Declare @FromDate Date = '2014-04-21',
@ToDate Date = '2014-05-02'
;With
E1(N) As (Select 1 From (Values (1), (1), (1), (1), (1), (1), (1), (1), (1), (1)) DT(N)),
E2(N) As (Select 1 From E1 A Cross Join E1 B),
E4(N) As (Select 1 From E2 A Cross Join E2 B),
E6(N) As (Select 1 From E4 A Cross Join E2 B),
Tally(N) As
(
Select Row_Number() Over (Order By (Select Null))
From E6
)
Select DateAdd(Day, N - 1, @FromDate) Date
From Tally
Where N <= DateDiff(Day, @FromDate, @ToDate) + 1
