remove all references.

[Vagula <Va...@infosys.com>]

Hi All,



            I have a table A which references tables B & C.

            The auto-retrieve of B & C has been set to true.

            While I retrieve a record from table A can I some how stop
the auto-retrieval of B & C.

           





Thanks and Regards,

Vagula

Currently it's *not* possible to change the object metadata at runtime 
in a per session/query manner (there are plans to make this possible in 
further versions).

Alternative, if possible use proxies for your references. In this case 
OJB will never load referenced objects on retrieve. From OJB 1.0.4 
cglib-proxies can be used (OJB.properties file setting) and you only 
need to set attribute 'proxy' in reference-descriptor and 
collection-descriptor to true (no need to define interfaces for all 
referenced classes).

Or you disable auto-retrieve and use PB.retrieveAllReferences(...). But 
take care of side effects.
