A simple question:
I have a table with one HUGE column. Is there a way to make this column
lazy-loaded?

well, theres nothing that says the attribute youre sending in is
wrong. classes in python dont have any notion of predeclared
attribute names. a mapped class can have any number of other
attributes which dont correspond to database-mapped attributes.
in your case, you would like to constrain
i havent gotten around to adding docs for logging to the main
docs...but its using Python's logging module now. turn off all the
echo=True flags and go straight to logging:
import logging
logging.basicConfig() # see python's logging docs for options
Excellent. Thank you for the clarification.

yeah...if you want a schema level default, SA calls that a
PassiveDefault:
users = Table('users', meta,
Column('user_id', Integer, primary_key=True),

Hi,
The following program outputs 1; I thought it should output 0. Any comments?
from sqlalchemy import *
db = create_engine(sqlite:///:memory:)
metadata = BoundMetaData(db)
users = Table('users', metadata,
Column('user_id', Integer, primary_key=True),
Column('user_name', String))
You may want to turn on logging to see exactly what SQL is being issued:
try adding
import logging
logging.getLogger('sqlalchemy.engine').setLevel(logging.INFO)
to the top of your test script

every other line is a repr() of the bind parameter dictionary sent to
the query, so you probably want to grab those separately (they are sent
as distinct log lines - not sure why they are munged together in your
example above). the query itself is using bind parameters in
psycopg2's configured
Ahhh, that explains it. In my example, I had already removed the crud
at the beginning of each line.
For anyone else looking to do something similar, you can configure
postgres.conf to log the queries it recieves and I get the following
in the log file
:
LOG: statement: UPDATE students SET
