It's difficult to explain in the title.
I have rows such as:
ID MYNAMES
1 .
1 AAA
1 BBB
2 .
3 .
4 .
4 BBB

What i want to do is include all the rows but when a row has a dot and a row also has another MYNAMES on the SAME ID then i want to exclude the dot.
So the above would select

ID MYNAMES
1 AAA
1 BBB
2 .
3 .
4 BBB

I tried with having count but i don't think will work.
I can simply use where MYNAMES <> '.' but that will also exclude the rows that only have a dot and no other data, and i don't want to do that.
Any help?
Thanks.

DECLARE	@Sample TABLE

	);

INSERT	@Sample
VALUES	(1, '.'),
	(1, 'AAA'),
	(1, 'BBB'),
	(2, '.'),
	(3, '.'),
	(4, '.'),
	(4, 'BBB');

-- SwePeso
WITH cteSource(ID, MyNames, Yak)
AS (
	SELECT	ID,
		MyNames,
		MAX(MyNames) OVER (PARTITION BY ID) AS Yak
	FROM	@Sample
)
SELECT	ID,
	MyNames
FROM	cteSource
WHERE	MyNames <> '.'
	OR Yak = '.'
