In the customer table implies all invoices are to be credited to the customer ( but doesn’t look like you specify a customer). If in the invoice table, implies username is the person who entered the invoice

so really not enough information to advise.

Can you upload your database?

Hi

Your Form "Invoice" does not make much sense.

Normal construction is that you would have a Main Form based on your table "Users"
with a subform based on the table "Invoice"

Your table "Invoice" has a PK set as Shorttext and it should be an Autonumber.

You should not be setting a Format on the field "Payment1", this should just be a Currency DataType.
