// Revision 1.3  2001/06/05 18:40:20  cholm
// Removed BrDbInc.h an all references to it
//
// Revision 1.2  2001/03/22 20:44:18  cholm
// Added protection for NULL TSqlRow in SingleInstance methods, and cleaned
// up a bit of the stuff.
//
// Revision 1.1  2001/01/19 16:30:48  cholm
// Revisited the Run database classes. Deleted old implemtation via BrRun,
