Hi
SORRY for the delay to reply.
Here is what my definitions.
These are my class and table definitions:
class Task(DeclarativeBase):
task_id = Column(Integer,Sequence('id_
seq'), primary_key=True)
task_type = Column(Unicode(50), default=to_unicode('Task'))
name =
Hi
task = Task(u'Task',\
{'quiet':False}, [], {}, None, u'admin')
model.DBSession.merge(task)
in my database the following query will try to select the above task
object and result in error
DBSession.query(TaskCalendar).options(eagerload('task')).\

This thread is of interest to me as well, although the problem I'm
facing is somewhat different. Just to expand the space a little, here's
my situation:
- A legacy database schema with hundreds of tables and procedures.
- An application that accesses the database, with occasional updates

This is what is causing the error:

then it seems like either that fails directly, or it fails when the client
gets a hold of it. See what happens with that statement. Not sure that
Oracle 8 has NVARCHAR which might be the issue.
Please see the

There is a fairly short Oracle-published white paper on Unicode
support here:
http://www.oracle.com/technology/tech/globalization/pdf/TWP_AppDev_Unicode_10gR2.pdf
It does state that starting with Oracle7 there was Unicode support and
lists a table of Oracle version, Character set and Unicode
Don't use None for the Column type (i.e., detected as the null type). Put
the type explicitly. This has been updated in the documentation recently
since the None feature can't be fully supported at this time.

It specifically says NCHAR is not usable *for unicode* until Oracle
9i. (Showing my ignorance here: are you certain NVARCHAR2 uses
NCHAR? Seems logical to me.)
The white paper further states: No Unicode character set is supported
as the national character set prior to Oracle 9i. I believe the
latest patch - also try not specifiying use_ansi=False, it should detect that
now

I found a similar thread from about a year ago (http://

most burning question: is there a way in sqlalchemy to do a multiple
insert with default values for unspecified
attached is a test program that is of a format which allows us to be able to
answer your questions quickly. It is a short test program that runs fully,
using the model fragments you've sent along.
It does not reproduce your error. Instead, it appears that the is not an

not sure what the question is - how to use server-side defaults ?Column

of the columns dictionary for those columns where you want the server_default

My apologies; I expressed my question rather incoherently.
if the question is, I want to multiple insert like [{'a':1, 'b':2, 'c':3},
