Hmm maybe I'm missing something. Perhaps someone else can jump in,
and show me what I'm missing?
When I take your code, and execute the following 5 cases:
CASE A: no 'subquery' on relationship, 'subqueryload' on query
CASE B: 'subquery' on relationship, no 'subqueryload' on query
Morning Martin:
I could be wrong, but I think what you're looking for is lazy='joined'
rather than lazy='subquery'.
When I change the following, I see one query per showDatabase() call
rather than two.
class Men(Human):
myChildren = relationship('Child', secondary=link_table,
Hi John:
The following import is causing that error.
from sqlalchemy.orm import session, Session
In the all-in-one example you provided, you later go on to reassign
'session' and 'Session', replacing those imported values with your own
values.
Session =

Any ideas why I'm getting one row back with an id of 5 when I filtered
by id IS NULL?

Hi Chris:
I'm a bit hesitant to share what I've done, b/c it's still a work in
progress etc, but here goes:
MySQL MyISAM, wait_timeout=28800
SQLAlchemy 0.5.6, pool_recycle=3600
I've written a few decorators (mostly stolen from SQLAlchemy docs
examples):
def with_query_write(fn):
Yup, no transactions (legacy, can't switch anytime soon) which is why
I didn't originally write any rollback framing... but I was still
getting the following error after MySQL raised a 2006 (until app
restart), and a quick peek at _handle_dbapi_exception seemed to
suggest that I needed to issue
Yes, Congratulations Thank-you!

Thanks for the quick response, Michael.
We are mapping the classes dynamically, and we patched an in-house
copy of SQLAlchemy 0.5.6 with the stricter mutex from SQLAlchemy 0.6
to fix the sporadic mappers failed to compile errors we were seeing
under production load.
We also added a Least
A, deferred (new to me), thanks!
in sqlalchemy/test/orm/sharding/test_shard.py:
mapper(WeatherLocation, weather_locations, properties={
'reports':relation(Report, backref='location'),
'city': deferred(weather_locations.c.city),
})
When I comment
? Is there some way I
can optimize this case, perhaps by setting the shard_id somewhere, so
that 4 queries aren't executed in this case?
Thanks,

Thanks, Michael.
This will take me a bit to digest, and I'm about to start the second
shift as wife and mother... tomorrow maybe.
Thanks again for the quick responses -- greatly exceeding expectations!

Yup, I don't actually do this in a real app. I was just doing this (in

there's no issues within SQLA itself.
