When I was using sqlalchemy 0.7.8 to manipulate database, it look's like
the query have some memory leak..I have googled this problem for a long
time, but no gains. I have tried run this snippet in a while loop. The code
eat 1M every 5 second. environment is Python 2.7.3, mysql 5.5.25a, fedora
Shouldn't open transactions within the session close when I issue a
session.remove()
I've also tried combinations of close, rollback and commit.
I do not work towards the cacheing in this service.
Does an open transaction mean I cannot issue any queries at all before
closing them? Because when

You can issue as many queries as you want at any time. the
Hi,

actually facing in a short sample here : https://gist.github.com/3499127

for this a

As a guess, I think this has to do with how scoped sessions work, but exactly
how they work is a bit of a mystery to me. Have you seen anything like this
behavior before?
I'm not quite sure how to investigate further into this issue, so
I was under the impression that the query property was implemented as part
of the scoped session (not the non-scoped variety) from reading the docs.
Is this not the case? If this isn't the case, I wonder if my issues will
just *go away* by switching the type of session I work with (while

Yes, this is the pattern I'm trying to describe though I've been thinking
of these as typed collections, smallish tables for handling a particular
table's collections needs, which are all of a single type (so rows are
either a collection or a FK to ONE other table). It feels very doable,
Well, you dug into a really esoteric and complex example there.
association_proxy is a much easier way to get around these cases where you want
an object to act like a scalar, so here's that, without all that crazy
boilerplate of the vertical example, which I'd avoid as it is really too
some of my sqlalchemy 0.7.3 (with tubrogears 2.1.4) models work with a
mssql 2005 db using pyodbc.
(No can't change this, don't bother suggesting, this is an enterprise
financial system, I can just read and write to certain tables there)
the query returned are encoded windows-1255 instead of
what ODBC driver ? the encoding issues are typically configured with ODBC.
it's a huge difference if you're on the windows drivers, vs. freetds, vs
anything else.
also I use MSSQL 2005 in production financial applications as well.
