Count on table

Question

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

And you can squeeze a bit more performance out of the database by using analytic functions if you have at least an 8i database. This pushes the counting down to the level of the initial query, and prevents you from having to then run a 2nd, outer query.
<pre>
SELECT cod,
NAME
FROM (SELECT cod,
NAME,
COUNT (*) OVER (PARTITION BY cod) AS cnt
FROM occ)
WHERE cnt > 1;
