Logical operators in JPQL and JPA criteria queries combine simple Boolean expressions to form complex expressions. Logical operators ObjectDB supports two sets of logical operators, as shown in the following table: Set 1: JPQL / SQL Set 2 : Java / JDO AND && OR || NOT ! JPQL uses SQL notation

It groups the API types into logical sections to help you locate core concepts, query facilities, metamodel details, configuration options, annotations, and exception information

As explained in Chapter 2 , you can delete entities from the database by following these steps: Retrieve the entities into an EntityManager . Remove these objects from the EntityManager within an active transaction, either explicitly by calling the remove method or implicitly through a cascading

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

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

You can update existing entities, as explained in chapter 2 , by following these steps: Retrieve the entities into an EntityManager . Update the relevant entity fields within an active transaction. Apply the changes to the database by calling the commit method. JPQL UPDATE queries provide
