Jean-Baptiste,
I realized that in our own in-house "framework to simply to the max the
use of fetchPlan" (just like yours... and ours?) we must be doing the
same, so I refereshed my memories by looking back at that code for you
(written over a year ago) and suddenly remembered that indeed there is
> how to dynamically, using fetch plan, exclude (rather than adding) to
the fetch plan some attribute not to retrieve
I probably misunderstand, but doesn't FetchPlan.clearFields() +
FetchPlan.clearFetchGroups() followed by a few addField() do what you
want (I haven't tried) ?

Hi 周雁鸣,
CriteriaQuery cq = ...
TypedQuery tq = em.createQuery(cq);
tq.setFirstResult(0);
tq.setMaxResults(10);
List users = tq.getResultList();
long count = users.size();
This will, normally, generate TWO SQL queries - a SELECT {columns} ... and a
SELECT COUNT(id).
Ok?
