I'm using the ORM and one of my tables does not have a primary key defined.
I am also using DeferredReflection, and I can't seem to figure out how to
defer the PrimaryKeyConstraint until Base.prepare() runs. Any pointers?
Base = declarative_base(cls=DeferredReflection)
class
and 0.9.

When I pass binary data to a multi-column in_ clause, I seem to be geting
inconsistent results and I need some help! I did some testing with MySQL,
Postgres, and Vertica (connecting via

I am having a bit of trouble getting DeferredReflection working the way I
want; not sure if I am overlooking something obvious or if I just don't
really understand how it's supposed to work.
I'm trying to define my models before creating my engine (this does not
work):

Interesting, thanks Michael. I didn't realize autoload was implied when
using DeferredReflection but that makes sense.
Thanks!

Ah okay, so you do recommend the contains_eager approach. I guess this is

I try using advanced features of SQLAlchemy :)
One last question. The query here
I'm building a pyramid application using pyramid_tm and
ZopeTransactionExtension. We've written a little subscriber on NewResponse
that writes out some values to a log file about the current user

Writing a big list of conditions and combining them with and_(*conditions)
worked well. I was indeed querying like this before:

I haven't boiled this down to a short test case yet, but when my WHERE
clause gets especially long I start getting the recursion depth exceeded
exception. Is this a well-known limitation of sqlalchemy? We're running
this query in production currently without SQLAlchemy, and it performs
fine,
