Using Dynamic Query in For Loop

Question

I have a doubt whether i can use the result from dynamic query in the for loop.
for example,
declare
v_sql varchar2(1000);
v_Id INTEGER;
begin
v_sql := 'select id from table1 where id in ('||v_Id||')';
FOR i in vsql LOOP
dbms_output.put_line(i.id);
end loop;
end;
The above query is possible ?

Answer 1

And here's a basic example of opening up a cursor for your dynamic query...

Wrote file afiedt.buf
  1  declare
  2    v_sql varchar2(2000);
  3    v_cur sys_refcursor;
  4    i     emp.sal%type;
  5  begin
  6    v_sql := 'select sal from emp';
  7    open v_cur for v_sql;
  8    loop
  9      fetch v_cur into i;
10      exit when v_cur%NOTFOUND;
11      dbms_output.put_line('Salary: '||i);
12    end loop;
13* end;
