View and primary key

I don't think so at this time. Even if you got past that, I think the
index creation would fail saying that the view wasn't a table.

Nope, you can't have constraints on views. Typically what I've done with
similar things is to (1) make sure the column is a primary key in the
underlying table and (2) manually tell the tool the column in the view
is a primary key. I'd assume OpenOffice has some way to do that.
