Hey, I have a problem. Namely, I have a form in which I choose the main key first (this way I want to mark which fields I want to edit in the following fields). Unfortunately, when I want to save the form, I am informed that the key already exists.
Solved! Go to Solution.

A key column value cannot occur more than once in the key column; no two rows can have the same key column value.
