(2,'2014-01-01 01:00:00.000',5),
(2,'2014-01-01 02:00:00.000',80)

Result Needed:

CustomerId TranDate     TranCount-A  TranCountB
1                2014-01-01   5                  5
1                2014-01-02   0                  15
1                2014-01-03   5                  15
1                2014-01-04   80                15
2                2014-01-01   0                  80

TranCount-A : This is the values that appeared the latest in that day.

TranCount-B : This is the value that appeared the latest in that day. But after this day the value
needs to continue till the point the value got changed in some other day.
