What do you mean?
I don't have any other attributes.

I want to understand how to emulate MS Access behavior, where you have a form with the arbitrary query, then you can go to any record in that form and update any field.

Is it even possible from the "pure SQL" POV? Or Access is doing some VBA/DB/4GL magic?


When you are updating a record in a form the framework(Access in your case) is using some identifier from that record to UPDATE that particular record in the database. From when I used Access, I seem to remember it would not give you INSERT/UPDATE capability on a form unless you had specified some unique key for the records. So you need to find what the key(generally a PRIMARY KEY) is and use that to do the UPDATE.

Thank you.
