/*  ONLY USED FOR ODBC Version 2   -DODBCV2
*
*   Re-define everything to work (more-or-less) in an ODBC V2 environment 
*       Random access to retrieved rows is not supported - i.e. calls to apr_dbd_select() cannot
*       have a 'random' argument of 1.  apr_dbd_get_row() must always pass rownum as 0 (get next row)
