Abstract
The Java Persistence Query Language (JP QL) is the standard query language of JPA. It is a portable query language designed to combine the syntax and simple query semantics of SQL with the expressiveness of an object-oriented expression language. Queries written using this language can be portably compiled to SQL on all major database servers.
