Querying Using Criteria API in Hibernate 4.3

Hibernate provide Criteria Queries as an object-oriented alternative to HQL. Criteria Query is used to modify the objects and provide restriction for the objects. Many complex queries in HQL or even SQL may become larger over a period of time and spread over many lines; and will be difficult to update and maintain. We have already seen HQL in http://javajee.com/introduction-to-hibernate-query-language-hql-in-hibernate-43. [node:read-more:link]

Named Queries in HQL with hibernate 4.3

We can have queries saved with a name and later we can retrieve them simply using that name. We use @NamedQuery annotation to declare a named query. We can also have a named query for native sql. For native SQL we use the annotation @NamedNativeQuery annotation. This is one of the important advantages of having a named query: you can write native SQL. You can retrieve a Query object from a saved query name (hql and native named query) using session.getNamedQuery method. [node:read-more:link]
