Hi,
I've got some genome data, and I'm trying to move it into a db.
The data looks like
Patient FOOSNPBARSNP ...
Tom AA AT
John AT AA
...
These columns correspond to SNPS
We have been using the declarative successfully in our codebase for a
couple months now with 0.4.x, but we have just run into a problem.
We have a table we we want to map using declarative but we want to
have one of the columns be deferred because it contains binary data.
Unfortunately we can't

reflecttable is very monolithic. Breaking it down into smaller
components will make it easier to test. I follow you on adding
methods
to the Dialects and that seems like a good place for them.
I don't know
what kind of API

it doesn't know which class on the left side you'd like to join
from. so its looking for:
sess.query(A, B, C).join((B, A.bs), (C, B.cs))
alternatively, instead of A.bs etc. you can spell out the join
condition such as A.b_id==B.id in each tuple.

oh sorry, also count() is meant to count instances of a single kind of
object. So in fact you should be saying:
session.query(UserRss).join(Rss, item).count()

here's the new error message in the latest trunk:
InvalidRequestError: Can't issue count() for multiple types of objects
or columns. Construct the Query against a single element as the thing
to be counted, or for an actual row count use
Query(func.count(somecolumn)) or
Glad to known that it that simple.
Thanks

Found a few more and corrected.
You consistently spell propagate as

When reflecting a MSSQL table with a foreign key, the referenced table

Give the latest trunk a try and let me know. It should have been
corrected in r5266.
