Hi,
I'm wondering how I might get at postgresql's large object type (lob).
It's not to be confused with the TOASTED bytea, which are limited currently
to 1 GiB yet in practice is much lower (for me 400MiB) - it's a special
table + api designed to handle very large binary objects, like a few
Hello,
I am trying to use SQLAlchemy to map a database that was made available to
me, whose contents and schema cannot be altered. The database has a few
cases where a many-to-one relationship is treated as a many-to-many - that
is, instead of the child key being set directly onto the parent

I'm using sqlalchemy 0.8, python 2.7.6, rhel 6.5, oracle 10g,

yes you can apply the uselist=False option to the relationship.If
the relationship loads more than one row you'll get a warning.

Didn't say it was your responsibility, just thought you should know there might
be an issue there.
I'll modify the sequence manually and get back to it should the problem persist.

Just in case this wasn't apparent, you certainly *can* use psycopg2's
bindings when you're in an otherwise SQLAlchemy app. Worst case you can
retrieve a raw psycopg2 connection using connection.raw_connection and do
whatever you need. If you truly have some use for LOBs, SQLAlchemy isn't

For example, if you have two tables:
