I occasionally got QueuePool limit of size 5 overflow 10 reached.
I don't call session.close() after I don't need them. Because I think
GC will do that.
But now, it seems that I am losting connections somewhere.
Should I call session.close after I use them?
Should I use try.. finally... to

Hello,
I'm using PostgreSQL / SQLAlchemy 0.5.5 and I build my Table objects

I have a table which has a timestamptz column and when I try to insert a

I just tried :

instead of :

Hi,
I have a problem with an adjacency list table, my knowledge of DB
design is flakey at best so please bear with me in terminology and my
attempt at an explanation.
I have a table/class/mapping as follows (the DB is sqlite3):
invoices_table = Table('invoices', metadata,
Column('id',
you're looking for query.with_polymorphic(). see the mapping
documentation section on joined table inheritance for details.

There are two reasonable options for this, one is to select tuples of
group, user, task and join them together with appropriate conditions:
session.query(Group, User, Task).outerjoin(Group.users).outerjoin
((Task, (Task.user_id == User.id) ~Task.complete))
the other option is to create a new
use query.join(). its in the ORM tutorial.

Something like the following should work:
session.query(Position, func.sum(Stats.points)).join(Stats.league,
Player.position)\
.filter(Player.team == 'Some team').group_by(Position)

Print out your Table object, see if that column was defined as you
expected by reflect()

the mapping seems perfect to me. parent_invoice would only be None for
the actual parent. perhaps there's some issue with your usage. check
your SQL echoing to make sure things are as expected.
My bad, was using 5.0, not 5.5 - just upgraded and it works fine.
Thanks your quick respone, that is exactly what I was looking for.

Hello,
I'm writing a basic SQLAlchemy application, and have started to
explore the concept of unit testing in general and specifically with
nose.
Since I am new to both SQLAlchey and nose, I do not know where to
start.
Right now the app is at the point where:
1) The tables are defined with
client_id = 309
dbclient = session.query(dbclientclass).filter
(dbclientclass.client_id==client_id).one()
results in AttributeError: 'long' object has no attribute 'decode'
I tried just session.query(dbclientclass).all() and it results in the
same error.
my class looks as follows:

sounds like one of your column types is incorrect (and assuming
convert_unicode=True on engine). otherwise theres no way to know the
issue without a stack trace.

Yes, you are right. I checked my column types and there was one
incorrect column.
Thanks!

Hi, Allen!
You can use something like this (yeah, I know that it isn't
declarative in any way):
class Node(Base):
__tablename__ = 'node'
id = Column(Integer, primary_key=True)
parent_id = Column(ForeignKey('node.id'))
parent = relation(Node,

nose works by running python files and methods that contain the word 'test',
some people use nose to call their UnitTest objects. But you don't have to
do this, you can get up to speed by using assert x == y for example.
As 1 possible implementation, you can have setup() method in your test file
