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.

Cetin, thanks for the answer. I think I'm going your way, but I will not use GUIDs. I don't like them because of performance issues (in some informal testing I made, SQL selects where 20%-30% slower using 16 bytes GUIDs than 4 byte integers).
