What is HQL?

HQL, or Hibernate Query Language, is a query language used in conjunction with Hibernate, an object-relational mapping framework in Java. Using HQL, developers can retrieve and manipulate data from a database in an object-oriented way. HQL is similar to SQL (Structured Query Language), but instead of working with tables and columns in a relational database, HQL works with persistent objects in Java. By writing HQL queries, developers can easily perform various database operations such as selecting, inserting, updating, and deleting data. HQL allows developers to write portable queries that work regardless of the type of database being used. This makes it possible to easily change and change the database without having to change existing code. Like SQL, HQL can also be used to perform advanced queries and joins between different tables or objects. Compared to other query languages ​​for database management, HQL offers a simpler and more intuitive way to work with the database. Developers can take advantage of HQL's powerful features to create efficient and optimized database operations within their Java applications.Läs mer
