如何使用Spring Data编写OrientDB更新查询

Question

I have repository and update method:

public interface TestRepo extends OrientObjectRepository<Test>
{
    @Query("UPDATE Test t SET t.a = :a WHERE t.b = :b")
    void updateTest(
            @Param("b") String b, @Param("a") int a);
}

If I run this update method and I get IllegalArgumentException . Most likely my query is incorrect for OrientDb. So is there any tutorial how to write update query with Spring Data?

Answer 1

You could try to change your query in this way (by removing the t variable):

UPDATE Test SET a = :a WHERE b = :b

EDITED

you can try to add @Modifying(clearAutomatically = true) in this way:

@Modifying(clearAutomatically = true)
@Query("UPDATE Test t SET t.a = :a WHERE t.b = :b")
void updateTest(
        @Param("b") String b, @Param("a") int a);

Hope it helps
