That is pretty much what I expected. Considering it only occurs if the
developer writes incorrect code, I wouldn't want to make the performance
tradeoff.

Thanks, that helps. It looks like the problem is around a M:N relationship.
There is some complex logic about whether or not the row on the :N side of
the relation should be copied or the original referenced. The related
maintenance of the supporting association table causes the update problem.

I ran across this when writing some new code. I incorrectly appended
something to a relation and sent SA 0.5.6 off into an infinite loop until
max recursion depth was reached.
Obviously this is a coding bug on my part, but is it also a bug in SA that
should be fixed? I don't have access to 0.6 rig

since you got some help here, I'll also note that I was surprised I didn't
have "NOT IN" in the docs so I added that to the ORM tutorial.

In 0.6, dialects.oracle.base.NUMBER derives from types.Numeric and
types.Integer. In 0.5.3, I think the equivalent is
databases.oracle.OracleNumeric, which just derives from types.Numeric.
There's a separate databases.oracle.OracleInteger which just derives
from types.Integer.

Oops, those should both be issubclass, not issinstance.

And we have a winner. Always check you are actually passing the values
to the class constructor that you think you are before posting in a
public group, folks. I've think I've succeeded in humiliating myself
for today…

Hi all,
I know I'm probably missing something painfully obvious here, but here
goes anyway. I'm trying to create a table which has two foreign keys
to a different table, and failing miserably. I understand I'm supposed
to use the primaryjoin argument to relation… here's what I have in my

I don't use drizzle myself so I don't know how stable it is... but there
is DBAPI for drizzle...

Thanks a lot for the reply, definitely my code is looking better now.
