Following is the simple syntax of using ORDER BY clause: This clause lets Hibernate pull information from the database and group it based on a value of an attribute and, typically, use the result to include an aggregate value.
Following is the simple syntax of using GROUP BY clause: Hibernate supports named parameters in its HQL queries.
For example, the following statements delete a product whose identifier equals to 37: This way is simple and straightforward, because we don’t have to load a persistent instance from the datastore before deleting it.
