帮忙找到答案？

帮忙找出答案？？
写一个sql，表tab1字段A、B、C，C为创建时间，B为数字型，找到B在100到1000之间，创建时间最大的记录

我自己的弄的答案：Select * from(select rownum,A,B,C FROM tab1 where B between 100 and 1000 order by C) rownum =1;

现不知道这句是不是正确的，请高手指教，谢谢

[解决办法]
select max(C) FROM tab1 where B between 100 and 1000 order by C
or
select * from (
select rownum,A,B,C FROM tab1 where B between 100 and 1000 order by C) a 
order by b desc limit 1
