The Jakarta Persistence Query Language (JPQL; formerly Java Persistence Query Language) is a platform-independent object-oriented query language: 284, §12 defined as part of the Jakarta Persistence (JPA; formerly Java Persistence API) specification. JPQL is used to make queries against entities stored in a relational database. It is heavily inspired by SQL, and its queries resemble SQL queries in syntax: 17, §1.3 , but operate against JPA entity objects rather than directly with database tables.: 26, §2.2.3 In addition to retrieving objects (SELECT queries), JPQL supports set based UPDATE and DELETE queries.
