Thanks for the quick answer. My question was
specifically about the PyMSSQL driver (not the PyODBC
driver).
The reason why I'm asking is that I would like to
connect from Linux.
PyODBC works fine on Windows. On Linux I simply don't
know what to use instead of...
driver=SQL+Server+Native+Client+11.0
...in the connection string when using a "Hostname-
based connection".
You use the ODBC connector that comes with FreeTDS in conjunction with
UnixODBC. That said, pymssql probably works a little better on linux so
you can set this autocommit flag using a connect hook (
http://docs.sqlalchemy.org/en/latest/core/events.html?highlight=connect#sqlalchemy.events.PoolEvents.connect)
or we can accept a PR for a real feature addition.
