Updateable vuew

I am hoping to create an updatable view from two tables joined on two
fields. I have two questions;

1. How can I enforce a one to one relation in sql server 2005 based on two
fields? Do I need to create one explicitly under relations? Do I cerate an
index on both fields? Is there a step by step process I can look at to
create one-one relations?

2. Is a view updateable if there is a where clause on one of the fields in
the join/relation?

Thank again.

Regards

Please learn the columns are not fields. Basically an updatable view
must map one row in the view to one row the base table. That is not
possible with with a JOIN-ed table in general.

Use an INSTEAD OF trigger on such views.

I have the following situation: - a table of employees, keyed on employee-id; - a table of training sessions, keyed on session-id; - a requirement to log who was present at which session, plus optional extra textual information (e.g. "left early due to illness").
