试试这个：
with Mth (st, nd) as (
select DATEADD (M, datediff (m, 0,'2012-09-01'), 0),
DATEADD (M, DATEDIFF (m, 0, '2012-09-01') + 1, 0)
union all
select DATEADD (m, 1, st),
DATEADD (m, 1, nd)
from Mth
where nd <= DATEADD (m, datediff (m, 0, getdate()), 0)
), PiVoted
AS
(
select *
from
(
select MONTH(Mth.st) Month,

COUNT(S.QRY_ID) Searches
FROM Mth
LEFT JOIN SEARCHES S
on Mth.st <= S.CREATED
and Mth.nd > S.CREATED
LEFT JOIN MEMBERS U

GROUP BY YEAR(Mth.st), MONTH(Mth.st), U.HOLDER_LOGIN
) src
pivot
(
sum(searches)
for month in ([12],[11],[10])
) piv
)
SELECT *
FROM PiVoted
