I'd like to map a class onto table and automatically get __init__() method
per
http://docs.sqlalchemy.org/en/rel_1_0/orm/extensions/declarative/api.html#sqlalchemy.ext.declarative.declarative_base.params.constructor
However when I declare class as
Base = declarative_base(metadata=metadata)

Thanks Mike.

be based upon. Is there any way to do such a copy and modification?
Is the answer above still the best way to get DDL resulting from calling
create_all()?

Hi!
Unfortunately it's impossible to insert empty string in not null column in
Oracle (http://stackoverflow.com/q/203493/95735).
That's why I would like to declare specific column as nullable only for
Oracle dialect.
How to do this?

As I've got no replies on SQLAlchemy-Continuum

would post here hoping someone knows this extension and could shed some
light on what might be the reason for the error. In the issue there's small
test case and traceback.
Thank you in advance.
