The Jakarta Persistence Query Language (JPQL; formerly Java Persistence Query Language) is a platform-independent object-oriented query language[1]: 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[1]: 17, §1.3 , but operate against JPA entity objects rather than directly with database tables.[1]: 26, §2.2.3 

In addition to retrieving objects (SELECT queries), JPQL supports set based UPDATE and DELETE queries.
