The Hibernate Query Language (HQL) and Java Persistence Query Language (JPQL) are both object model focused query languages similar in nature to SQL. HQL is a superset of JPQL. A HQL query is not always a valid JPQL query, but a JPQL query is always a valid HQL query.
Both HQL and JPQL are non-type-safe ways to perform query operations. Criteria queries offer a type-safe approach to querying.
