I "have" to put the code in the table just in case I don't use the view; so I thought that if I inserted the newId() in the view I would end up creating twice the PK (and wasting PK), but I tested and it was not the case. So I don't really know what should I do from a "good practices" point of view.

Creating the PK from the default value of the field, in the table, is quite simple. And, as far as I have seen, it works both in the table, and in the view based on the table.

I wouldn't define the PK in the view, precisely because you might want to open the table directly at some moment, and add records (interactively, or through a program).
