Although you've had a row-at-a-time version
from someone, you might try something like
the following if you can't do a "create as
select" to rebuild the original data.
Create table temp
pctfree 0
nologging
as
select
rowid e_rowid,
row_number() over (PARTITION BY DEPTNO order by deptno) x
from emp;
create unique index t_i on temp(e_rowid);
alter table temp modify e_rowid not null;
update emp e
set
req_id = (
select x from temp t
where t.e_rowid = e.rowid
);
(Just making it up as I go along, so I won't
guarantee that it works).
