Yes, if you do both within the same transaction. See http://en.wikipedia.org/wiki/Database_transaction > In other words do the writes to disk get serialized? I'm not sure if I understand this question, but yes, they are serialized. > And does transaction concurrency mode have an effect on this? Usually not, except if you disable locking.
