[ http://issues.apache.org/jira/browse/OJB-16?page=comments#action_62713 ] Vadim Gritsenko commented on OJB-16: ------------------------------------
> Yes, but for OJB they are virtually identical: they > both want a list of (field) values of the current > object as input and return a resultset. That's why > I'd rather use one descriptor for these, where per > default the pks are used unless the user specifies > the fields (as arguments) himself. This emphasizes > the fact that all OJB does is to give the database > procedure some values from the current object > (or constants). Whether the database procedure then > uses them as pk values or something different, > doesn't matter to OJB as it is in the application domain. How then OJB will pick the right procedure out of the two?
