Some database rows will be updated, and most DBMS do that in-place.
This is actually incorrect. There are almost no databases that actually do that anymore. All modern (decent) databases will create a new row when performing an update, and then mark the old row as deleted internally. This is significantly safer, performs better, and allows you to support other important transactional features.
