// Purpose: Implementation of the wxDbTable class.
// Author: Doug Card
// Modified by: George Tasker
-// Mods: April 1999
-// -Dynamic cursor support - Only one predefined cursor, as many others as
-// you need may be created on demand
-// -Reduced number of active cursors significantly
-// -Query-Only wxDbTable objects
