Hi,
If I create a table with a default.
create table T (id number primary key, data number default NULL)
Then reflect this table.
then using the ORM I trigger an insert, but only into the id column
and flush()
then I try to access the 'data' attribute
this causes a select, to get the actual
including small example
in the actual case, I can't find anything as obvious as the equivalent
of 'print t.data' in my code.. but something is triggering these
selects of columns with defaults
from sqlalchemy import MetaData, create_engine, Table, Column, Integer
from sqlalchemy.orm import
Hi,
I am looking for a way to store a non-sqlalchemy aware object in the
database, something like this:
class Foo(object):
def __init__(self, name):
self.__name = name
self.__map = {}
def set_name(self, name):
self.__name = name
def get_name(self):
Thank you so much. That worked. I was staring at the SQLsoup doc you
linked to for hours trying to understand but could not figure what the
_ meant. In any case your explanation is clear and very useful.
Thanks again.

what do you want p.data to return ?leaving it undefined is enough for the
ORM to consider it as unloaded. Your best option here would be just to not
map the column (see the exclude_columns argument for that).

I had read that, but it was unclear.
Initially I thought that scalar meant a single column. ie:
values(foo.bar) = ((17,),(18,)) ;

I'm encountering a problem with SA 0.6.1
I have a select statement which selects the same column twice (and
some other stuff, too).
However, when the query is run (or printed), the column only shows up once.
This seems like a bug.
Example:
from sqlalchemy import create_engine, select, Table,
not a bug, that's the correct behavior.

Thanks! It seems there's nothing SQLAlchemy can't do :).
Btw, since the examples are a bit complicated, here is just for

Can you explain how it is correct? I asked for two things but I only
got one. Why should it matter if they happen to be the /same/ thing?
In this particular case, I need it for
