I have this query that updates some prices higher that 2 days ago, but does not work

  @Transactional
    @Modifying
    @Query("update HotelDailyPrice hdp  set hdp.price = (select avg (hp.price) "
            + "from HotelPrice hp where hp.id = ?1 and hp.updateDate > CURRENT_DATE - 2), hdp.day = ?2 ")
    void updateDailyAveragePrice (Hotel hotel, String dayDate);

Actually, JPA doesn't support time periods operations because not all databases support it. So you have following options:

  1. Calculate date programmatically (i.e. using calendar API or Java 8 Date Time API)
  2. Use native query
  3. Use concrete implementation if your JPA provider allows that. But AFAIK popular JPA providers don't give you such an option.
