function testUpdateAffectedRows() {

  // At 5am in the morning, all band members but those with a priority 1 task
  // are sleeping. So we set their tasks to 'sleep'. 5 records match the
  // condition and therefore are affected by the query, even though two of
  // them actually don't have to be changed because their value was already
  // 'sleep'. Still, execute() should return 5 affected rows, not only 3,
  // because that's cross-db expected behaviour.

  $this
    ->assertIdentical($num_rows, 5, 'Correctly returned 5 affected rows.');
