Exceptions for cursor definition

Question

Select statement of parametric cursor in DECLARE section fetches no records based on some id. I have one error table and populating with these type of ids'. Here control is not going to exception block because succeeding block of declare section is begin section. Please let me know how trap these ids'.
Thank you.

Hi
A cursor for loop does not raise NODATA_FOUND. If you want to raise NO_DATA_FOUND then use an explict open and fetch.
declare
cursor dept_cur is
select deptno
from dept;
cursor emp_cur (dno number) is
select empno,ename
from emp
where deptno = dno;
emprec emp_cur%ROWTYPE
begin
for dept_rec in dept_cur
loop
begin
open emp_cur(dept_rec.deptno);
loop
fetch dept_cur into deptrec;
raise NO_DATA_FOUND when dept_rec%NOTFOUND;
end loop;
close emp_cur;
exception
when no_data_found
then insert into err_table values
(dept_rec.deptno);
end;
end loop;
end;HTH
