Jakarta Persistence (JPA) represents queries with two interfaces: the Query interface, which was the only query interface in JPA 1 , and the TypedQuery interface, which was introduced in JPA 2. The TypedQuery interface extends the Query interface. Use the Query interface primarily when the query

: Employee employee = em. find (Employee.class, 1 ); em. getTransaction (). begin (); em. remove (employee

Most JPQL queries use at least one comparison operator in their WHERE clause. Comparison operators ObjectDB supports two sets of comparison operators, as shown in the following table: Set 1 : JPQL/SQL Set 2: Java/JDO Less Than Less Than or Equal To = Equal To = == Not Equal To != The main

This tutorial demonstrates how to create and run a full Java EE 6 MVC (Model View Controller) web application using GlassFish, ObjectDB and JPA. Since this web application uses Java EE 6 EJB (session beans) it requires a full Java EE 6 application server, such as GlassFish 3.0. 1 or JBoss AS 6
