public class ReportQuery
Purpose: Query for information about a set of objects instead of the objects themselves. This supports select single attributes, nested attributes, aggregation functions and group bys.
Attribute Types:
retrievePrimaryKeys()
,
If the values are wanted in the result array then they must be added as attributes. For primary keys which are not mapped directly
you can add them as DatabaseFields (see above).
