Vertical or horizontal? With vertical this will still select on
the root, won't it?
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. If you select against the root, you will have to
do leaf-many queries, though, in both horizontal and vertical.
