Using https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods.details as a reference, I see how I can write a method in a repository without using the @Query annotation, i.e.
List<User> findByEmailAddressAndLastname(String emailAddress, String lastname);
However, is there a similar way to write an update query through a naming convention?
i.e.
void updateAllFirstNameByLastNameEqualTo(String lastname)
Spring Data JPA Update Method seems to suggest that there isn't.
