Exception Not Handled.

Question

Hi all,
Can you please explain why the exception is not handled even thought i have handled it by mentioning others.
declare
procedure empnetsal (vempno emp.empno%type) is
netsal number;
begin
select sal into netsal from emp where empno = vempno;
netsal := netsal+(netsal* 0.01)+netsal;
dbms_output.put_line (netsal);
exception
when no_data_found then
dbms_output.put_line ('Such employee does not exist');
when others then
dbms_output.put_line ('Exception handled by Others handler');
end;
begin
empnetsal ('string');
empnetsal (7566);
empnetsal (7788);
end;
regards,
Sri Ram.

Answer 1

The Exception handler is inside the Local Procedure and not in the anonymous block.
The block errors out before it enters into the procedure bacuase of wrong datatype.
Catching the error in the Block will solve your problem.
