In Sun's released J2EE6 there are introduced several improvings of JPQL,
analogue of our EJBQL [1]. Some features, like CASE expressions, look
exciting. Just curious, does anyone have a plan to improve EJBQL to supoort
that?

Andrus Adamchik: Yes, we probably should, as well as finishing EJB3.0 missing pieces like support for constructors and OUTER joins (IIRC these are the 2 things not working in Cayenne 3.0 EJBQL)... Also probably should rename it to CQL (Cayenne Query Language) to avoid wrong associations and allow us to add our own extensions (e.g. add support for DB expressions). Andrus
Aristedes Maniatis: If we are going to rename it, we should do it now, before the release and before people start relying on the naming we've just introduced with 3.0. But I think it is OK to leave it as EJBQL since it will help convince people moving from some other tool where they have created lots of queries they don't want to have to rewrite. A bit like HTML, it is mostly the same, most of the time. Except when it isn't because we do extra bits. Ari -- --------------------------> Aristedes Maniatis GPG
Andrus Adamchik: Too late to change anything in 3.0... As for EJBQL, the term may not be familiar to many users. I am actually a bit confused myself. All the JPA literature talks of JPQL, and only the spec talks of EJBQL. We picked the worst term of the 2 IMO :) Andrus
