Oh right, I'll do this . ( I was looking so hard on postgres features
that I forgot the python ones ... )
Thanks

I've got a small problem, I want to be able to join two related tables

The problem is that in the resulting SQL the tables are joined twice,

I have a problem with refresh, doing something along these lines:
object.subobject
object.otherviewofsubobject (this is actually a Firebird SQL view -
which I use for read only access)
do some update to subobject
session.flush()
refresh(object)
object.subobject
object.otherviewofsubobject
I'm trying to figure out how to add objects through the ORM. (My
schema and mappings are below.)
In the shell, I can do the following:
newQ = Question()
# ... set the attributes of newQ
mytype = session.query(QType).first()
mytype.my_sections
# correctly gives all the sections that belong to

Hello All,
I am facing a problem using the IN queries in sqlalchemy. I am using
sqlalchemy-0.4.5-py2.4.egg for the following.
The documentation at sqlalchemy.org states the following example for
showing IN queries
session.query(Address).filter(Address.email_address.in_(['[EMAIL PROTECTED]',

Thanks for the help
I was trying to make the code run on both 0.3.11 and 0.4, and hence
the error.
In 0.4.5 I can successfully call the following statements, and get

Tried that still no luck. If it helps any, the job_info table is
temporary and doesn't have any keys, or foreign keys, since it is being
constantly updated. So I am doing the join in my mapper:
qstat_mapper = mapper(JobInfo, qstat_table,
primary_key=[qstat_table.c.job_number], properties={

Sorry, both contains_eager and eagerload_all() work, however both
produce the same SQL, where both related tables are joined twice. They
both produce:
SELECT several columns here
FROM farm.qstatus
LEFT OUTER JOIN farm.chunk ON farm.chunk.queue_job_id =
farm.qstatus.job_number
LEFT OUTER JOIN
secondary_table = Table('secondary', Base.metadata,
Column('left_id', Integer, ForeignKey('parent.id'), nullable=False),
Column('right_id', Integer, ForeignKey('parent.id'), nullable=False))
class Parent(Base):
__tablename__ = 'parent'
id = Column(Integer, primary_key=True)

ah, my apologies, I was recommending a usage which has only been added
in 0.5.
