Re: [eclipselink-users] select part of an entity

[Diego Coronel <diego.coronel@xxxxxxxxx>]

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??
