How to write Joins using CriteriaUpdate?

I would like to request please help me to find out solution for updating the foreign key value in other table.
for example:-
If we taken Device Table
columns are :- devicename
deviceId
displayname
userId
roomId
isDeleted
other table is Rooms Table
columns are :- roomName
roomId
roomType
isDeleted
Hear it is looking like one-to-many relationship.
i.e., one room will contain many devices.
In the above two tables roomId is primary key in Rooms Table and roomId is forgin key in Device Table.
So, Hear what we want is we have to update the roomId in DeviceTable.
I tried but, I cant able to find the solution for this, I request you guys' please help me for this solution.
the database tables will be like
Room Table(room_table)
room_id room_name room_type
1 ROOM1 ROOM_TYPE1
2 ROOM2 ROOM_TYPE2
Device Table like(device_table)
device_id device_name display_name room_id
1 DEVICE1 DISPLAY1 1
2 DEVICE2 DISPLAY2 2
I hope you guys understand the above tables.
So, now Coming to my required task is:-
I want to update roomId in device table i.e., for DEVICE2 we have to update from roomId 1 to roomId 2 AS SHOWN IN BELOW.
Device Table like(device_table)
device_id device_name display_name room_id
1 DEVICE1 DISPLAY1 1
2 DEVICE2 DISPLAY2 2
for this I wrote java code like:-
#Entity
#Table(name = "device_table")
public class Device {
#Id
#Column(name = "device_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int deviceId;
#Column(name = "device_name")
private String deviceName;
#Column(name = "display_name")
private String dispalyName;
#ManyToOne(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
//private List<Room> roomList = new ArrayList<>();
#JoinColumn(name = "ROOM_ID")
private Room roomList;
//setters & getters
}
#Entity
#Table(name = "room_table")
public class Room {
#Id
#Column(name = "room_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int roomId;
#Column(name = "room_name")
private String roomName;
#Column(name = "room_type")
private String roomType;
#OneToMany(mappedBy="roomList")
private Collection<Device> deviceList = new ArrayList<>();
//setters & getters
}
For updating I tried code like below.
public class SaveDataClientTest {
public static void main(String[] args) {
try (Session session = HibernateUtil.getSessionFactory().openSession()) {
session.beginTransaction();
CriteriaBuilder userBuilder = session.getCriteriaBuilder();
CriteriaUpdate<Device> deviceUpdate = userBuilder.createCriteriaUpdate(Device.class);
Root<Device> deviceUpdateRoot = deviceUpdate.from(Device.class);
Subquery<Device> deviceSubquery = deviceUpdate.subquery(Device.class);
Root<Device> roomRoot = deviceSubquery.from(Device.class);
Join<Device, Room> join = roomRoot.join("roomList", JoinType.LEFT);
deviceUpdate.set(deviceUpdateRoot.get("dispalyName"), "DISPLAY12345");
deviceUpdate.set(join.get("roomId"), 2);
deviceUpdate.where(userBuilder.equal(deviceUpdateRoot.get("deviceName"), "DEVICE2"));
int returnValue = session.createQuery(deviceUpdate).executeUpdate();
System.out.println(returnValue);
session.getTransaction().commit();
} catch (HibernateException e) {
e.printStackTrace();
}
}
}

will you please help me to solve this issue.
Thanks.

Have you tried the following?
CriteriaUpdate<Device> deviceUpdate = userBuilder.createCriteriaUpdate(Device.class);
Root<Device> deviceUpdateRoot = deviceUpdate.from(Device.class);
deviceUpdate.set(deviceUpdateRoot.get("dispalyName"), "DISPLAY12345");
deviceUpdate.set(deviceUpdateRoot.get("roomList").get("roomId"), 2);
deviceUpdate.where(userBuilder.equal(deviceUpdateRoot.get("deviceName"), "DEVICE2"));
int returnValue = session.createQuery(deviceUpdate).executeUpdate();
or this?
CriteriaUpdate<Device> deviceUpdate = userBuilder.createCriteriaUpdate(Device.class);
Root<Device> deviceUpdateRoot = deviceUpdate.from(Device.class);
deviceUpdate.set(deviceUpdateRoot.get("dispalyName"), "DISPLAY12345");
deviceUpdate.set(deviceUpdateRoot.get("roomList"), session.getReference(Room.class, 2));
deviceUpdate.where(userBuilder.equal(deviceUpdateRoot.get("deviceName"), "DEVICE2"));
int returnValue = session.createQuery(deviceUpdate).executeUpdate();

How to get dependent objects

I'm trying to get the accounts existing in a bank, but the list is empty even though the link between the two exist in the database.
Knowing that the interaction between the database and my program works fine, except that bank.getAccounts() returns an empty list.
here is my code.
What i'm trying to do is:
public class Main {
public static void main(String[] args) {
Bank bank = new Bank();
bank.setName("XXX");
bank.setStreet("XXX");
bank.setPc("XXX");
bank.save();
Account c = new account();
c.setBalance(10);
c.setBank(bank);
c.save();
account c2 = new account();
c2.setBalance(20);
c2.setBank(bank);
c2.save();
for(account c : bank.getAccounts())
System.out.println("account n°: " + c.getId() + ", balance: " + c.getBalance());
}
}
The Bank class is:
#Entity
#Table(name = "BANK")
public class Bank implements Serializable {
/**
*
*/
private static final long serialVersionUID = 8199961750065782869L;
static private BankDAO dao;
private long id;
private String name;
private String street;
private String pc;
private Set<Account> accounts;
public Bank() {
super();
this.accounts = new HashSet<>();
}
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getPc() {
return pc;
}
public void setPc(String pc) {
this.pc = pc;
}
#OneToMany(cascade = CascadeType.ALL, mappedBy="bank")
public Set<Account> getAccounts() {
return accounts;
}
public void setAccounts(Set<Account> accounts) {
this.accounts = accounts;
}
// Equals and hashCode implementations deleted
#Transient
private BankDAO getDao() {
if(Bank.dao == null)
dao = BankDAO.getDAO();
return Bank.dao;
}
public long save() {
Bank.dao = this.getDao();
return dao.save(this);
}
public int delete() {
Bank.dao = this.getDao();
return dao.delete(this);
}
}
The Accounts class code:
#Entity
#Table(name = "Account")
public class Account implements Serializable{
private static final long serialVersionUID = 7224745445343369682L;
static private AccountDAO dao;
public long id;
public int balance;
public Bank bank;
public Account() {
super();
}
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public int getBalance() {
return balance;
}
public void setBalance(int balance) {
this.balance = balance;
}
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="bank_id", nullable=false)
#Id
public Bank getBank() {
return bank;
}
public void setBank(Bank bank) {
this.bank = bank;
}
#Transient
private AccountDAO getDao() {
if(Account.dao == null)
dao = AccountDAO.getDAO();
return Account.dao;
}
/*
* save the state of the object: save or update
* #return: the id of the object
*/
public long save() {
Account.dao = this.getDao();
return dao.save(this);
}
public int delete() {
Account.dao = this.getDao();
return dao.delete(this);
}
}

It wont work that way as as you can see # checkpioint 1 you have you Bank object and nothing will change its state. I gues you would like to Bank->account poulate by checkpoint 2 and 3 but this is not going to happen.
What you have to do is to put that relations manually by simply
bank.getAccounts().add(c1);
However in order to relations to work like you would expect (as bank is already initialized so no lazy fetch will occure), you need to actually fetch your bank again via eg query. Then, newly returned bank will have unitialized collections proxies and will indeed perform additional select (if not eager fetch specified) to get collections of accounts associated with that bank.

I found the problem.
i was using find(id) method to fetch the bank from the database, when i use load(id) or get(id) it works fine.
Best regards.

Hibernate Table not found, MappingException and AssertionException

I tried to map an existing Postgresql Database with Hibernate and it already worked while I didn't add Inheritances per Subclass to Hibernate
This is the superclass
#Entity
#Table(name = "place", schema = "public", catalog = "dbp")
#Inheritance(strategy = InheritanceType.JOINED)
public class PlaceEntity {
private long id;
private String name;
private String url;
// private CityEntity cityById;
private ContinentEntity continentById;
private CountryEntity countryById;
And this is the subclass
#Entity
#Table(name = "city", schema = "public", catalog = "dbp")
#PrimaryKeyJoinColumn(name = "cityid", referencedColumnName = "id")
public class CityEntity extends PlaceEntity{ //WHEN I ADD extends PlaceEntity , THE ERROR OCCURES
private Long cityid;
private Long ispartof;
//private PlaceEntity placeByCityid;
private CountryEntity countryByIspartof;
private Collection<PersonEntity> peopleByCityid;
private Collection<UniversityEntity> universitiesByCityid;
Then Intellij throughs the following exception:

I already searched for related problems but couldn't find any solution.
I'd be very glad if anyone could help me :)
Always when i delete

it runs smoothly and it maps als Tables, place included.
I already invested several days in that problem ^^
Sorry for the strange english, it's not my foreign language :)
Nice evening fellows
Eisenbahnplatte

I have faced the same issue (or something very similiar).
Hibernate 5.2.17.Final + PostgreSQL + Inheritance.JOINED.
Solved it by removing "catalog" attribute from mapping. Try to replace
#Table(name = "place", schema = "public", catalog = "dbp")
with
#Table(name = "place", schema = "public")
Hope this helps.

Given the error:
Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, column 2122
SUB_TYPE
and character 2122 in the generated query is at SUB_TYPE in the generated query (around ..., empresas0_.SUB_TYPE as SUB60_0_, ...); and given that SUB_TYPE is a keyword (but not a reserved word) used to indicate the type of a blob (eg in create table or casts), my initial guess would be with:
#Column(name = "SUB_TYPE")
private Blob SUB_TYPE;
However a quick test - against a snapshot of Firebird 3 - shows that this is a valid column name. I currently don't have access to a released Firebird version (eg Firebird 2.5.3), so it is possible that some of the parser rules have been relaxed between Firebird 2.5 (or the version you are using) and Firebird 3. If that is the case, then forcing Hibernate to quote the object name might help (note the extra quotes):
#Column(name = "`SUB_TYPE`")
private Blob SUB_TYPE;

Exception in thread "main" org.hibernate.AnnotationException: #OneToOne or #ManyToOne

I want to do one-to-many mapping in hibernate,but it is showing exception,I tried a lot but unable to find solution
I have below two tables
dept
deptno -- number primary key
dname -- varchar2(10)
loc -- varchar2(10)
employee1
empno -- number primary key
username -- varchar2(10)
deptno -- number(10) foreign key
when I am not adding #Entity annotation on Dept.java class I am getting below stacktrace

can anyone help me to find the mistake...
below is the githib link
git#github.com:mcarajeev/hibernate3.git

In your Employee.java you have added deptno as a join column and you have already added deptno as column so it is creating two deptno in same table which is giving Exception.
Solution : You can remove private int deptno from Employee.java as your Join column will work as foreign key.

Looking at the entities, this exception should not be thrown, however when I checked code on git, #Entity annotation is missing on Dept class, are you sure that you are using #Entity?
Note that this exception is thrown when you map an entity about which hibernate is not aware off. Like in your case, Employee has association with Dept but Dept is not known to hibernate as an entity as you have not used #Entity.
private int deptno;
#ManyToOne
#JoinColumn(name = "deptno")
private Dept dept;
Remove private int deptno, hibernate will generate it as a part of association.
