No, you misunderstand.  nextset() is used when you issue several SELECT
statements in a single request.  The first fetchall() gets the results of
the first SELECT statement.  To get the next one, you use nextset().

Your example only had one SELECT:

If you are only issuing one SELECT, like most applications, then nextset()
serves no purpose.  If you did something like this:

  sql = "select * from wjtmp; select count(*) from wjtmp;"

That's when you need nextset().  Personally, I've never used it.
