  1. Nested/Sub Queries within EJB 2.0 (3 messages)

    Hi,
    is it possibly to perform Nested/Sub Queries within EJB 2 and if so any examples would be appreciated.

    Thanks
  2. Hi

    The message should have read -

    Is it possible to define Nested Queries, using EJB Query Lang
    within EJB 2.

    Thanks
  3. The current release of EJB spec does not support EJB QL subquery. However, it is listed as the future feature in the EJB 2.1 spec.

    EJB Spec 2.1 Proposed Final Draft 2:

    Appendix A: Features Deferred to Future Releases

    ? Further extensions to EJB QL, e.g.: subqueries, multi-valued results, dynamic queries
