Subject Re: Direct mapping between Named query and Pojo
Date Wed, 03 Mar 2010 15:42:20 GMT
There are two options:

1. EJBQL. This supports "compound" results, with each result object  
being an Object[], with each array element corresponding to a separate  
entity or a scalar.
2. DataRows (mentioned already in this thread). Then each row is a map  
that can contain arbitrary data.
