Well, I guess it depends on what it is you are trying to do.  If you are
trying to modify the database, this is not correct.  The dictionary you
get back from a query is a local copy -- a snapshot of the query
results.  The only way to make a change is to create an UPDATE query and
call cursor.execute to send it to the database server.

Why don't you post more of your code, along with a short description of
what you're trying to do, and we can tell you how to do that?
