DB2 determines the updatability of a view soley by its' structure.
E.g. a view based on a JOIN is not updatable. The rules are describe )I
think) in teh CREATE VIEW statement. Search for "updatable view"
If you need to update such a "complex" views you can take a look at
INSTEAD OF TRIGGERs. Such a trigger defines a mapping from the view to
the base table (typically the reverse operation from the SELECT).
