I don't think the info I sent last night was particularly clear,
apologies it was late. The code for the classes is below:
# ArkClient - clientprojectshot module
orm.mapper(ArkClient, clients_table, properties={
'contacts':orm.relation(ArkContact,
backref='client'),
Sorry, for the spamming, code typo (was trying to simplify it), should read:
invoices = query(ArkInvoice).\
join(ArkInvoice.project).\
join(ArkProject.client).\
options(sa.orm.contains_eager(ArkInvoice.project.client)).\

Thank you for a quick response. It's much appreciated. Let me be more
specific:
1. Do you use the code provided in the above link? If not how do cache
and retrieve results via query.options() or cache.get() and then
session.merge() ?
2. Do you use it in any framework like pylons or diango?

Hi everyone!
Is it possible to have a many-to-one declarative relation between two
classes
Good fix, thanks.
And thanks for the first answer too, I had not thought of just using
__table__.c.discriminator. I was thinking I would need to use
sometable.c.discriminator, which I wasn't sure would work.
Incidentally, I'm finally going to quit using inheritance for cross-
cutting concerns
Hi,
I have a question:
Is it possible to get the information if an SQL Update was successful
from the Result-Proxy returned from executing the update statement:
result = connection.execute (update.where (pk_column == pk))
Thanks,

Dear Sirs,
My problem is following as follows I have multiple of queries that I
save in a list. When I have all my queires in the list I apply
intersect_all method
q=qlist[0].intersect_all(*qlist[1:])
I get my result simply by

Here's another issue with porting GeoAlchemy to SQLAlchemy 0.7.
So GeoA defines a TypeEngine, which looks like this:

Server defaults appear to be handled incorrectly in some cases (looks
like for string values) in versions 0.6 and 0.7. The code works in
0.5.
I run into this with sqlite, and don't have access other databases
right now.
Test case (code below):

I would think using declarative would solve most of it as the attributes are
defined explicitly on the class.
