Description

This provider is used to create virtual connections which "incorporate" tables from other connections. This is typically used when one need to compare or migrate data from one database to the other by creating two connections for each database, and "binding" them into a third virtual connection using this provider.

Using gda_virtual_connection_open() with this provider as argument will generate a GdaVconnectionHub connection object, from which connections can be added.
