SQL query need to get names where count(id) = 2

Question

I have a table programparticipants. I am currently successfully querying the IDs where count(name) > 1. What I need now is to query the names that belong to those IDs where count(name) > 1.

Example, data result currently being returned:

ID     count(name)
1      2
3      4
4      3

Example, data result needed:

ID     name
1      nm1
1      nm3
3      nm2
3      nm3
3      nm4
3      nm7
4      nm5
4      nm8
4      nm9

Answer 1

select count(id), name 
from programparticipants 
group by name 
having count(id) > 1

Answer 2

You may use this:

SELECT 
   (SELECT name FROM participants WHERE id=p.participantid) AS name
FROM
   programparticipants AS p
WHERE
   .... (the part where you find count(name)>1)
