Detailed Description

ResultAgg is a concrete sub-class of TDbiResultSet.

Concept ResultAgg is a concrete sub-class of TDbiResultSet that represents a single database query for either:-

1) A specific context with aggregated data (i.e. rows with AggNo != -1)

or:-

2) Any extended context query, even if that only produces a single row of unaggregated data.

The table is indexed using the index returned by TDbiTableRow::GetIndex which can be overridden by concrete subclasses.

Purpose To present the user with a single logical table even though the component parts may held in multiple TDbiResultSets and be loaded by separate I/O operations.

std::vector<const TDbiResultSet*> TDbiResultSetAgg::fResults [private]

Array of TDbiResultSets (vector<TDbiResultSet*>). The array index is NOT the aggregate number; it simply matches the rows are supplied by the TDbiValidityRecBuilder with first row of TDbiValidityRecBuilder excluded i.e. row n of builder creates a TDbiResultSet pointed to by fResults[n-1];
