>
> The goal is to create an abstract SelectDescriptor interface that would
> define what columns a select query contains and how to read them from result
> set. SelectDescriptor will support stacks of columns (needed in UNION queries
> with horizontal inheritance), it will also support complex Object[] results,
> mixing scalars and entities. This is a major refactoring effort that would
> tie together SELECT clause creating and coding of the DataRow keys (and
> hopefully will pave a way to future DataRow optimization/removal process).
