hmmmm. still i have no working example.

there is this python-sybase module and i cannot get it to work. there
must be something wrong here. Could you give me a query that runs on the
above configuration? i want to create the query dynamically. i.e. no
static query, but instead some query like the one above.

is the python-sybase module broken?
