ok, but is there any document telling which functions are supported ?
And anyway do you encourage using OQL on OJB ?
I really would appreciate your opinion on this subject.

I have had a glance at the grammar, and it seems that most if not all of the OQL syntax is supported. Only a few functions seem to be missing (functions are something like 'count()' and the like). Other than that it is stable and works nicely. Also, we'll add the missing features in the, well, not so far future (thus making OJB fully OQL 3.0 compliant).


So if you consider ODMG as your API, then you should go ahead and use it. And if you have a query that currently does not work, you can always create a workaround with PB-style queries until the OQL implementation is fully OQL 3.0 compliant.

You're right, though. We should put together some documentation on the usage and available functions of OQL, especially because OQL is also usable from PB.
