This error comes from IBExpert, not from Firebird.

Without a proper way to identify the row, how do you expect IBExpert to
update the "right" one?

Imagine a shelf with 2 packages of cereal on them, you want to modify one
of them (take some cereal from it). Now, someone hands you over the
packages (you cannot see the shelf) and you want to "modify" the one that
was on the left. Which of these packages are you going to modify?

You can't tell, can you? :-)
