35 | Collections in JPQL and Criteria QueriesCollections may appear in JPQL queries: as parameters - when collections are assigned as arguments ... , which should be used for checking other collections, such as a collection that is passed to the query ... of collection, so in ObjectDB these operators are treated as synonyms.

35 | Numbers in JPQL and Criteria QueriesNumeric values may appear in JPQL queries in many forms: as numeric literals - e.g. 123, -12.5. as ... of any type and always returns a double value. Criteria Query Arithmetic Expressions JPQL arithmetic operators and functions (which are described above) are available also as JPA criteria query |
34 | Criteria Query ExpressionsThe following interfaces are in use in representing general expressions in criteria queries: See the Query Expressions section for more details and examples. |
34 | JPA Annotations for SQL QueriesThe following JPA annotations are designated for SQL queries on relational databases: ObjectDB supports only the preferred JPA query language, JPQL, and silently ignores all the above annotations. |
31 | createNamedQuery(name, resultClass)> resultClass ) Create an instance of TypedQuery for executing a Java Persistence query language named query ... specified by the resultClass argument. Parameters: name - the name of a query defined in metadata ... : IllegalArgumentException - if a query has not been defined with the given name or if the query string is found |
