The missing exception is a bug but requiring a commit() is correct
behaviour.  The DB-API specification says that in the documentation
for the Connection.commit() method:

        Commit any pending transaction to the database. Note that if
        the database supports an auto-commit feature, this must be
        initially off.

You can have the ISQL like behaviour by doing this:

db = Sybase.connect('SYBASE', user = 'sa', passwd = '', auto_commit = 1)
