Enumeration Type Documentation

enum _V_enum

This enum describes different view properties. Depending on this type, the view behaves differently.

• V_hole: This view looks through to a table. It is possible to change the table contents through the view.
• V_window: This view looks through to a table. It is impossible to change the table contents through the view.
• V_transparent: This view does not change the underlying table. It can be expanded, but changes are not committed to the table
• V_frozen: This view is a constant view to a table. It does not change and cannot be changed.
• V_materialized: The view is the result of a select, and there is not an underlying table
• V_independent: The view is just a temporary collection of rows and columns w/o a table.

Function Documentation

template<class _TC >

std::ostream& print_it	(	std::ostream &	o,
		const _TC &	t
	)			[inline]

This internal function is called from operator<< for columns. This hack was necessary, because a direct call of the operator<< for the class _TC did not work properly with g++ 3.2.
