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

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)
