Native SQL "Table does not exist in database"

Question

Hi Developers,
I'm doing a database connection to an Oracle db and trying to read data using native SQL - I keep getting the runtime error "table does not exist in database" on the statement Fetch Next Cursor. The following is the code snippet (I've commented out the Exec SQL and Fetch Next to make sure I have a connection and I do). HR is a schema in the database and T_Donation is a table in HR.
Data: w1(3),
         c1 type cursor.
start-of-selection.
  if con_name is initial.
    write: 'No connection specified'.                       "#EC NOTEXT
    return.
  endif.
try to open the connection and catch the errors (if any)
  try.
      con_ref = cl_sql_connection=>get_connection( con_name ).
    catch cx_sql_exception into sqlerr_ref.
    error occured
      write:
        'Could not open connection', con_name, '.'.         "#EC NOTEXT
      if sqlerr_ref->unknown_connection = 'X'.
        write:
          / con_name, 'is not defined in DBCON'.            "#EC NOTEXT
      elseif sqlerr_ref->db_error = 'X'.
        write:
          / 'sql error', sqlerr_ref->sql_code, 'occured:',
          / sqlerr_ref->sql_message.                        "#EC NOTEXT
      else.
        perform get_trace_file using dev_file.
        write:
          / 'DBI error', sqlerr_ref->internal_error, 'occured.',
          / 'See trace file for further info:',
            icon_read_file as icon hotspot, dev_file.       "#EC NOTEXT
      endif.
      return.
  endtry.
connection successfully opened
  write:
    / 'Connection', con_name, 'successfully opened.'.       "#EC NOTEXT
*- Get the data from MS-SQL Server
  EXEC SQL.
    open C1 for
    SELECT HR.T_DONATION.DN_DONATIONYEAR
    FROM HR.T_DONATION
  ENDEXEC.
  do.
    EXEC SQL.
      FETCH NEXT C1 into :w1
    ENDEXEC.
    if sy-subrc = 0.
      perform loop_output.
    else.
      exit.
    endif.
  enddo.
  EXEC SQL.
    CLOSE C1
  ENDEXEC.
close connection again
  con_ref->close( ).
  write:
    / 'Connection', con_name, 'closed'.                     "#EC NOTEXT
end-of-selection.
*& Form LOOP_OUTPUT
Output
form loop_output .
  write: /5 w1.
endform. " LOOP_OUTPUT
Thanks for your help.
