The JPQL (Java Persistence Query Language) supports defining subqueries , which are nested queries that are embedded in other queries. Subqueries are currently not supported by ObjectDB, and as a workaround, you can use a sequence of two or more queries, where the results of one query serves as a parameter in the next queries. support Support

Subqueries (nested queries) have been added to JDOQL (JDO Query Language) in JDO 2.1. This is the main feature of JDO 2.0-2.1-2.2 that is not implemented yet in ObjectDB 2. support Support

HUBERT Subqueries are currently not supported. The workaround in this case (which could also provide much better performance than subqueries ) is to maintain a reference to the last label directly in every RO object. support Support
