It would be possible to support what you are asking but then the DAS
runtime would have to process and relate all the returned rows. I think
this work is better suited to the Database which is optimized for to do
this as part of a "join".

Hello Adriano,
To return a graph of related elements, the RDB DAS depends on the user
providing a Query that expresses the relationship between the elements.
This is most often done by providing a query that includes a join. See
the "relationship" examples in the DAS test suite.

Hi Guys,
The foreign key convention is supported and is demonstrated in this
test:ImpliedRelationshipTests.testAddNewOrder()
The convention is lightly documented here:

Interesting, I have a same scenario on a shoppingcart application I am
working on, and it does not work if I don't have the relationship defined on
my das config.

This is implemented. A column named {x}_ID where {x} is the primary
key table name is assumed to be a foreign key to a column named ID in
the PK table. Examples are in ImpliedRelationshipTests. I'm not sure
why it isn't working for you here, though.

Yes, you got the point Luciano...so the reason is that it's not yet
implemented on Convetion Over Configuration ; ).
Thanks

Have you setup the relationship on your DAS config file ? Should look

Now, if what you want is to have the relationship done via Convention over

Thanks Amita, I also debugged the code and took this conclusion. And I
wasn't sure if it's supposed to work this way.
Is there anybody that could confirm that it should work this way?

Hi Adriano,
Let me show what I got so far: Below is the debug dump and the relevant portion
of the logic will be in ResultSetProcessor and ResultSetRow. Based on
it, it is seen
that the parent/s attributes and data is not added. Please let me know
if you are
looking for something more/different.
Let me try to explain my doubt:
Lets suppose I create a select command and execute it. The returned
ResultSet has an attribute that belongs to the table X and is a FK to the
table Y, but no Y attribute is contained in the ResultSet. The question is:
does the das create, and also populate, the SDO
