Installing a DBTools error handler

 Insert this function into your application.  Activate the error handler by placing a call in main() to RWDBManager::setErrorHandler 
before instantiating the database.

void OutputDBStatus (const RWDBStatus& aStatus)
{
 if(aStatus.vendorError1() == 5701)
 ;
 else
 {
 // Print out the error.
 cerr << "Error code:" << (int) aStatus.errorCode() << endl
      << "Error message     " << aStatus.message() << endl
      << "Is terminal:      " << (aStatus.isTerminal() ? "Yes" : "No")<< endl
      << "Vendor error 1:   " << aStatus.vendorError1() << endl
      << "Vendor error 2:   " << aStatus.vendorError2() << endl
      << "Vendor message 1: " << aStatus.vendorMessage1()<< endl
      << "Vendor message 2: " << aStatus.vendorMessage2()<< endl;
  int num = aStatus.errorCode();
  if (num!= RWDBStatus::ok)
  {
   long severity = aStatus.vendorError2();
   if ( ( num!= RWDBStatus::vendorLib && num != RWDBStatus::serverMessage ) || severity > 0 )
   {
     throw aStatus;
   }
  }
 }
}

You could also set the errorHandler method on all of the DML statements
or storedprodcedure explicitly as follows

RWDBStoredProc sproc = db.storedProc("MyStoredproc",conn);
sproc.setErrorHandler(errorHandler);
