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
