Subject Re: [DAS Java] created SDO graph doubt
Date Wed, 04 Apr 2007 18:41:20 GMT
The RDB DAS will only populate a graph with data returned from the used 
query.  If you want a graph that contains data from related tables then 
the query provided must return that data (typically a join).  The 
relationship tests in the test suite demonstrate this.
