Hibernate Query Language (HQL) is a powerful object-oriented query language used in Hibernate, an Object-Relational Mapping (ORM) framework for Java. HQL is designed to work with Hibernate's object model, allowing developers to perform database operations using object-oriented concepts rather than writing raw SQL queries.
HQL syntax closely resembles SQL, but it operates on persistent objects and their associated intermediaries. Instead of directly referring to database tables and columns, HQL uses the names of mapped Java classes and their properties. This makes it easier to work with complex object graphs and relationships.
