求一条sql语句

表
F_DateTime              F_Money
2009-07-01 04:00:00    100
2009-07-01 06:01:00    100
2009-07-01 07:10:00    100
2009-07-01 08:20:22    100
2009-07-02 01:20:30    100
2009-07-02 05:23:30    100
2009-07-02 07:24:30    100


统计 每天的 06:00:00 到下一天的 05:59:59 的数据 算一天的数据

F_DateTime between '2009-06-30 06:00:00' and '2009-07-03 05:59:59'
结果像这样
F_Date      F_Money
2009-06-30  100
2009-07-01  500
2009-07-02  100
