parent = session.query(Node).get(1)
session.delete(parent)
session.commit()
In my case should raise the same IntegrityError.
Some hints ?

With SA 1.0.4 I can delete rows that i could not delete
to the stringall. This has the effect of entirely disabling SQLAlchemy’s
behavior of setting the foreign key column to NULL, and a DELETE will be
emitted for the parent row without any affect on the child row, even if the
child row is present in memory.

__tablename__ = 'part'
part = Column(String

in sqlalchemy 1.0 we do:
q.column_descriptions to get the query columns

This was working with release 0.9.9
Any idea how to fix it ?

Hi,
We are using sqlalchemy with Amazon Redshift. One of the things that I
wanted to do was to create a custom construct for Redshift's unload
statement. I modified the sample InsertFromSelect
(http://docs.sqlalchemy.org/en/rel_0_8/core/compiler.html?highlight=insertfromselect).
However, we

need to escape them in the query text. For example:
('select * from venue where venuestate=\'NV\'')

Hi,
I'm working with a client that does most of their work in stored procedures
on an oracle database. One of the things I'm trying to help them with is
transitioning to use sqlalchemy for calling said procedures.

you can run unittests against the sdk. there's a couple of setup things that
have to be done though. I use the NoseGAE plugin for it.
I don't think sql on gae is available in the sdk yet so there's not really
much that can be done at the moment.
When it does become available I'd be happy to
Is there an elegant way of replacing all the attributes of an instance,
except the primary key ?
Currently, I create a new object with all the date, fetch the old object
and do for k,v in new: old.__setattr__(k, v), taking care to skip the
primary key attribute. There's a custom __iter__ method
Sqlalchemy fits in nicely with pylons, turbogears 2, and repoze.bfg
and I'm sure many others. So you have options.
I wouldn't be able to offer any advice other than that, but spend a
few moments getting familiar with each and you'll probably reach some
conclusion.

Say we have a many-to-many relation:
mapper(Group, group_tbl,
properties={'users' : relation(User, secondary=group_user_tbl) }
)
group_user_tbl = Table('group_user', metadata,
Column('group_id', Integer, ForeignKey('group.group_id')),
Column('user_id', Integer,
17 matches
