Mike,
Very helpful! Seems to work great.
Wanna give me a tip on how to make the user's table join to this query
via the user_id so that I can access the user's information at
something like q.user.email?

1) Is there a way to give SqlSoup hints on how to handle the lack of a
primary key so that the selection and mapping magic will work
correctly instead of raising a PKNotFoundError exception?
SQLSoup tables are all mapped classes. a mapper() always needs a primary
key. so at
why not use a high speed database like an in-memory SQLite db for running
your tests ?

Hi all,
I'm having a problem with a non primary key sequence involved in a
relation. The failing environment is sqlalchemy 0.5.5 on ms sql server
2005 with pymssql 0.8.
I have a parent table with its own pk and a sequence field and a
child table with a pk composed by the parent's sequence (NOT

If we prefer it to be characters, then we should probably use
CHAR_LENGTH instead of DATA_LENGHT when reflecting, and add the CHAR
specifier to the column generators. I can put together a patch if that
helps.

Hi,
I'm trying to create a custom/derived attribute on a table class. This
is what I have defined:
class Plate(Base):
__tablename__ = 'plate'
__table_args__ = {'autoload' : True}
class Design(Base):
__tablename__ = 'design'
__table_args__ = {'autoload' : True}
OK, so is the solution to run these in separate processes instead?
Is this a GIL limitation?

Assuming a declarative based class USER exists, then you can join each of
the queries q1, q2, q3 to USER like this:
q1 = session.query(P1.userid,P1.extra,P1.title,P1.body,USER.email)
q1 = q1.join((USER,USER.userid==P1.userid))
q2 = session.query(P2.userid,'X',P2.title,P2.body,USER.email)
q2 =

I have two mapped classes (A and B) and want to create a union_all query.
q1 = session.query(A.data, '\'A\'') # includes a literal 'A' in the result

qry = q1.union_all(q2)
generates this SQL:
SELECT anon_1.data, 'A'

not at all. you would need to a. determine that you do in fact have
