How to update records that are dependent on a different table using JPA Criteria API? - postgresql

Question

I have the following entities with the one-to-one relationship:
#NoArgsConstructor
#Data
#DynamicUpdate
#Table(name = "product")
#Entity
public class Product implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.UUID)
#Column(name = "id", updatable = false, nullable = false)
private UUID id;
#Column(name = "feed", length = 100, nullable = false)
private String feed;
// Omitted columns
#ToString.Exclude
#OneToOne(mappedBy = "product", cascade = CascadeType.ALL)
private PushPermission pushPermission;
}
#Data
#NoArgsConstructor
#Table(name = "push_permission")
#Entity
public class PushPermission implements Serializable {
#Id
#Column(name = "id", updatable = false, nullable = false)
private UUID id;
// Omitted columns
#ToString.Exclude
#OneToOne
#JoinColumn(name = "id")
#MapsId
private Product product;
}
I would like to update all records in PushPermission where feed (column from Product) is not equal to PROMO using JPA Criteria API.
I have used the following CriteriaUpdate:
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaUpdate<PushPermission> criteriaUpdate = cb.createCriteriaUpdate(PushPermission.class);
Root<PushPermission> root = criteriaUpdate.from(PushPermission.class);
criteriaUpdate.set("exampleField", true);
Predicate selectedProductsPredicate = root.get("id").in(ids);
Predicate skipFeedPredicate = cb.notEqual(root.get("product").get("feed"), "PROMO");
criteriaUpdate.where(cb.and(selectedProductsPredicate, skipFeedPredicate));
Query query = entityManager.createQuery(criteriaUpdate);
query.executeUpdate();
but I got the following error message:
ERROR: missing FROM-clause entry for table "p2_0"
Generated update statement by Hibernate:
update
push_permission
set
exampleField=?,
where
id in(?,?)
and p2_0.feed!=?
Besides I tried to use joining:
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaUpdate<PushPermission> criteriaUpdate = cb.createCriteriaUpdate(PushPermission.class);
Root<PushPermission> root = criteriaUpdate.from(PushPermission.class);
Join<PushPermission, Product> productJoin = root.join("product");
criteriaUpdate.set("exampleField", true);
Predicate selectedProductsPredicate = root.get("id").in(ids);
Predicate skipFeedPredicate = cb.notEqual(productJoin.get("feed"), "PROMO");
criteriaUpdate.where(cb.and(selectedProductsPredicate, skipFeedPredicate));
Query query = entityManager.createQuery(criteriaUpdate);
query.executeUpdate();
but I got the following message:
The root node [me.foo.app.PushPermission] does not allow join/fetch
Hibernate didn't generate any update statement.
I use Postgres SQL 14.5 and I know I can do the native query which works:
update push_permission set exampleField=true from product where push_permission.id=product.id and product.feed<>'PROMO';
but I wonder I can do it with the use of JPA Criteria API.
I use Spring Boot 3.0.2 that implies Hibernate 6.

That's not yet possible, but support for that is on the roadmap. For now, you'd have to use an exists subquery to model this i.e.
update PushPermission p
set p.exampleField=true
where exists (
select 1
from product pr
where p.id=pr.id
and pr.feed<>'PROMO';
)
