{Test 4: Update, Insert and Delete Queries}

{ This test opens the employee example databases with the supplied user name/password
  and runs several queries:

  1. Update an employee record and report affected rows.

  2. Show Changed Record

  3. Insert new employee record and report affected rows Repeat with a duplicated
     parameter name.

  4. Show inserted record and then delete it and report affected rows

  5. Repeat insert with a null PHONE_EXT.

  6. Show inserted record and total records

  7. Prepare query again and report results

  8. Prepare query with a different transaction and report results.

  9. Open Cursor with a different transaction and report results.

  10. Implicit Rollback and disconnect.
