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
