Hello,
how is the progress with this feature - how can I use it? My
application strongly depends on AUTOINCREMENT being available.
To explain:
Without AUTOINCREMENT, a deleted primary key will be reassigned.

you'd have to roll that yourself. Its generally not feasable for
every relation on an object to be eagerloaded since it would create
too many joins.
I see, I'll just choose eager loads manually depending on context
then,

Hello everyone,
I want to find emails that have no projects added. 'projects' is an SQLA
collection in Email class.
So I have this:
unassocusers = session.query(Email).filter(Email.projects ==
[]).order_by(Email.email).all()
And I get this:
InvalidRequestError: Can't compare a collection
Hello everyone,
Found it, I have to do this:
unassocusers = session.query(Email).filter(Email.projects ==
None).order_by(Email.email).all()
Sorry for wasting bandwidth..

Hi.
Im still trying to use the select object from sqlalchemy, but i found a
strange (bug or not) behavior:
sql = select(columns=[self.fields], from_obj=self.tables,
whereclause=self.where, bind=self.req.cfg.engine, order_by= ' 1 ')
1) without order by, i get an error: AttributeError:
Hello everyone,
I have a table of Features. Simple enough for basic usage, but what if I
wanted Features to provide and require other Features? Akin to RedHat's
RPM packages that provide and require capabilities?
E.g. I would have AntiSpam feature that requires EmailServer feature and
because SurveySession extends from TreeNode, you have to disambiguate
SurveySession.id from TreeNode.id:
class SurveySession(TreeNode):
__tablename__ = session
__mapper_args__ = dict(polymorphic_identity=session)
survey_id = schema.Column('id', types.Integer(), primary_key=True,

Hi!
Here is a small (and not very useful) example to demonstrate the
problem. A table user contains a reference to itself (so that I
don't need a second table). This foreign key translates to a relation.
When I compare the corresponding attribute to null(), I get a
traceback. It all works if I
this indicates a None is being sent as a column somewhere.
I'm just not passing the order_by clause...
I dont see the SQLAlchemy expression you're dealing with here. the
symptom you describe is when placing a FROM object in the columns
clause of a SELECT, the object is also added to the FROM
How do I get the privileges for that?

Hello,
I have a stored procedure for SQL Server and I would like to be able
to execute the code to create the stored procedure using SA. Here's
the basic idea.
engine = sqlalchemy.create_engine('mssql://connectionString')
engine.execute(myStoredProcedure)
Where:

seems like a limitation of the DBAPI in use. have you tried creating
a test script using just raw (pyodbc | adodbapi | pymssql) ?

Hello all,
I have the following problem.
While I'm working in my session, someone change my instance identity.
I would like to avoid this.
Is there a way to understand if was there any change before flushing?
