Not pretty but it should work:

SQL> create or replace procedure emprec   2 is
  3 cursor empcursor is
  4 select empno, recno from emptest order by empno for update of recno;
  5 v_empno number := 99999;
  6 v_count number := 0;
  7 begin
  8 for x in empcursor loop

  9      if x.empno <> v_empno then v_count:=1;
 10         v_empno := x.empno;
 11      end if;
 12      update emptest
 13         set recno = v_count
 14       where current of empcursor;
 15       v_count:=v_count+1;

16 end loop;
17 end emprec;
18 /

Procedure created.

SQL> execute emprec;

PL/SQL procedure successfully completed.

SQL> commit;

Commit complete.

SQL> drop procedure emprec;

Procedure dropped.

I have a 10000-rows table with 2 columns, Emp_ID and Req_ID.

There are about 150 different emp_ids in these 10000+ records.

What I want to do is the following:

For every different Emp_id, I need the Rec_ids that corresponds to it to be updated/renumbered starting from 1 and keep going up by 1.

So I want it to look something like this:

Emp_ID Req_ID

10001       001
10001       002
10001       003
10001       004
10001       005
10001       006
10001       007
10001       008


10002       001
10002       002
10002       003
10002       004
10002       005


10003       001

10004       001
10004       002
10004       003
10004       004
10004       005
10004       006

etc

Any ideas?

Thanks,
maa
