query between separate date fields

i need to query between two datetime columns. Start date is given and need to calculate 90 days out from that date.

declare @StartDate as date, @EndDate as date
set @StartDate = '1/14/2013'
set @EndDate = dateadd(d,90,@StartDate)

query
where
cast(StartTimeLocal as Date) >= @StartDate
and cast(EndTimeLocal as Date) <=  @EndDate


problem is that i don't see all the rows. if i comment out: and cast(EndTimeLocal as Date) <=  @EndDate I see the rows.

example:
start date of 2013-01-14 06:00:00.000
end date of 2013-08-02 00:59:00.000

this row only shows when i comment out: and cast(EndTimeLocal as Date) <=  @EndDate otherwise it doesn't show.

how do i find the rows between those dates?

Use the below one for date filtering

Convert(Varchar,StartTimeLocal,101) >= @StartDate

are you saying

declare @StartDate as date, @EndDate as date
set @StartDate = '1/14/2013'
set @EndDate = dateadd(d,90,@StartDate)

select StartTimeLocal, EndTimeLocal from Schedules
where
Convert(Varchar,StartTimeLocal,101) >= @StartDate
and
 Convert(Varchar,StartTimeLocal,101) <= @EndDate
0

this still didn't show the row I'm looking for

select StartTimeLocal, EndTimeLocal from Schedules
where
Convert(Varchar,StartTimeLocal,101) >= @StartDate
and
 Convert(Varchar,EndTimeLocal,101) <= @EndDate

Use this below one

declare @StartDate as datetime, @EndDate as datetime
set @StartDate = '1/14/2013'
set @EndDate = dateadd(d,90,@StartDate)

select StartTimeLocal, EndTimeLocal from Schedules
where
Convert(Varchar,StartTimeLocal,101) >= @StartDate
and
 Convert(Varchar,StartTimeLocal,101) <= @EndDate

that shows the row I need but also shows beyond 90 days

declare @StartDate as datetime, @EndDate as datetime
set @StartDate = '1/14/2013'
set @EndDate = dateadd(d,90,@StartDate)

select @StartDate, @EndDate
--startdate = 2013-01-14
--enddate = 2013-04-14

this query goes way beyond the end date by showing data in the month of august:
select StartTimeLocal, EndTimeLocal from Schedules
where
Convert(Varchar,StartTimeLocal,101) >= @StartDate
and
 Convert(Varchar,StartTimeLocal,101) <= @EndDate

i just want to show all the rows between startdate and enddate not beyond the enddate

Run the below one and check

declare @StartDate as datetime, @EndDate as datetime
set @StartDate = '1/14/2013'
set @EndDate = Convert(Varchar,dateadd(d,90,@StartDate),101)

select StartTimeLocal, EndTimeLocal from Schedules
where
Convert(Varchar,StartTimeLocal,101) >= @StartDate
and
 Convert(Varchar,StartTimeLocal,101) <= @EndDate
