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
