Detailed Description

Query or command result set.

This behaves as a container (as defined by the C++ standard library) and provides random access const iterators to iterate over its tuples. A tuple can also be accessed by indexing a Result R by the tuple's zero-based number:

for (Result::size_type i=0; i < R.size(); ++i) Process(R[i]);
