have you tried other example code in your environment ? Have you
tried examples from the documentation, running the SQLA unit tests,
trying a script that runs just "engine.execute("INSERT INTO
table ....""), trying a raw PyODBC script ? there's many ways to
narrow down precisely what point in the chain is causing a failure.
just running the failing program over and over again is not going to
get you very far if nothing is immediately apparent.
