如何比较两个年龄一个年龄，其他年龄计算年龄为ms sql server2008

WHERE sites.site_type = 3 AND o.order_date > '2015-10'

我得到fname，lname和calcAge

这是表中给出的年龄

select FNAME,LNAME, cast(datediff(DAY,DOB, '03-OCT-2015') /
(365.23076923074) as int) as 'calcAge' from students1 order by Age asc

这个calcage需要与学生表中的年龄进行比较，如果该年龄匹配则应该返回true，否则

 insert into students values(1, 'Jon', 'Smith', 30, '10-FEB-2000');
 insert into students values(2, 'Jane', 'Smith', 20, '12-FEB-1993');
 insert into students values(3, 'Joan', 'Smith', 75, '16-OCT-1938');
 insert into students values(4, 'Joanne', 'Smith', 18, '20-JUN-1995');

它的返回错误。请纠正我

       , CASE WHEN cast(datediff(DAY,DOB, '03-OCT-2015') /(365.23076923074) as int) 
                   = Age 
              THEN 1 ELSE 0 END AS AgeCompare
