JPQL (Jakarta Persistence Query Language, formerly Java Persistence Query Language) is a platform-independent object-oriented query language defined as part of the Jakarta Persistence API (JPA) specification. JPQL is used to perform database operations against entities stored in a relational database. Instead of operating directly on database tables, JPQL operates on entities and their persistent fields or properties. This abstracts the database schema from the application code, making applications more portable and maintainable. JPQL queries are typically used for selecting, updating, and deleting data within the persistence context.
