I have a fairly comparable setup, with SQLALchemy 0.5.3, Python 2.6,
FreeTDS 0.82, pyodbc 2.1.5, all running on Mac 10.5. Connecting to
SQL Server 2005 running on a virtual machine.
I've been using the connection string: "mssql://user:password@/?
dsn=schematest?driver=FreeTDS"
I can do simple connections using both pyodbc and sqlalchemy. I can
execute a query, though I don't have any data yet so they only return
empty results.
Trying to create tables tends to cause the following error though:
ProgrammingError: (ProgrammingError) Attempt to use a closed cursor.
None None
Running your test causes the same error, shown below. I'm a bit stuck
on what to try next, but I'll keep fiddling and let you know of
anything that works for me.
