Thanks a lot Hilmar.

What I don't understand is that I have surrogate primary keys for all my tables, and I indicate them to be the one who drive the updates in views.
It seems as if the SQL WHERE clause depends on how many fields you have to update, but the SYS(3055) function only talks about not having a primary key.
