Ignore parameter markers in SQL if no parameters are passed to cursor.execute

[craigahobbs]

1. Execute the following script:

import ctds

connection = ctds.connect('localhost', user='sa', password='password')
with connection:
    with connection.cursor() as cursor:
        cursor.execute('''\
/* this is great code: */
select @@version
''')
        row = cursor.fetchone()
        print(row[0])

Expected: Success - prints db version Actual: "_tds.InterfaceError: invalid parameter marker" - caused by ':' in multi-line comment
