JPA Criteria Tuple query fails with missing columns from join in group by clause (Spring Boot 2.7.8 and hibernate 5.6.14.Final)

I am trying to use the JPA Criteria API to filter the results and aggregate them using simple count, min, avg and max. I am using Spring Boot 2.7.8, so I am trying to use Interface-projections such that these aggregated results look the same as the simpler queries done automatically by the Spring repositories.
My domain entity (simplified for brevity) looks like this:
#Entity
#Table(name = "vehicle_stopped")
#IdClass(VehicleStopped.VehicleStoppedPK.class)
public class VehicleStopped implements Serializable {

#Column(name = "stopped_session_uuid", nullable = false)

pk.setStartTs(this.getStartTs());
pk.setStoppedSessionUuid(this.getStoppedSessionUuid());
return pk;
}

return endTs;
}
public void setEndTs(OffsetDateTime endTs) {
this.endTs = endTs;
}
public Double getDurationSeconds() {
return durationSeconds;
}
public void setDurationSeconds(Double durationSeconds) {
this.durationSeconds = durationSeconds;
}
public CameraZone getCameraZone() {

The code that I have in my Repository implementation looks like this:
public class SpecificationVehicleStoppedRepositoryImpl
implements SpecificationVehicleStoppedRepository {
#Autowired private EntityManager em;
#Autowired ProjectionFactory projectionFactory;
#Override
public List<VehicleStoppedAggregate> getStoppedVehiclesCount(Specification<VehicleStopped> spec) {
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<Tuple> query = builder.createTupleQuery();
Root<VehicleStopped> root = query.from(VehicleStopped.class);
Predicate predicate = spec.toPredicate(root, query, builder);
if (predicate != null) {
query.where(predicate);
}
Path<Number> duration = root.get("durationSeconds");
Path<CameraZone> zone = root.get("cameraZone");
query
.multiselect(zone,
builder.count(root).alias("totalVehicles"),
builder.min(duration).alias("minDuration"),
builder.avg(duration).alias("avgDuration"),
builder.max(duration).alias("maxDuration"))
.groupBy(zone);
List<Tuple> rawResultList = em.createQuery(query).getResultList();
return project(rawResultList, VehicleStoppedAggregate.class);
}
private <P> List<P> project(List<Tuple> results, Class<P> projectionClass) {
return results.stream()
.map(tuple -> {
Map<String, Object> mappedResult = new HashMap<>(tuple.getElements().size());
for (TupleElement<?> element : tuple.getElements()) {
String name = element.getAlias();
mappedResult.put(name, tuple.get(name));
}
return projectionFactory.createProjection(projectionClass, mappedResult);
})
.collect(Collectors.toList());
}
}
The interface-based projection I am trying to populate (using SpelAwareProxyProjectionFactory) is this:
public interface VehicleStoppedAggregate {
CameraZone getCameraZone();
Integer getTotalVehicles();
Double getMinDuration();
Double getAvgDuration();
Double getMaxDuration();
}
The call to getStoppedVehiclesCount() fails with the following error:
ERROR: column "camerazone1_.id" must appear in the GROUP BY clause or be used in an aggregate function
This error is coming from the PostgreSQL database, and rightly so because the SQL hibernate generates is incorrect:
select
vehiclesto0_.zone_id as col_0_0_,
count(*) as col_1_0_,
min(vehiclesto0_.duration_seconds) as col_2_0_,
avg(vehiclesto0_.duration_seconds) as col_3_0_,
max(vehiclesto0_.duration_seconds) as col_4_0_,
camerazone1_.id as id1_2_,
camerazone1_.name as name2_2_,
camerazone1_.type as type3_2_,
camerazone1_.uuid as uuid4_2_
from
vehicle_stopped vehiclesto0_
inner join
camera_zone camerazone1_
on vehiclesto0_.zone_id=camerazone1_.id cross
where
vehiclesto0_.start_ts>=?
and vehiclesto0_.start_ts<=?
and 1=1
and 1=1
and 1=1
group by
vehiclesto0_.zone_id
It is not grouping by the other fields it is requesting from the joined table.
If I had to use a normal class, instead of a Tuple, it would work, but it would mean I would have to create a class with a huge constructor for all fields for Hibernate to populate it.
Somehow, when I use Interface-based projections with Spring's repositories rather than my criteriaquery, the same scenario works. They manage to populate the one-to-many relationships just fine.
Is there a way to fix this and make Hibernate ask for the right fields?
I am using Hibernate 5.6.14.Final (as bundled with Spring Boot 2.7.8).

I believe the "solution" is two create two "independent" query roots and join them together:
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery<Tuple> query = builder.createTupleQuery();
Root<VehicleStopped> root = query.from(VehicleStopped.class);
// instead of Path<CameraZone> zone = root.get("cameraZone")
Root<CameraZone> zone = query.from(CameraZone.class);
query.where(builder.equal(zone, root.get("cameraZone")));
Path<Number> duration = root.get("durationSeconds");
query
.multiselect(zone,
builder.count(root).alias("totalVehicles"),
builder.min(duration).alias("minDuration"),
builder.avg(duration).alias("avgDuration"),
builder.max(duration).alias("maxDuration"))
.groupBy(zone);
session.createQuery(query).getResultList();
In that case Hibernate 5 produces following SQL (which actually looks weird from my perspective due to missing columns in group by clause):
select
naturalidc1_.id as col_0_0_,
count(*) as col_1_0_,
min(naturalidc0_.duration_seconds) as col_2_0_,
avg(naturalidc0_.duration_seconds) as col_3_0_,
max(naturalidc0_.duration_seconds) as col_4_0_,
naturalidc1_.id as id1_0_,
naturalidc1_.name as name2_0_,
naturalidc1_.type as type3_0_,
naturalidc1_.uuid as uuid4_0_
from
vehicle_stopped naturalidc0_ cross
join
camera_zone naturalidc1_
where
naturalidc1_.id=naturalidc0_.zone_id
group by
naturalidc1_.id
FYI. Your initial query does work in Hibernate 6 and produced SQL does look more correct but still weird:
select
c1_0.id,
c1_0.name,
c1_0.type,
c1_0.uuid,
count(*),
min(v1_0.duration_seconds),
avg(v1_0.duration_seconds),
max(v1_0.duration_seconds)
from
vehicle_stopped v1_0
join
camera_zone c1_0
on c1_0.id=v1_0.zone_id
group by
1,
2,
3,
4

wrong query generate by hibernate

I am new to hibernate and Data JPA. I try to do an insert into my table but the hibernate query has some columns in it that not exist in my table so it will throw an error. Actually at first when I run my code the hibernate add these extra columns to my table and then I change spring.jpa.hibernate.ddl-auto value to none in application.properties, but now when I delete those extra columns from my table and try to insert a new record I see those columns are in insert method.

I don't have content_id, creation_date, comment_count and dtype fields in my table and i don't know why hibernate add them into the query.
is there any way to change the query that hibernate created or fix this problem in any other way, how can I control or manage queries create by hibernate???
I also should mention that I use the postman to send data and check my code.

After lots of searching and working, I found that hibernate naming convention for table columns is in a way that it separate words by an underscore and that was the reason that I saw those columns inside the query generated by hibernate. So if you have a variable inside your class like creationDate hibernate try to converted to creation_date so when I change all my column's name in this method problem solved. Also, the dtype column is a special kind of column that will create by hibernate when many classes use the same table to insert data, it is because to distinguish which class insert the record inside the table and hibernate provide its value with the name of that class.

But you do have content_id and creation_date in your Content entity which the Question entity extends from

Hibernate can insert but does not delete entry

I am able to insert a new Entry of ExitTicket correctly (using ExitTicketService.java), with this function:

However when I try to delete an entry from the database table, the hibernate delete only does 'select' commands and never gets to do a 'delete'

please let me know if anything wrong done by me please help... Thank you

Identity sequencing uses special IDENTITY columns in the database to allow the database to automatically assign an id to the object when its row is inserted. Identity columns are supported in many databases, such as MySQL, DB2, SQL Server, Sybase and Postgres. Oracle does not support IDENTITY columns but they can be simulated through using sequence objects and triggers.
If you are using Oracle, that might be the reason.
You can change this code
#GeneratedValue(strategy = GenerationType.IDENTITY)
To this
#GeneratedValue(strategy = GenerationType.SEQUENCE)

PhysicianJpaController() might not find a physician with "physicianId",so you might be trying to do this:
builder.setPhysician(null);
while you have also this:
physician int(11) NOT NULL

hey guys thank you so much for your help issue that I found is in my entity as I check I found that condition is reserved keyword in mysql and because of this I got this error

Caused by: org.hibernate.QueryException: could not resolve property from inner enum class

Having this domain class and using hibernate 3.2.6 integrated with JPA under spring 3.2.4
#Entity
public class PriorityDeviceKeyword {
public enum PriorityDeviceKey {
ALL ("ALL", "ALL DEVICES"),
IOS ("IOS", "IOS"),
ANDROID ("ANDROID","ANDROID");
private final String name;
private final String id;
private PriorityDeviceKey(String name, String id) {
this.name = name;
this.id = id;
}
public String getName() {
return name;
}
public String getId() {
return id;
}
}
#Id
private Long id;
#Column(name = "key")
private PriorityDeviceKey key;
#ManyToMany
#JoinTable(name = "t_priority_device_set", joinColumns = #JoinColumn(name = "priority_device__id", referencedColumnName = "id"))
private List<PriorityDevice> priorityDevices;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public PriorityDeviceKey getKey() {
return key;
}
public void setKey(PriorityDeviceKey key) {
this.key = key;
}
public List<PriorityDevice> getPriorityDevices() {
return priorityDevices;
}
public void setPriorityDevices(List<PriorityDevice> priorityDevices) {
this.priorityDevices = priorityDevices;
}
}
When executing this query that I have below method in my DAO class that I execute
#Override
#SuppressWarnings("unchecked")
public Set<PriorityDevices> findPriorityAreas(PriorityDevicesKey key) {
String jpql = "from PriorityDevices as pak where pak.key.name = :keyName";
Query query = entityManager.createQuery(jpql);
query.setParameter("keyName", key.getName());
List<PriorityDevices> priorityDevices = query.getResultList();
return new HashSet<PriorityDevices>(priorityDevices);
}
I get this Exception thrown by the application:
2015-01-14 13:14:50,936 ERROR [com.controller.errors.Error500Controller] - Application thrown an exception
java.lang.IllegalArgumentException: org.hibernate.QueryException: could not resolve property: name of: com.domain.PriorityDevicesKeyword [from com.domain.PriorityDevicesKeyword as

Think these changes may work for you:
#Column(name = "key")
#Enumerated(EnumType.STRING)
private PriorityAreaKey key;
and
String jpql = "from PriorityAreaKeyword as pak where pak.key = :keyName";
Query query = entityManager.createQuery(jpql);
query.setParameter("keyName", key);

Hibernate stores enums as an oridnal. Or, when the field is annotated with #Enumerated(EnumType.STRING), as a string with the short name of the Enum. When annotated valid names would be {ALL, IOS, ANDROID}. Either way there is only a single field, the properties of the enum itself are not stored, they are constant after all.
If you want to query for an enum value you have to to query for pak.key = :key and use key as the parameter. Hibernate will do the required translation to ordinal or string.
