Loop Cursor Fetch Insert Rows Into Global Temporay Table

Question

Hi friends,
I want to know there where is the problem in my this query
cursor c1 is select empno
from scott.emp;
b number;
begin
open c1;
     loop
     fetch c1 into b;
     exit when c1%notfound;
insert into scheema.a1
(a)
values
(b);
commit;
     end loop;
     close c1;
end;
There is no any error displaying while proceeding this query but the table a1 which is (Global temporary table with ON COMMIT PRESERVE ROWS option enabled) does not gets any records. Kindly let me know the problem.
Regards.

Answer 1

Are you sure that the query returns date? Are you checking the table via the same session?
SQL> create global temporary table a1 (
  a  number)
  on commit preserve rows
Table created.
SQL> declare
   cursor c1 is select empno
      from scott.emp;
   b number;
begin
   open c1;
   loop
      fetch c1 into b;
      exit when c1%notfound;
      insert into a1
      (a)
      values
      (b);
      commit;
   end loop;
   close c1;
end;
