Oracle Spatial Samples
Importing from an Oracle Spatial Database
Exporting to an Oracle Spatial Database
The following code sample illustrates exporting spatial data from a project drawing to an Oracle database.
Note The sample assumes an open project drawing
containing some objects. It also assumes that the connection object
is actually connected to a database. Click "Connecting to an Oracle
Database" for sample code.

#include "StdArx.h"
#include "AdMapOracleConnection.h"
#include "AdMapOracleExport.h"

// Declare export interface
AcMapOSEExport *pExport = new AcMapOSEExport(pConnection);
// Note: Before calling export functions, initialize the
// export interface to specify export options and which
// features to export
// Export Option 1 - Export only new objects and erase
// exported objects from the drawing
// Empty feature vector means export all features in the
// drawing database when you call export functions
