T-SQL查询获取月份列表中的最后一个值

Question

以下是我的数据

date            value
30/03/2014  625949
23/03/2014  624549
16/03/2014  623149
09/03/2014  621549
02/03/2014  619749
23/02/2014  617749
16/02/2014  616149
09/02/2014  614549
02/02/2014  612949
19/01/2014  609749
12/01/2014  608149
06/01/2014  606749

如果我想只获得一个月中的最后一个值，例如下面的输出，我怎么能得到它？

date            value
30/03/2014  625949
23/02/2014  617749
19/01/2014  609749
