The following code is a simple reproduction of the issue.
# create your metadata and session
import sqlalchemy
table = sqlalchemy.Table (
'test_table', meta,
sqlalchemy.Column('id', sqlalchemy.Integer, primary_key=True),
sqlalchemy.Column('foo', sqlalchemy.Integer),
Hello,
I have a question about SQLAlchemy (well, I have a lot of questions,
but I'll try to space them out a bit!). I'm very new to it (and
python) but not databases and ORMs.
I like that I can use reflection to define tables, and I really want
to use that since I don't want to update pyth
Beautiful. I am impressed at the elegance of this sample and the

Hi-
I'm trying to add a deferred column to a declarative class after the

This works fine with none-deferred columns, as documented on
declarative.py:48, but deferred columns added in this way don't get
added to the table definitio
for SQLA integration you'd probably build this into the Session/Query,
which is most easily accomplished by subclassing Query. some examples
are in the distribution in examples/query_caching. I use a variant of the
"with_cache_key" version for my own purposes.
