count on table

[raf]

have this table OCC

COD.............NAME
001.............TOM
001.............SAM
002.............CAT
003.............DOG
003.............SAM
003.............TOM
004.............JACK
005.............TOM
005.............SAM
........................
........................
........................
........................

I'd like to get just cod with more name:

I tried this
SELECT COUNT(NAME) TOT, COD
FROM OCC
GROUP BY COD
HAVING COUNT(NAME) > 1

OK, I get this:

TOT..........COD
2............001
3............003
2............005

but I'd like to get also the records.

For example I want this (only the records with more name):

COD.............NAME
001.............TOM
001.............SAM
003.............DOG
003.............SAM
003.............TOM
005.............TOM
005.............SAM

How can I write this query??

Thanks

select
s.tot, o.cod, o.name
from
occ o,
(select count(name) tot, cod
from occ
group by cod
having count(name) > 1) s
where
o.cod = s.cod

Bet this is faster ...

Select
   cod,
   name
From
   (
   Select
      cod,
      name,
      Count(*) Over (Partition By cod)
         row_per_cod
   From
      OCC
   )
Where
   row_per_code > 1

...or...

Select
   cod,
   name
From
   (
   Select
      cod,
      name,
      Count(distinct name) Over (Partition By cod)
         name_per_cod
   From
      OCC
   )
Where
   name_per_code > 1
