我想要一个查询，它只选择那些具有指定年份数据的月份，但我不太确定如何实现这一点。这是我到目前为止所得到的：

select MONTH(DateRaised) as 'Month'
from Complaints
where
    (select COUNT(*)
     from Complaints
     where YEAR(DateRaised) = 2000) > 0
group by MONTH(dateraised)
order by MONTH(dateraised)

因此，如果我的数据在 2000 年 5 月、8 月和 12 月有投诉，那么我只想5, 8 and 12出现在我的查询中，这可能吗？
