Hi there,

I have the following query in Oracle SQL:

Code:

SELECT COUNT(dv.pk_id),
  MIN(dv.date_time)      ,
  MAX(dv.date_time)      ,
  s.name                ,
  s.pk_id,
  dv.fk1_id
FROM data_values dv, sites s
WHERE dv.fk2_id = s.pk_id
  AND dv.date_time BETWEEN to_date('1900-01-01','YYYY-MM-DD') AND to_date('2009-07-31','YYYY-MM-DD')

GROUP BY s.site_name,s.pk_id,
  dv.fk1_id

Which is the procedure to create a mapping between this query and a new class?
Table sites is already mapped. The query above works fine and returns a List of basic objects with no getters of course.

Thanks in advance.
