When using JDO without annotations, database sequences are normally defined in the ORM file. Following discussion on the forum I was told that ObjectDB supports sequences if specified in the JDO ... javax.jdo.datastore. Sequence ; import testcase.Thing; public class Testcase { public static void main

Support we are a bit lost, where do we find that list/ sequence of query plans ? hgzwicker Hans-Georg

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
