Either of these.SELECT Account, room
FROM Tbl
GROUP BY Account
HAVING COUNT(*) = 1
SELECT Account, Room FROM (
SELECT Account, Room,
COUNT(*) OVER (PARTITION BY account) AS N
FROM Tbl
) s WHERE N=1 |

which values you want to exclude?
Entire Account records or just duplicate instances?
What would be output for above sample data?

then previous suggestion would work for you
or even this
SELECT Account, Room
FROM Tbl t
WHERE NOT EXISTS(SELECT 1
FROM Tbl
WHERE Account = t.Account
AND Room <> t.Room
)

I´m very grateful for answer. But its bit confusing me. Do you mean query like this?
select
t1.account,
t1.room,
t1.booked
from (
select
account,
room,
sum(booked)
from Table1
join ...
where ...
group by
account,
room)t1
where not exists (select 1 from t1 where t1.account =account and room <>t1.room
group by
select
t1.account,
t1.room,
t1.booked

yon can use both ways as they're equivalent
But NOT EXISTS might have slight upper hand as it relies on boolean result rather than performing aggregation to find count
