Help need for procedure with "cursor in a cursor"

Question

Hi
Iam using two cursors in my procedure.
Create SP_sample as
cursor C1 is
select a from A
cursor C2 is
select
a,bc,d from A,B where A.a=B.a
Begin
For Cur_rec C1 loop
For Cur_rec1 C2 loop
"SELECT QUERY"
end loop
end loop
end
1)the "SELECT QUERY" is working fine in Toad or sql editor.
2)The procedure is compiled without any errors
But when I am executing the procedure I am getting the error
ORA-01403: no data found
ORA-06512: at the line where "SELECT QUERY" is starting
ORA-06512: at line 1
can you please suggest what are the things I should be checking.
Thanks

Could you provide a more complete example of what you are doing.
Your example is vague on the details, and it appears that you have 2 cursors both selecting from table A that you are looping through in a nested fashion, but your inner cursor is not correlated with your outer cursor. Also you have skimped on the details of the select you are trying to perform in the inner most loop of your code, and there is no indication that it has any correlation to the two outer cursors, and to top it off you have completely left out any syntactic punctuation.
why not rewrite your code thusly:
declare
  cursor c1 is select a from a;
  cursor c2(p_a a.a%type) is select bc, d from b where b.a = p_a;
begin
  for cur_rec in c1 loop
    for cur_rec1 in c2(cur_rec.a) loop
      select ...
      into ...
      from ....
      where ??= cur_rec.a
      and ??=cur_rec1.bc
      and ??=cur_rec1.d;
    end loop;
  end loop;
end;
