如何实现同时对时间，年份机型比较？－－－在线等待。

select CASE MONTH(OccurenceDate)
WHEN MONTH(2003-01-17) THEN OccurenceQty ELSE 0 END as n12, OccurenceCode
from t_Summary where InOutName='1'
以上只是对所有的一月份进行了统计，如何实现年份的比较？
如以上的例子：比较的是2003年1月份。
（要求不能在where中写语句。。。。）

select CASE WHEN YEAR(OccurenceDate)=YEAR(2003-01-17) and MONTH(OccurenceDate)=MONTH(2003-01-17) THEN OccurenceQty ELSE 0 END as n12, OccurenceCode
from t_Summary where InOutName='1'

[CCEO]

select CASE WHEN YEAR(OccurenceDate)=YEAR('2003-01-17') and MONTH(OccurenceDate)=MONTH('2003-01-17') THEN OccurenceQty ELSE 0 END as n12, OccurenceCode
from t_Summary where InOutName='1'

[愉快的登山者]

WHEN datepart(MONTH, '2003-01-17') = 1 THEN OccurenceQty ELSE 0 END as n12
