How to write HQL Insert query?

Question

I am struggling to write a HQL query for inserting a new record in a table. I have seen some of insert query as below but I don't want insert data from another table as below code.

String hql = "INSERT INTO Employee(firstName, lastName, salary)"  + 
             "SELECT firstName, lastName, salary FROM old_employee";
Query query = session.createQuery(hql);
int result = query.executeUpdate();
System.out.println("Rows affected: " + result);

For example I have a table "User" with three fields like name, age, number and I have entity for this user table. what will be the insert query for this?

Answer 1

In HQL, only the INSERT INTO … SELECT … is supported; there is no INSERT INTO … VALUES. HQL only support insert from another table.

So query INSERT from SELECT is possible like this

Query query = session.createQuery("insert into Stock(stock_code, stock_name)" +
                "select stock_code, stock_name from backup_stock");
int result = query.executeUpdate();

If you have values and Entity just call

MyEntity e=new MyEntity();
e.setXXXX(the XXX values);
save(e);

HQL doesn't support such INSERT s so you have to do this by creating and persisting new entity.

You can read about it here .

Only the INSERT INTO ... SELECT ... form is supported. You cannot specify explicit values to insert.

Answer 3

You can do:

Foo foo = new Foo(any, columns, you, want);
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

session.save(foo); //Here you have the magic

session.getTransaction().commit();
session.close();

Just make sure you add all the values set as "not null", or you´ll get a nullException.
