when you map to a JOIN you must place all equivalent columns which you
would like populated identically in groups. This is described

How can i force sqlalchemy to refresh an object when i did a
session.query???
Sqlalchemy seems to work with a cache, i want to deal with it.
Nota : i use sqlalchemy in non transactional mode
Session = scoped_session(sessionmaker(autocommit=True, bind=engine))

Hi. Since docs for sqlalchemy isn't a clear doc for the beginners I
can't find out the way I could implement such a query:
SELECT extract(week from to_timestamp(min(datetimeinteger))) as min,
extract(week from to_timestamp(max(datetimeinteger))) as max from
logtable
Database is PGSQL.

Hi,
I have exactly the same schema in Postgresql, MySQL and Oracle.
I am reflecting the tables in my application using: self.meta.reflect
(bind=self.engine, schema='schem')
This works perfectly for MySQL and Postgresql but for Oracle I get no
tables reflected and cannot understand why. I can
I'm writing SA classes against a very unnormalized legacy database. Some of
our columns comprise several distinct values, and I wanted to take this
opportunity to split those into separate properties. I also wanted to be able
to search on the values in those properties, and here's my

Bonjour,
Tu es français je pense au vu de ton prénom.
Je continue donc en français.
En fait j'ai 25000 lignes de codes derrière moi et j'aimerai éviter d'avoir
à ajouter tous les refresh ou les session.query().populate_existing()
partout dans mon code
J'ai tenté en vain de surcharger la méthode

Nice guess.

Hi guys,
I have a couple of questions about a recent concurrency test I did on
SA. Someone in our team ran into a very intermittent issue where a
certain operation he tried doing failed by ConcurrentUpdateError. I
wrote a simple thread that can do query/update/insert/commit/rollback
operations

I also forgot to mention that you can always use query.delete() or
table.delete() to get a standard relational delete, though it does not
offer in-python cascading. This delete translates directly to DELETE with
the given
Thanks for the excellent information Michael. Will need to think about
this and post again if I have further questions.
As for the delete/rm discussion, I guess it depends on your use case.
I usually run rm with -f flag which fails silently if no file is
found. But I get your point and you also

Hi,
I'm trying to test my web.py app, including its database
functionality. I would like to use a test database for this purpose,
but it seems like the standard web.py way of doing things is to
hardcode the database connection in something like a config.py file.
What's the best way to test a
