Inhalt:

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. EJB QL or EJB-QL is a portable database query language for Enterprise Java Beans. It is used in Java EE applications. Compared to SQL, however, it is less complex but less powerful as well. The language has been inspired, especially EJB3-QL, by the native Hibernate Query Language HQL.EJB QL is a database query language similar like SQL. The used queries are somewhat different from relational SQL, as it uses a so-called "abstract schema" of the enterprise beans instead of the relational model. In other words, EJB QL queries do not use tables and their components, but enterprise beans, their persistent state, and their relationships.
