i went for polymorphic asociation on my multiple inheritances /
multiple aspects. it gives even more freedom than what strict
inheritance needs.
the examples around ruby-on-rails are for one2many/many2one:

Hi all,
I've been thinking about using mako as a sql templating engine to
dynamically generate sql. The reason for this is that recently I've
realized 90% of time is really spent on generating some kind of
analytic views (materialized into materialized views or tables) on
existing oracle tables.
Hi All,
I am doing some work with xmlrpc. One thing I realize is that whenever
I pass dict(row) through xmlrpc, I get an key-ordered struct. But this
isn't what i really want. What I want is ordered by insertion or the
original list order. This led me to look at the util.ordereddict
implementatio

The "eager load" feature of a relation(), which is responsible for

I was wondering if it is possible to set up joined table inheritance
so that a subclass inherits from more than one base table. To extend
the example given in the documentation, we would have a base class
'Employee' and a base class 'Citizen' such that an 'Engineer' would
inherit from both Employe
So what I am understanding is that right now, SA only does LEFT OUTER
JOINS? Or am I misunderstanding?
thanks,

Hi,
I need to interface with a couple of Views in Microsoft SQL Server
2000. How do I go about doing this with SqlAlchemy? Since a View
doesn't have columns per se, how do I go about creating a class and a
table object to map them?
I tried my Google-Fu, but there's not much out there on this sub

Hello,
I was wondering if there are any plans to have a csv engine for
sqlalchemy. I would like to see support for csv. There are some cases
where csv is the best way to convert data to and from especially when
they require cleaning. What I would like to see is a sqlalchemy
wrapping over csv modul

Michael,
I had thought that may be the case, so I had already started with the
databases/mssql.py file. Do you think that is the best place to
start? Is SA structured that all DB specific components are stored in
that location? Just trying to scope the effort from my end, any
thoughts are appr
Thanks! That's indeed the stuff I was looking for!

here is my code:
c_table = Table('campaign', metadata,
Column('id', Integer, primary_key=True),
Column('content', Unicode(200)),
)
m_table = Table('mailings', metadata,
Column('id', Integer, primary_key=True),

Hi all,
I just started playing with SQLAlchemy today (after several years of
plain SQL experience) and I must say I'm impressed. I'm reading my way
through the docs now, but there is one thing I can't seem to find. Let
me briefly explain the situation.
I was given the task of rewriting a databas
