HI i need to convert this to an update and i have no success :(
Here is the select

select rn, rdt, id_cpt_inet, no_tel, dt_deb, dt_fin, dt_com, dt_eff_inet, cd_stat_approv, no_tp_compo
from (
  select
  rank() over (
    partition by no_tel, id_cpt_inet
    order by
        nvl (dt_com, to_date(19000101,'yyyymmdd')) desc,
        nvl (dt_fin, to_date(20090101,'yyyymmdd')) desc,
        nvl (dt_deb, to_date(20090101,'yyyymmdd')) desc
  )
     rn, rdt, id_cpt_inet, no_tel, dt_deb, dt_fin, dt_com, dt_eff_inet, cd_stat_approv, no_tp_compo
  from (
      select
      rank() over (
            partition by id_cpt_inet
            order by dt_eff_inet desc
      )
      rdt, id_cpt_inet, no_tel, dt_deb, dt_fin, dt_com, dt_eff_inet, cd_stat_approv, no_tp_compo
      from cleaned_sga_tpc
  ) where rdt =1
) where rn=1 and cd_stat_approv != 8 and cd_stat_approv != 1 and no_tp_compo = 11

I need to update the table cleaned_sga_tpc and for each of those record set it to the same value (1 for exemple), basically tagging my good records selected.

I tried with a select for update in a cursor and it seems to not like the analytics commands :(

Try this :
update cleaned_sga_tpc X
set <your col> = (select rn FROM
(
select rn, r_id
from (
  select
  rank() over (
    partition by no_tel, id_cpt_inet
    order by
        nvl (dt_com, to_date(19000101,'yyyymmdd')) desc,
        nvl (dt_fin, to_date(20090101,'yyyymmdd')) desc,
        nvl (dt_deb, to_date(20090101,'yyyymmdd')) desc
  )
     rn, r_id, rdt, id_cpt_inet, no_tel, dt_deb, dt_fin, dt_com, dt_eff_inet, cd_stat_approv, no_tp_compo
  from (
      select
      rowid rid,
      rank() over (
            partition by id_cpt_inet
            order by dt_eff_inet desc
      )
      rdt, id_cpt_inet, no_tel, dt_deb, dt_fin, dt_com, dt_eff_inet, cd_stat_approv, no_tp_compo
      from cleaned_sga_tpc
  ) where rdt =1
) where rn=1 and cd_stat_approv != 8 and cd_stat_approv != 1 and no_tp_compo = 11
)
where r_id = X.rowid )

This is the logic behind the solution i've given. You can make the changes and see how it works.

SQL> select * from tbl1;

        ID DT
---------- ---------
           28-NOV-07
           29-NOV-07
           27-NOV-07
           26-NOV-07

SQL> update tbl1 t
  2  set id = ( select rn
  3             from (select rowid r_id , row_number() over (order by dt) rn
  4                   from tbl1 )
  5             where r_id = t.rowid)
  6  /

4 rows updated.

SQL> select * from tbl1;

        ID DT
---------- ---------
         3 28-NOV-07
         4 29-NOV-07
         2 27-NOV-07
         1 26-NOV-07
