Are you looking to arbitrarily update the field in the fifth row, or can the row that needs to be updated be isolated by some add'l attribute? What's the use case?
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?
