Why is my Spring Data JPA @Query Update Not Reflecting in the Database?

Spring Data JPA Update @Query not Updating?

In Spring Data JPA, the @Query annotation allows you to define custom JPQL or native SQL queries for modifying database rows. However, the @Modifying annotation alone may not trigger the necessary flushing and persistence operations to update the database.

To ensure changes are persisted to the database, it is recommended to use the clearAutomatically attribute within the @Modifying annotation. This attribute determines whether the persistence context is automatically cleared after the execution of the query. By setting clearAutomatically to true, changes made during the query execution are automatically detected and flushed to the database.

Here's an example of how you can use clearAutomatically in your @Modifying query:

@Modifying(clearAutomatically = true)
@Query("UPDATE Admin SET firstname = :firstname, lastname = :lastname, login = :login, superAdmin = :superAdmin, preferenceAdmin = :preferenceAdmin, address =  :address, zipCode = :zipCode, city = :city, country = :country, email = :email, profile = :profile, postLoginUrl = :postLoginUrl WHERE id = :id")
public void update(@Param("firstname") String firstname, @Param("lastname") String lastname, @Param("login") String login, @Param("superAdmin") boolean superAdmin, @Param("preferenceAdmin") boolean preferenceAdmin, @Param("address") String address, @Param("zipCode") String zipCode, @Param("city") String city, @Param("country") String country, @Param("email") String email, @Param("profile") String profile, @Param("postLoginUrl") String postLoginUrl, @Param("id") Long id);

By setting clearAutomatically to true, the persistence context is cleared after the execution of the update query. This forces the changes made to the Admin object to be persisted to the database.

Remember that clearAutomatically only affects the persistence context associated with the current EntityManager. If you are using multiple persistence contexts, you may need to manage flushing manually to ensure that changes are properly synchronized across all of them.
