Hello there. I'd like to use SQLalchemy with an existing db2 database
(I can already access it with plain SQL using pyODBC from a python-2.6/
win32 system).
Googling around, I found http://code.google.com/p/ibm-db and it seems
to have an updated DB-API driver for python-2.6/win32, but the latest

Not exactly. It says it maintains a connection for each SQL statement,

Hi Michael, hi *,
here is another issue I ran into with SQLAlchemy. Basically, I am trying
to map a filesystem like structure to SQL. Unfortunately, there is a
difference in that the users can reorder the tree. I reduced my code to
the attached example.
Mapping the structure worked quite good so

Hi All,
I am building a Pyramid app using SQLAlchemy for the model, and I
would like to be able to use the attributes as full-fledged objects
(i.e., I would like to be able to define methods attached to the
attributes), ideal example usage (although this is a somewhat
contrived example):

I have a typical case where I want to ensure that datetime values sent
to the database are UTC, and values read from the database come back
as offset-aware UTC times. I see several threads on the issue (eg:
http://goo.gl/FmdIJ is most relevant), but none address my question
that I can see. UTC
When I realized that process_bind_param only happens on commit, I
decided to switch my strategy to simply confirming that all incoming
outgoing datetime values are offset-aware UTC using this simpler code:
