SQL query to select dates between two dates

Question

I have a start_date and end_date. I want to get the list of dates in between these two dates. Can anyone help me pointing the mistake in my query.<

Answer 1

if its date in 24 hours and start in morning and end in the night should add something like :

declare @Approval_date datetime
set @Approval_date =getdate()
Approval_date between @Approval_date +' 00:00:00.000' and @Approval_date +' 23:59:59.999'

Answer 2

select * from test 
     where CAST(AddTime as datetime) between '2013/4/4' and '2014/4/4'

-- if data type is different

Answer 3

I would go for

select Date,TotalAllowance from Calculation where EmployeeId=1
             and Date >= '2011/02/25' and Date < DATEADD(d, 1, '2011/02/27')

The logic being that >= includes the whole start date and < excludes the end date, so we add one unit to the end date. This can adapted for months, for instance:

select Date, ... from ...
             where Date >= $start_month_day_1 and Date < DATEADD(m, 1, $end_month_day_1)

Answer 4

SELECT Date, TotalAllowance  
FROM Calculation  
WHERE EmployeeId = 1 
  AND Date BETWEEN to_date('2011/02/25','yyyy-mm-dd') 
               AND to_date ('2011/02/27','yyyy-mm-dd');
