excuse me if it sounds dumb... what about a middleman table of
This looks like a good solution. I'll need some time to provide a test
case, however.
If the change breaks existing code, how are cross-schema references
supposed to be handled?

The way to hook most parts of the ORM is by creating a MapperExtension

I have a mapper defined as
mapper(HierNode, HierTable, properties={
'tools' : relation(ToolNode),
})
Usually I am interested in iterating over all 'tools' and lazy loading
works fine. However sometimes I need to determine if one HierNode
has tools or not. Loading all tools would be too
shame on me I omit your ...addng the keyword parameter..., i.e.
db_mssql = create_engine( 'mssql://sa:[EMAIL PROTECTED]

unfortunately with scope identity it crashes earlier - mssql.py
returns None for id and rollbacks.

i have Links, pointing to Nodes.
Adding just Links to session + flush() works as expected - both Links
and Nodes got saved.
Doing session.close() although does not always detach all related
objects, i.e. sometimes some Nodes stay with _session_id on them
after session is long gone.

You added .all() when I wasn't looking? :)
