Maybe you mean this 

SELECT MAIN.* FROM ReleaseTerritoryPrice MAIN
WHERE MAIN.ReleaseId in (
    SELECT rtp.ReleaseId
    FROM   ReleaseTerritoryPrice rtp
    WHERE rtp.TerritoryId =200
    GROUP BY rtp.ReleaseId
    HAVING COUNT(rtp.TerritoryId) =1 )

You can use the following with NOT EXISTS in a WHERE clause:

select rtp1.releaseId, rtp1.territoryId
from ReleaseTerritoryPrice rtp1
where rtp1.territoryId = 200
  and not exists (select releaseId
                  from ReleaseTerritoryPrice t2
                  where t2.territoryId <> 200
                    and rtp1.releaseId = t2.releaseId);

See SQL Fiddle with Demo

Or you can use NOT IN in a WHERE clause:

select rtp1.releaseId, rtp1.territoryId
from ReleaseTerritoryPrice rtp1
where rtp1.territoryId = 200
  and rtp1.releaseId not in (select releaseId
                              from ReleaseTerritoryPrice t2
                              where t2.territoryId <> 200);

A couple of ways

SELECT ReleaseId
FROM   ReleaseTerritoryPrice
WHERE  TerritoryId = 200 
EXCEPT
SELECT ReleaseId
FROM   ReleaseTerritoryPrice
WHERE  TerritoryId IS NULL OR TerritoryId <> 200

Or

SELECT ReleaseId
FROM   ReleaseTerritoryPrice
GROUP BY ReleaseId
HAVING COUNT(DISTINCT TerritoryId) =1 AND MAX(TerritoryId )=200

Use the DISTINCT keyword.

select DISTINCT rtp.ReleaseId, 
     rtp.TerritoryId  
from ReleaseTerritoryPrice rtp 
where rtp.TerritoryId=200
