You can raise user defined exception when there are no records updated by checking the value of SQL%ROWCOUNT.
for example

declare
x number;
no_data exception;
begin

        update a set c1 = 2 where c1 = 6;
        x := sql%rowcount;
        if x = 0 then
                raise no_data;
        end if;
exception
        when no_data then
                dbms_output.put_line('0 Rows Updated');

end;

Hi all,

Do you know if an exception is raised for "0 rows updated." Take the following scenario but using PL/SQL.

select * from a;
C1
1
1
1
1

You get:
update a set c1 = 5 where c1 = 6;
0 rows updated.

Thanks
Kumanan
