Hi Guys,

The foreign key convention is supported and is demonstrated in this test: ImpliedRelationshipTests.testAddNewOrder()

The convention is lightly documented here: http://wiki.apache.org/ws/ConventionOverConfiguration

Thanks,

--Kevin

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"/>
   </Relationship>

See more info around relationships on [1] and [2].

Now, if what you want is to have the relationship done via Convention over
Configuration, I don't think we have that implemented, our set of
implemented conventions are limited at the moment.

Another doubt:

I have the following tables on my database:

create table B (
    ID INTEGER NOT NULL PRIMARY KEY
);

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 query
"select * from A, B;", I got something like this:

Graph1:

http://cwiki.apache.org/confluence/download/attachments/45093/das_graph.JPG

I understand the column B_ID would be considered only an integer column
when
of table A when there is no B table returned on the query. However, the B table is also returned on the query and as the B_ID column is a FK to the
table B, shouldn't the graph be like this?:

Graph2: http://cwiki.apache.org/confluence/download/attachments/45093/das+
graph+as+I+suppose+it+shoud+be.JPG
<
http://cwiki.apache.org/confluence/download/attachments/45093/das+graph+as+I+suppose+it+shoud+be.JPG
>

This way I think the data returned by the query would be better
represented
on the graph. Maybe there is a reason for the graph to be generated as
Graph1 instead of Graph2.
What do you say guys?
