Split a row in sql server - sql

Question

In my DB, there are 2 tables ie RateCalendar & Blackout.
Ratecalendar stores daily, weekly, etc. rates between 2 dates for a Car Class. eg
From 10Jan to 27 May 2016, Daily rates are say £20,
weekly rates are £50 and so on.
Similarly, for other Dates range daily weekly rates are specified.
Suppose for 2 days (4May to 5May) I blackout my car ie car won't be available for a location. Now, I have to show the record as splitted ie from 10Jan to 3May, Cars will be available ie IsAvailable->True.
From 4th May to 5th May as Blackout (ie IsAvailable->False) and
from 6th till 29May again cars will be available.
All records will not split. Only those Cars whose details are present in blackout will split.
Moreover, depending on Blackout dates, splitting will be done. For eg. in blackout if there are two records for a car ie car is blacked out for say 10Jan to 12Jan And 4th May to 5th May, then, output will be like:
Car StartDate EndDate Available
Car1 10Jan2016 12:00 12Jan2016 1:00 N
Car1 12Jan2016 1:00 4May2016 9:00 Y
Car1 4May2016 9:00 5May2016 12:00 N
Car1 5May2016 12:00 27May2016 12:00 Y
Car2 10Jan2016 10:00 27May2016 12:00 Y
So, row can be splitted into 0 or 2 or multiple depending on Blackout dates for car.
What's the best way to do this?
Below is the layout of
1) RateCalendar Table(there are 2 more fields AgencyId,LocationId as shown in Blackout Table)
RateCalId RateGroupId CarClassId StartDate EndDate DailyRate
1 1 1 10Jan2016 10:00 26May2016 11:00 20
2 1 1 27May2016 11:00 28June2016 12:00 40
2) Blackout Table
BlackoutId AgencyId LocationId BeginDate EndDate
1 1 1 10Jan2016 12:00 12Jan2016 1:00
2 1 1 4May2016 9:00 5May2016 12:00
3) BlackoutCars
BlackoutId CarId
1 1
1 2
2 1
2 2
4) BlackoutRateGroup
BlackoutId RategroupId
1 1
1 0(0=>all)
2 3
