i have a table like this one:

id | name | score

mapped to a POJO via XML with Hibernate. The score column i only need in oder by - clauses in HQL. The value for the score column is calculated by an algorithm and updated every 24 hours via SQL batch process (JDBC). So i dont wanna pollute my POJO with properties i dont need at runtime.

For a single column that may be not a problem, but i have several different score columns. Is there a way to map a property for HQL use only?

For example like this:

<property name="score" type="double" ignore="true"/>

so that i still can do this:

from Pojo p order by p.score

but my POJO implementation can look like this:

public class Pojo
{
  private long id;

  private String name;

  // ... 
}

No Setter for score provided or property added to implementation.

using the latest Hibernate version for Java.
