Re: [eclipselink-users] select part of an entity
|
Hey.. i know that with hibernate we can instrument da class for LazyLoad of properties.
Im using something like:
<target name="Instrument">
<taskdef name="instrument" classname="org.hibernate.tool.instrument.cglib.InstrumentTask">
<classpath refid="project.classpath" />
</taskdef>
<instrument verbose="false">
<fileset dir="target/classes">
<include name="**/Profissional.class" />
<include name="**/ProfissionalAssinatura.class" />
</fileset>
</instrument>
</target>
and in my entity i need to use:
@Basic( fetch = FetchType.LAZY )
public byte[] getBlAssinatura() {
return this.blAssinatura;
}
I wanna know if eclipseLink has something similar too ?

I have a table, which I run a very simple select on, for example,
select e from Email e where e.createDate between :start and :end
but the problem is that the Email has a column "body" which contains a lot of data, and I really don't need that information right now.... is there a way to make it not select that column?
the only solution I can think of is to create a new class with the fields I want from the Email entity, then do something like
select new itrac.data.EmailReport(e.id, e.name, e.subject, ...) from Email e where e.createDate between :start and :end
but is there a better way??
