Vertical or horizontal? With vertical this will still select on

That's actually a good question. It will have to select against
the root, obviously, to pick up those attributes, but I don't
think it then calls all the other siblings if you call against a
leaf node, but I could be wrong about that.
No, it won't. I was just clarifying that it will still do two
selects to retrieve one EO.
If you're selecting on a leaf, I actually thought that EOF did the
right thing here and did a join of the leaf with the root and does
it in a single query.
Now that you say that, it sounds correct. It has been years since I
played with this.
If you select against the root, you will have to do leaf-many
queries, though, in both horizontal and vertical.
