Ok, so let me explain the problem we're facing. I'm using turbogears
with sqlalchemy. I run a custom query by supplying the SELECT string
to the engine and then execute() that. It returns back a list of
tuples. I'd like it to return a bunch of instances of A but I can't
seem to find the api
Sam,
Well, you can do MyClass.select(conditions) which returns instances. If you
only want to return a selection of comments, I believe there is a hook to do
that; check the docs.
I can understand this may seem strange to you, it certainly did to me in the
beginning, but as I built up experience
Hi all,
I have a Postgresql 8.2.4 table where more than one field auto-
increments. It looks like I need Passive defaults. Can someone show me
how to add passive defaults to an existing db schema, where
autoload=True. The doc glosses over this, and I can't pin down the
syntax.
Thank you,
Gloria
Dear list,
I'm trying to join a table with itself. That works well. However since
the column names are identical I had no luck accessing both the original
and the joined information.
I have aliased the tables already and run the join on the aliased names.
But the column names are still not

Hello,
Based on http://www.sqlalchemy.org/trac/ticket/435 and a perusal of
the source it seems to me that the sqlalchemy fetchall method with

has CLOBs or BLOBs. I

Hi,
With SQLAlchemy 0.3.8, I wanted to select from a many-to-many
relationship with ORM, and found that if the select condition contains
fields in the relation table, the relation table will be duplicated in
the select statement and thus leading to wrong results.
In the following example, I am

Thank you for your response. I tried posting this before, but it
failed. Hopefully it won't double-post.
I still get a can't adapt 'UPDATE... error. Here is the table from

Hi,
pyodbc, pymssql, and adodbapi each use binary modules, so they would
require some (unknown amount of) conversion to work with IronPython.
Actually, adodbapi is pure Python, although it does depend on the
win32com binary module.
I wrapped a module around the IPCE adaptor module to meet
The query to autoload foreign keys from the information schema views
on MS SQL Server performs very poorly for large databases. I extracted

this is a very old and unused feature that I should probably remove in

This worked, thank you for the quick response. The support here is
