Michael, thanks, as ever, for your help.
So, I think I've managed to specify the relationships:
j = join(movies_table,md_table).join(directors_table).join(genres_table)
js = j.select(use_labels=True

OK, so I will treat any classes mapped to a join of multiple tables as

It doesn't look like I can define a relationship from the composite

A new problem, which seems to occur in both IronPython and normal Python:
I have a database with tables for movies, directors, genres (and a

I have a class mapped to a join of all three of the above

thanks for replying - the reason I attached a zipfile is because sqlite

print 'caught exception',e

how can i run the sqlalchemy test suite? I see it needs nose, i've
installed that. but i'm not clear what command to run to launch tests.

Hey,
a workaround i've used is is to manually set primary key to being a
composite of all columns if the table has no actual primary key. however,
this will mean that sqlalch ignores any duplicate rows, which you may not
want.

Not sure what the etiquette is re cross-posting to this list from
stackoverflow? here's my question:
http://stackoverflow.com/questions/3044518/how-do-i-take-advantage-of-sqlite-manifest-typing-type-affinity-using-sqlalchem
I like the idea of sqlite's manifest typing / type affinity:
if that was a
little arrogant?

Thanks Michael - i've seen others complain about the arbitrary-precision
numbers issue... I'm not so bothered by that, but i do like the ability to
natively store integers and strings in the same column.

Hi All,
I'm building a tool to extract info from databases. The
user/programmer doesn't have any advance knowledge of the structure of
the database before they load it, and i want to dynamically generate
mapped classes for the database.
i just want to check there isn't some helpful sqlalchemy
how do I run some self-testing in sqlalchemy? I found this doc, but
it seems to be out of date??
http://svn.sqlalchemy.org/sqlalchemy/trunk/README.unittests
just for fun, i'm trying to run these tests inside IronPython, so any
pointers in that direction would be helpful also..
thx,
HP
