title: why do we have to use @Modifying annotation for queries in Data Jpa
body: <p>for example I have a method in my CRUD interface which deletes a user from the database:</p>
  
  <pre><code>public interface CrudUserRepository extends JpaRepository&lt;User, Integer&gt; {
  
      @Transactional
      @Modifying
      @Query("DELETE FROM User u WHERE u.id=:id")
      int delete(@Param("id") int id, @Param("userId") int userId);
  }
  </code></pre>
  
  <p>This method will work only with the annotation @Modifying. But what is the need for the annotation here? Why cant spring analyze the query and understand that it is a modifying query?</p>
