Thanks for getting back to me and apologies for the stacktrace barf ;-)

One thing...I have the following line in my environment.py:

config['pylons.g'].sa_engine = engine_from_config(config, 'sqlalchemy.', convert_unicode=True, pool_size=1, max_overflow=3)

I can turn on/off the convert_unicode option and I still get the same error. I spoke with one of our DBAs and he said the results of roleseq.nextval is a number. SA is looking for a String here or None, according to the exception error:

exceptions.TypeError: expecting None or a string

Sooo...is this still an SA thing and if so what do you suggest as a workaround?

jon -

none of that has anything to do with the error message here. You need to grep thorugh your code for the specific string : Sequence(u'roleseq'), or something equivalent. I know its there because the Oracle dialect does not invent or reflect any sequence names. You need to make that sequence name into a regular string object; as above you'd take out the "u" inside the parenthesis.

let me know when you find it as I'd like to confirm this is the source of the issue....thanks !
