[Objectbridge-developers] newbie question: tree data structure, please HELP

[<joe...@ya...>]

Hi!

I'm a newbie with OBjectBride, and I have the
following  question:

Suppose you have a tree data structure composed of the
SAME classes
                     *
                -----|-------
                |           |
                *           *
There you have 3 classes (*)  and each class in the
tree has an attribute ID for the primary key.

To avoid 3 SQL statement to load the datas, you can
use the statement 'SELECT ...where id= .. or id=.. or
id=..'

Is this possible to use this king of optimisation with
objectBridge ???
Of you, transparently, otherwise it's like to code all
with the JDBC API.

Thanks
Joel
