Question

I have one table with columns stamp_type and amount as follows

                          stamp_type                          | amount
--------------------------------------------------------------+--------
 GENERAL STAMP                                                |  11000
 GENERAL STAMP                                                |  25000
 COURT FEE STAMP                                              |   9800
 SPECIAL ADHESIVE                                             | 721000
 GENERAL STAMP                                                | 125000
 COURT FEE STAMP                                              |  21000

    GENERAL STAMP                                                   161000
    COURT FEE STAMP                                                 30800
    SPECIAL ADHESIVE                                                721000

try this code::

    from tbl
    group by stamp_type
 union
 select 'Total:' stamp_type,sum(amount) amount
 from tbl;
