    CCFXStringSet* pColumns = pQuery->GetColumns() ;
    int nNumColumns = pColumns->GetCount() ;
     
    // Print the list of columns to the user
    pRequest->Write( "Columns in query: " ) ;
    for( int i=1; i<=nNumColumns; i++ )
    {
        pRequest->Write( pColumns->GetString( i ) ) ;
        pRequest->Write( " " ) ;
    }
