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'
