Hello,
Is there a way to tell the session to force load all the attributes of an
object during a query? (i,e even if it is already present in the Identity
Map?).
For some reason, auto_expire_on_commit, if set to True is not working well
with my app. I always do a session.query(object) before
Hi everyone,
I have an unusual situation where I have a set of users that are
stored in an SQL DB as usual, and a set of news articles that are
stored elsewhere (not in an SQL database).
Usually, if both sets were stored in two DB tables, I'd be able to set
up a many-to-many relationship with
Not sure about append, but you can definitely use column_property for
generated select property, more details here:

Hi All,
My application uses XML schema to load tables, classes, set SQLA
mapping and relations.
Each processing node (thread or process, depends on config) does not
know beforehand what type of mapping it will process, that's why I
need to create mapping (parse schema, and generate classes) per
What is the best way to populate an app with data, for base data and
test data purposes?
Is there an easy way to maintain some XML files with the base and
tests data? or is it the best way to just have a python script with
the data hard coded into it?

Hey guys - I've ran into a strange bug in 0.4.7p1 while trying to make
use of Elixir's versioned plugin. In Oracle, given a table created as
such:
CREATE TABLE books
(book_id NUMBER PRIMARY KEY);
The following code fails:
dbEng = create_engine(oracle://:@pearl)
meta = MetaData()
meta.bind =
Thanks for such a detailed response!
I'll try schema caching approach and will bring back the results,
Thanks again,

This is the expected behavior. SQLA operates in a case sensitive
fashion whenever a table or column identifier is given in mixed case
or upper case. Use all lower case for case insensitive. Since
SQLA seeks to provide a database-agnostic API to the backend, this
includes Oracle as
Hi Alex,
Thanks a lot for your help! This is exactly what I needed. I almost
gave it up before and started to write plain SQL to get the desired
results ;)
Works like a charm now. In case anyone interested, I am pasting the
results below (BTW it's an interface to a (custom) table from Roundup
Thanks for the answer, Mike. I was used to Oracle's behavior while writing
raw SQL, in which the case of unquoted column identifiers doesn't matter.
This behavior seems reasonable enough, although the inconsistency between
the cursor description and SQLA's column identifiers could throw some
Hi everyone!
I'm new to SQLAlchemy and I'm using version 0.5rc1..
I need every entity class to have a few common fields, so I tried
writing an abstract base class, declarative-style, that every other
entity class would subclass. So for example:
---
from sqlalchemy.ext.declarative import
i dont know if elixir has such 'attribute/behaviour injectors', i have
DBCOOK_no_mapping=True in dbcook.sf.net that does that. the machinery
behdin it is soewhat tricky (x in class.__dict__ and not in
base_class.__dict__ etc stuff)
u may try your stuff as mixin, that may or may not work.

I don't know whether this is currently possible with Declarative or
not. In the case it isn't, patching Declarative should be quite easy
(but I don't know if such a patch would be accepted or not).
I see.. I'll wait a bit then, maybe one of the developers will tell us
if it'd be acceptable :)

One of the recommendations for MySQL is to keep the password in
