If you are looking for examples of advanced usage, dont bother with the book either - we just shelled out the $45 us and there are exactly 20 pages on the Java binding - 2 of which are about the properties file that OJB does not use. The rest is a very spec-like description, with a lot of "mays" and "depends on how you read it" phrases. For instance the doc implies that you must use the odmg collection classes (DCollection, etc) for any persistent 1 to many relationship, but does not specify this explicitly.
The book is somewhat usefull, but not for someone looking for advanced examples (which we were!). There is lots of stuff on the OQL, but you can find alot of that on the net (like the reference pointed to by Hai), but even that dosnt quite fit the OJB - the best example is this from the provided link SELECT x FROM persons x WHERE x.name = "Pat" OJB OQL does not support the aliasing (persons x) so the above has to be written as SELECT x FROM persons WHERE name = "Pat" Unfortunately we have searched extensively, and cannot find any good references for advanced ODMG/Java useage. > -----Original Message----- > From: Hoang, Hai [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, December 04, 2002 7:31 AM > To: 'OJB Users List' > Subject: RE: OJB > > > http://www.ccs.neu.edu/home/ylmao/oql/oql.html > > -----Original Message----- > From: Duma Rolando [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, December 04, 2002 7:58 AM > To: OJB Users List > Subject: OJB > > I'm using OJB in a project and i choose to use the ODMG APIs. > My problem is that I don't have the ODMG book and so I think > is very hard to > use all the OJB powerful features because of the OJB examples > are really > "examples" and not useful for an advanced usage. > Can you suggest me some docs on the net that can help in the > OJB/ODMG usage > or the only solution is to buy the ODMG book? > Sorry for my english, thank you for your answers. > > > -- > To unsubscribe, e-mail: > <mailto:[EMAIL PROTECTED]> > For additional commands, e-mail: > <mailto:[EMAIL PROTECTED]> > > > ______________________________________________________________ > ___________ > Introducing the all new and improved continental.com.
