You cannot have a VARCHAR column set to autoincrement = True. You should use an INTEGER column (for instance, most common) instead.

I have tried many things, but failed.

I guess one of the fields in your table is a text and you are trying to retrieve it as a number.

blaze-odo error when trying to export an odo result to csv with MSSQL backend

I'm having an issue exporting some data from a MSSQL back-end to csv using blaze and odo.
The first thing that I do is create a blaze.data object that connects to the MSSQL db using a dns connection and pyodbc as the driver.
adjustment_statuses is a table in the database that the blaze.data object is connected to.
Then I use odo to take that result set and output it to a csv. When I output to a json format it works as expected. My hunch is that there is some issue with mssql support as an odo backend. Any odo devs have any insight here?
ez = bz.data(EZ_DB)
result = ez.adjustment_statuses
odo(result, os.path.join(ETL_STAGING_LOC, 'ez_adjustment.csv'))

SQLAlchemy column with enum using PEP 435 compliant enum produces table creation error

I have an enum... defined very similarly to here.
When I try to create a table using the enum, as in the example, I get an error during table creation. It is a very vague error. Here is code that replicates the problem:
from sqlalchemy import Table, MetaData, Column, Enum, create_engine
import enum
class myEnum(enum.Enum):
one = 'one'
two = 'two'
three = 'three'
def main():
e = create_engine('sqlite:///:memory:')
e.echo = True
m = MetaData(bind = e)
t = Table('table', m, Column('my_enum', Enum(myEnum)))
t.create()
if __name__ == '__main__': main()
I get an AttributeError: replace when I run this code, with a seemingly useless stacktrace. I honestly don't even know where to begin debugging this and while I can conceive of a couple of possible workarounds, I am relatively new to SQLAlchemy so I'm not sure what the cleanest solution is. Surely basic enum support is a relatively simple expectation of a ORM framework?
Here is the full stack trace:

PEP-435 enum support is being added in 1.1.
1.1.0b1 was recently released. You can upgrade to 1.1.0b1 but be wary of bugs. Based on release history I would say the stable version should be released in a month or two.
how to upgrade:
pip install 'sqlalchemy==1.1.0b3'
