Making the result set of a query involving more than one table updateable

I have joined two tables in a query on the first name and last name  (see attachment) . I plan to include this query in a form that will allow me to view the entries and make changes to them where applicable. The problem I am facing is that the result set from the query is not updateable. It only allows me to view the entries but not edit them. How can I remedy this situation?

To make that query updateable, you should be storing the Primary Key from the Applications table in the Statements table, and using that key field as the link between the two tables.

Try this...

Add a primary key to the Statements table.  (ID)
Include both primary keys in the query output.

See if that gives you an updateable result.

The primary key in both the tables is a combination of the first name and last name. You mean to say I have to have a single field as the primary key, and cannot use a combination of two fields?

I guess it is my fault...I did not specify it that way in the table design.

From your image, it looks like you have the ID field in the Applications table set as the primary key...  My suggestion was to add that as a foreign key to your other table and link on the ID instead of the two name fields (which you could then remove from the statements table).


Anyhow, try Pete's suggestion first.

If I made the primary key a combination of the first name and last name like so (see attached), it seems to work. The ID was just an autonumber created by Access which I did not use. I already have hundreds of records in each of the tables and don't feel like going in and assigning the matching ID from the Applications table to each of the records in the other two tables. Next time, though I will use a valid ID field as it will save me a lot of trouble that way.
