at its most simplistic level, IN is just a bunch of X=Y joined
together via OR. Can that approach work here ? (seems like it would
be the best way considering its polymorphic scalar elements being
compared). At a higher level, seems like you'd want to group elements
of common types

is it the case that mxODBC only accepts DSNs and not TCP hosts as an
argument, but PyODBC accepts both ?

Hi Michael,
Thank you for the quick response. I had thought about using a
straightforward OR statement - are you suggesting that this would form
the body of the in_() method on the Comparator or were you referring
more to just compiling the OR statements in the base query?
Also, what is the
My previous description was a bit simplistic. Turns out the problem
only occurs when a join is involved.
See the following code:
###
from sqlalchemy import *
from sqlalchemy import orm
class One(object): pass
class Many(object): pass

Reading the docs for arraysize, its not clear if this only applies to
fetchone() and a non-arg fetchmany(), or to all fetches (I'm hoping
you have better detail on this.). If

Up to this point the default arraysize is 1 meaning that a single row

i am trying to generate an or_ clauselist and was wondering if i could
do so with a list comprehension, below is a small example of what i
first tried:
status = [1,2,3]
or_([users.c.status_id == item for item in status])
any ideas or tips would be great.
thanks,
Matt

you could use the in_ for this without looping over the list
eg:-
or_(users.c.status_id.in_(status))

Hey, i did a test included below with this output:
$ python cxotest.py

Setting arraysize to 500 before execution yields 0.26524348765
Setting arraysize to 1 after execution yields 25.8829982582

From reading the docs, it sounds like calling .close() on a session

When the Session is closed, it remains attached, but clears all of

So, I think i'll probably implement the patch I posted earlier and
actually default arraysize to 50, although I have a feeling it might
mess around with some of the BLOB-oriented functionality (since BLOBs
must be fetched at the point of receiving the row, else the cursor
moves on)..if
We're using SA 0.4.4. We're creating non-threadlocal sessions that are
bound to an engine at session factory creation time. Any ideas for why
even after closing one session and creating a new session with the
session factory that we're seeing old data? If we do an explicit
commit or rollback,
