Hi there,

I have a table T with a column 'FooId' which is a foreign key to a table 'Foo'.
The 'Foo' table is the root of a table-per-subclasse hierarchy, with
two subclasses: xFoo and yFoo. The yFoo is actually a VIEW.
I have a statement inserting some thousands of T rows, some related to
a xFoo, some others to a yFoo.
I've noticed that an UPDATE on the yFoo view is automatically
executed, and I got this:

Update or insert of view or function 'yFoo' failed because it a
derived or constant field.

How can I avoid this?
Can anyone help me?

Thanks in advance,
Giulio
