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

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.
Thanks,

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.

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.

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.

Another doubt:
I have the following tables on my database:
create table B (

create table A (
ID INTEGER NOT NULL PRIMARY KEY,
B_ID INTEGER,
FOREIGN KEY (B_ID) REFERENCES B(ID)

OK, then I was analyzing the generated sdo graph when I execute the
Have you setup the relationship on your DAS config file ? Should look
something like the example below :
Relationship name=BDATA primaryKeyTable=A foreignKeyTable=B
many=true
KeyPair primaryKeyColumn=ID foreignKeyColumn=B_ID/

See more info around relationships on [1] and
Yes, you got the point Luciano...so the reason is that it's not yet
implemented on Convetion Over Configuration ; ).
Thanks
