To add two expressions with logical operations:įinal Session session = HibernateUtil.getHibernateSession() įinal SessionFactory sessionFactory = HibernateUtil.getHibernateSessionFactory() ĬriteriaDefinition query = new CriteriaDefinition(sessionFactory, Item. Predicates = cb.like(root.get('itemName'), 'chair%') Well be working with Hibernate 4.3.5.Final (and applicable updates for Hibernate 5.0 ), and using Hibernate as a JPA Provider for the most part of. Predicates = cb.isNull(root.get('itemDescription')) If you’re a Java programmer who wants to learn the fundamentals and some of the advanced topics of Java Persistence with Hibernate, then you’re the one this course is designed for. So, taking your example, when executing this JPQL query: FROM Employee emp JOIN emp. T he Criteria API allows us to easily chain expressions: Predicate predicates = new Predicate Hibernate ORM Hibernate Search Hibernate Validator Hibernate Reactive Hibernate Tools Other projects. When using JOIN against an entity associations, JPA will generate a JOIN between the parent entity and the child entity tables in the generated SQL statement. We can also use the methods isEmpty() and isNotEmpty() to test if a List within a class is empty or not.Īdditionally, we can combine two or more of the above comparisons. To check if the given property is not null: cr.select(root).where(cb.isNotNull(root.get('itemDescription'))) To check if the given property is null: cr.select(root).where(cb.isNull(root.get('itemDescription'))) Items having itemName in Skate Board, Paint and Glue: cr.select(root).where(root.get('itemName').in('Skate Board', 'Paint', 'Glue')) Records having itemPrice between 100 and 200: cr.select(root).where(cb.between(root.get('itemPrice'), 100, 200)) Items having itemName contain Chair: cr.select(root).where(cb.like(root.get('itemName'), '%chair%'))
