Hi again, <snip next bug description> > > After analyzing oql-ojb.g grammar file we found that 'from' > clause doesn't > support object aliases at all. > > It means that we have not possibility to use multi tables in query and > accordingly operations with joins. >
The ojb-oql.g is based on the official oql.g to be found on www.odmg.org (http://www.odmg.org/files/oqlg.zip). This grammar does not match the EBNF found in the ODMG3.0 book! It also contained several bugs. We modified this grammar to produce ojb query objects. Please don't blame OJB for deficits of the official grammar! > > > Do you know if object aliases support will be implemented in > OJB ODMG, and > if yes, can you say approximately when it will be done? Currently nobody is working on OQL improvements and there are also no plan to work on it. Of course all help is welcome to complete the OQL implementation! > Is there any other way to resolve this issue using only ODMG API? As OQL is the only ODMG way to perform queries: No! As mentioned in my other mail: you can safely use PersistenceBroker queries in OJB ODMG applications. cheers, Thomas > > > Thanks, > > Nick > > > > > -- > To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
