I have put a self contained script that can probably reproduce this
for you. I think that the argument 'connect_args': {'autocommit' :
True } is causing the transactions to not work properly. Is this
expected and if so can you explain the reason. Thanks in advance.
Hi everybody,
(fast start :) )
I have a class hierarchy and I'm using joined table inheritance, but my
classes are not always going to be used with SQLAlchemy (or I plan to give
the freedom to people to use these classes anywhere they want).
Anyway I was using the entity_type column in my base
Hi all,
Newbie here.
I just want to execute the following sql using SqlAlchemy . But
getting various errors.
select ssf.factor,ssf.displayname,pmw.weight
from probability_models_weights pmw
inner join probability_models pm on pm.id = pmw.model_id
inner join success_factors ssf on ssf.id =
that is absolutely the reason transactions would not be working for you.
autocommit on the DBAPI essentially makes the commit() and rollback() methods
of the DBAPI connection a no-op.

Hi all,
It doesn't do the second filter with those queries:
session.query(User).options(joinedload(channels)).filter(User.id ==
int(userId)).filter(Channel.title !=
zeptextstuff.txt).order_by(Channel.titleView).first()
or
session.query(User).join(User.channels).filter(User.id ==
you want to use query.join() here, not joinedload.

I'm trying to build a MySQL-PostgreSQL migration tool that reflects tables
from MySQL, then creates them in pg.
So far so good, except that when SQLAlchemy reflects a MySQL table with a
DATETIME column, it reflects it as a sqlalchemy.types.DATETIME, then tries
to create a DATETIME in PostgreSQL.

Probably a very simple question. I use the ORM for inserts, with
postgres 8.3. How can I get the ids resulting from my inserts'
RETURNING clauses? I haven't been able to find the information in the
doc.
Thanks a lot,

Ultimately you have to modify the reflected tables or rewrite them using data
types that are appropriate to the target database. Reflection is in fact
going to produce the most specific type possible, so in this case you're
actually getting sqlalchemy.dialects.mysql.VARCHAR objects and such

Hi All
We need to connect to a Progress database, and we are in the very early
days of this. I understand it supports an ODBC interface and therefore should
be able to be connected to using SA - correct?
Are there any limitations on the ODBC connector or gotcha's that we should
look out for?

pyodbc works very well, as does mxodbc which is commercial. Most issues have
to do with using ODBC from unix, where if we're working for free we use
FreeTDS, that has a lot of quirks. There are commercial ODBC drivers for unix
