I don't understand why this subquery doesn't work. If I replace the subquery with a View it works. I am trying to determine the number of "active accounts" in a group of transactions during December. What am I missing?

SELECT salesrun_id, Count(account_id) FROM
(SELECT salesrun_id, account_id FROM Trades t
WHERE t.date > '2007-12-01'
GROUP BY t.salesrun_id, t.account_id)

Msg 102, Level 15, State 1, Line 4
Incorrect syntax near ')'.

Try adding an alias to the subquery and then complete your aggregate with a final group by clause:

SELECT salesrun_id, Count(account_id) FROM
(SELECT salesrun_id, account_id FROM Trades t
WHERE t.date > '2007-12-01'
GROUP BY t.salesrun_id, t.account_id) a
GROUP BY salesrun_id
