> Iterated queries can handle only basic results like single entity,
> {{Object[]}} and {{DataRow}}
> everything else is missing in the processing.
> This affects ColumnQuery most as it can return many more variants.
> What variants are broken:
> * all selects: joint prefetches
> * column query: several entities or entity + some other fields
> * column query: embeddables
> * column query: map function (see CAY-2812)
> * maybe something else (?)
