Detailed Description

Reference to one row in a result.

A tuple represents one row (also called a tuple) in a query result set. It also acts as a container mapping column numbers or names to field values (see below):

cout << tuple["date"].c_str() << ": " << tuple["name"].c_str() << endl;

The tuple itself acts like a (non-modifyable) container, complete with its own const_iterator and, if your compiler supports them, const_reverse_iterator.
