Subject [jira] Reopened: (OPENJPA-1277) Support JPQL to Criteria Query conversion
Date Thu, 30 Sep 2010 17:20:32 GMT

Pinaki Poddar reopened OPENJPA-1277:
------------------------------------


Nothing is done on this issue and was closed by oversight/mistake.

The issue as it currently stands has no resolution.
The implementation artifacts are available at runtime to achieve this goal.

But what is unclear is the usage point of view for such a feature. It appears that such a
feature should provide support more at design-time rather than at runtime. However the current
JPA programming model is entirely based on runtime artifacts and has absolutely no design-time
utility API. Unless that larger issue is addressed, it is not advisable to approach this specific
problem in isolation.

> Develop a mechanics to generate a Criteria Query from a JPQL string.
> A mechanics to convert an existing JPQL string into a Criteria  Query will ease adoption
of the new API. 
> The conversion mechanics should operate both a design-time (to emit Java source code)
as well as runtime (to instantiate of Criteria  Query instances).
