Heh :-)
In 3.1 we have a nice mechanism for creating simple extension points of
Cayenne. I hope we'll start using that more to unwind these chains and allow
for easier extensibility. I guess community input and contributions should
become a driving force here.

Thanks Andrus, that got me going. I had to create six classes to add a
single word to a query! ;)
And fortunately that single word is the first one to be output, so in my
appendJoinSubtree() function I am simply outputting " INNER" and then
call super.appendJoinSubtree() for the rest. Would have
There's a tree of related objects involved. Check Oracle8Adapter and related
classes. It actually switches Cayenne back to joins in WHERE clause. The chain
of overridden objects goes like this:
Oracle8Adapter.getAction(..)
Oracle8ActionBuilder
Oracle8SelectAction
Oracle8JoinStack
Thanks for your answers. I would like to stick to version 3.1, so could
somebody give me a hint as to where to modify the JOIN syntax in a
custom DB adapter? I looked at all the existing DB adapters and I guess
I would subclass JdbcAdapter but I could not find a suitable method to
override.
Thank
Past versions of Cayenne used joins in WHERE clause, that were likely
compatible with MS Access. So older Cayenne 2.0.x should probably work.
Also writing a custom Access DbAdapter that adds INNER should be possible.
