Spring Data JPA delete native query throwing exception

A method annotated with @Query executes a query in order to read from the database. Not to update the database. To do that, as the documentation indicated, you need to add the @Modifying annotation to the method:

All the sections above describe how to declare queries to access a given entity or collection of entities. Of course you can add custom modifying behaviour by using facilities described in Section 1.3, “Custom implementations for Spring Data repositories”. As this approach is feasible for comprehensive custom functionality, you can achieve the execution of modifying queries that actually only need parameter binding by annotating the query method with @Modifying:

Example 2.13. Declaring manipulating queries

@Modifying
@Query("update User u set u.firstname = ?1 where u.lastname = ?2")
int setFixedFirstnameFor(String firstname, String lastname);

This will trigger the query annotated to the method as updating query instead of a selecting one.

use this two annotations

import org.springframework.data.jpa.repository.Modifying;
import org.springframework.transaction.annotation.Transactional;

@Modifying
@Transactional
