Question

我有一个RentTable

Mark      MonthlyRental   dailyRental   InDate        OutDate
-------------------------------------------------------------------
Mercedes    5000             166,67     01.01.2016    NULL
Renault     3000             100,00     01.01.2016    20.03.2016
Ford        4000             133,33     01.02.2016    NULL

我想做一个如下报告：

Mark    MonthlyRental   DailyRental    InDate       OutDate    January  February    March   April
---------------------------------------------------------------------------------------------------------
Mercedes    5000          166,67       01.01.2016   NULL        5000    5000    5000    5000
Renault     3000          100          01.01.2016   20.03.2016  3000    3000    2000    0
Ford        4000          133,33       01.02.2016   10.06.2016  4000    4000    4000    4000
