To execute the same stored procedure multiple times

Question

Suppose I have this :
select distinct batch_id, submit_date from batch where date > xxx;
Gives me :
301
305
306
Currently, I have a stored procedure PROC_A that has 3 cursors all of which have a field called batch_id(which ofcourse exists in the above batch table). Hence, when I run as of today
EXECUTE PROC_A;
This could process an unpredictable set of batch ids. I am looking to avoid this.
What I am trying to achieve here is :
When I do,
select distinct batch_id from batch where date > xxx;
301
305
306
For each of the above values, I want to call the PROC_A exclusively. In other words, by one shot, I want this procedure to be invoked 3 times, each time processing just one batch_id one after another (rather than passing those 3 values to the procedure and having it execute just once !). I also want to avoid using the batch table anywhere inside the stored procedure PROC_A.
How do I achieve this ? If another stored procedure can call PROC_A, I am okay with including the batch table there.

Answer 1

What about an executed_date field on the table and a "where rownum=1" in the cursor?
proc_a
begin
     begin
          select batch_id
          into b_id
          from batch ...
          where date > xxx
               and date > last_executed
               and rownum = 1;
     exception
          when NO_DATA_FOUND then
               return;
     end;
     exec(b_id);
     update batch
     set last_executed = sysdate
     where bacth_id = b_id;
     return;
end;Bye Alessandro
