Query Native - could not extract ResultSet - postgresql

Question

i have a problem.I explain my situation: SpringBoot + Hibernate + Multitenant (DB master + DB for tenant) + Postgressql. I have two datasource configurations, one for the master and one for each client's database. I need doing a query native in JPARepository And that's the only way I can do it
In my JPARepository :
public interface IEntity extends JpaRepository<Entity, Integer> {
........
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying ///Add 1
#Transactional ///Add 2
void restarID();
}
when I first call the method, I got:
> Hibernate:
ALTER SEQUENCE entity_identity_seq RESTART
> 2019-09-10 15:41:53.919 WARN 18680 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 02000
> 2019-09-10 15:41:53.919 ERROR 18680 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper : La consulta no retornó ningún resultado.
> 2019-09-10 15:41:53.940 ERROR 18680 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: could not extract ResultSet; nested exception is org.hibernate.exception.GenericJDBCException: could not extract ResultSet] with root cause
org.postgresql.util.PSQLException: La consulta no retornó ningún resultado.
After looking for solutions and discovered that he needed to add
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying
void restarID();
But the query is not made in hibernate and this error comes up:
> 2019-09-10 15:46:57.972 ERROR 14392 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query] with root cause
javax.persistence.TransactionRequiredException: Executing an update/delete query
I keep searching and find that I should add #Transactional. Then :
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying
#Transactional
void restarID();
But, then come back, I call the method, I got:
> Hibernate:
ALTER SEQUENCE entity_identity_seq RESTART
> 2019-09-10 15:41:53.919 WARN 18680 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 02000

Please, will anyone have any recommendations?
I am new to hibernate. Thank you.

If someone yet have the same problem, I've resolved it, adding the next to the query:
#Modifying(clearAutomatically = true)
#Transactional
