{Test 2: Open the employee database and run a query}

{ This test opens the employee example databases with the supplied user name/password
  and runs a simple query with no parameters. Note that the password parameter
  is first supplied empty and then updated.

  Both the output metadata and the query plan are printed out, followed by the results of the query.

  A specific employee record is then queried, first using a positional parameter
  and then a parameter by name. In each case, the SQL Parameter metadata is also
  printed followed by the query results.

  Finally, the database is explicitly disconnected.
