[news.eclipse.rt.eclipselink] Re: Calculations of field values using oth

[james.sutherland@xxxxxxxxxx (James )]

You could change this to a query instead of a persistence attribute.

If you need to map it, you could use a TransformationMapping in 
EclipseLink, or use a postBuild event to query the data.  You could also 
just lazy initialize the field using a query.

Another solution would be define a database view that include the computed 
values and map your object to the view.
