I am struggling with Hibernate Criteria. My aim is to create the following request using Hibernate Criteria :
select
count(*) as y0_
from
PInterface this_
inner join
Product product2_
on this_.product_id=product2_.id
where
this_.product_interface_type_id=?
Here is my code:
@Entity @Table(name = "PInterface")
public class PInterface {
@Id
@GeneratedValue
@Column(name = "id", nullable = false, insertable = false, updatable = false)
private int id;
@Column(name = "product_id")
private int productId;
@Column(name = "product_interface_type_id")
private int type;
@ManyToOne(optional=false)
@JoinColumn(name = "product_id", referencedColumnName = "id", insertable=false, updatable=false)
private Product product;
}
@Entity @Table(name = "Product")
public class Product {
@Id
@GeneratedValue
@Column(name = "id", nullable = false, insertable = false, updatable = false)
private int id;
private String name;
}
//Criteria is :
Object criteria = sessionFactory.getCurrentSession()
.createCriteria(PInterface.class)
.add(Restrictions.eq("type", 1))
.setProjection(Projections.rowCount())
.uniqueResult()
;
However, the results ...
select
count(*) as y0_
from
PInterface this_
where
this_.product_interface_type_id=?
Where Inner join?
Thank you for help!
