  <para>
   When sending more than one SQL statement to the server or
   executing a stored procedure with multiple results, it will cause
   the server to return multiple result sets. This function will
   test for additional results available form the server. If an
   additional result set exists it will free the existing result set
   and prepare to fetch the rows from the new result set.
