SQL SERVER: Get total days between two dates

I'm trying to get the total number of days between two days:

1/1/2011
3/1/2011

RETURN
62

Is it possible to do in SQL Server?

PRINT DATEDIFF(DAY, '1/1/2011', '3/1/2011') will give you what you're after.

This gives the number of times the midnight boundary is crossed between the two dates. You may decide to need to add one to this if you're including both dates in the count - or subtract one if you don't want to include either date.

SQL Server DateDiff

DECLARE @startdate datetime2 = '2007-05-05 12:10:09.3312722';
DECLARE @enddate datetime2 = '2009-05-04 12:10:09.3312722'; 
SELECT DATEDIFF(day, @startdate, @enddate);

You can try this MSDN link

DATEDIFF ( datepart , startdate , enddate )
SELECT DATEDIFF(DAY, '1/1/2011', '3/1/2011')

See DateDiff:

DECLARE @startdate date = '2011/1/1'
DECLARE @enddate date = '2011/3/1'
SELECT DATEDIFF(day, @startdate, @enddate)

Another date format

select datediff(day,'20110101','20110301')

SELECT DATEDIFF(day, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');

This is working for me -

SELECT DATEDIFF(DAY, startdate, enddate) AS DayCount

Example : SELECT DATEDIFF(DAY, '11/30/2019', GETDATE()) AS DayCount

if you want to do same thing Store Procedure then you need to apply below code.

select  (datediff(dd,'+CHAR(39)+ convert(varchar(10),@FromDate  ,101)+ 
 CHAR(39)+','+CHAR(39)+ convert(varchar(10),@ToDate  ,101) + CHAR(39) +')) 
 Daysdiff

where @fromdate and @todate is Parameter of the SP

DECLARE @FDate DATETIME='05-05-2019' /*This is first date*/
 GETDATE()/*This is Current date*/
SELECT (DATEDIFF(DAY,(@LastDate),GETDATE())) As DifferenceDays/*this query will return no of days between firstdate & Current date*/
