    No. auto-increment keys means that the incrementation of the key is done automatically by the database. Sometimes (I'm looking at you, Oracle!) you need a sequence + trigger combination to do so, but you never need to look up the previously inserted value for the key, add 1, then use it.

  • With some persistence frameworks such as JPA if you want to return the value of the key ithat was created back to the caller you need to load up the record in order to see the key. Commented May 8, 2017 at 14:03
