I have three var char values as
#hour = '18'
#minute = '25'
#seconds = '45'
I need output in the form of '18:25:45'
Select from Convert(Time,#hour+#minute+#seconds)
values in hour minute and seconds coming from SSRS report drop down
You can 'add-up' the values from zero, like this:
declare #hour smallint = 18
declare #minute smallint = 25
declare #seconds smallint = 45
declare #result time
SELECT #result = DATEADD(hour, #hour, DATEADD(minute, #minute, DATEADD(second, #seconds, 0)))
An implicit conversion is not allowed. One solution could be to organise the format as a string and then convert to time as below.
declare #hour smallint = '18'
declare #minute smallint = '25'
declare #seconds smallint = '45'
declare #format varchar(8) = (select (CAST(#hour as varchar(2)) + ':'+ CAST(#minute as varchar(2))+':'+ CAST(#seconds as varchar(2))))
select CAST(#format as time)
Try with this 24-H date format, It will Work.
SELECT CONVERT(VARCHAR(8),GETDATE(),108) AS TimeResult
I am developing Time management system for employees.
I want the duration how much duration employee come late , or he went early.
i have following structure.
**Attendace**
AutoId --uniqueidentifier
EMployeeId --uniqueidentifier
Date --datetime
InTime -- varchar(50)
OutTime -- varchar(50)
ActualInTime--datetime
ActualOutTime--datetime
I want Late Coming Report ( i.e. who came late in morning after ActualInTime and how much duration in hh:mm:ss ) and also want early going(i.e who went early in the evening before ActualOutTime in duration in format hh:mm:ss )
So can you please help me..???
I came across an easier way of solving this issue.
First, a quick example of turning a "number of seconds" into the "hh:mm:ss" format.
DECLARE #NumberOfSeconds int
SET #NumberOfSeconds = 3843 -- 1 hour, 4 minutes, 3 seconds
SELECT #NumberOfSeconds AS 'seconds',
CONVERT(varchar, DATEADD(second, #NumberOfSeconds, 0), 108) AS 'hh:mm:ss'
This will give us this output:
And we can easily take this a step further, calculate the number of seconds between two datetimes, and display it in hh:mm:ss format:
DECLARE
#NumberOfSeconds int,
#StartTime datetime = '2017-09-14 14:16:11',
#EndTime datetime = '2017-09-14 14:23:13'
SET #NumberOfSeconds = DATEDIFF(second, #StartTime, #EndTime)
SELECT #NumberOfSeconds AS 'seconds',
CONVERT(varchar, DATEADD(second, #NumberOfSeconds, 0), 108) AS 'hh:mm:ss'
Which gives us this output:
Simple, hey ?
(And yes, you can simplify it further by putting the DATEDIFF directly into the DATEADD function.)
You can do it in a very simple way:
declare #date1 datetime, #date2 datetime
set #date1=DATEADD(s,-638,getdate())
set #date2=GETDATE()
select convert(char(8),dateadd(s,datediff(s,#date1,#date2),'1900-1-1'),8)
... the result is 00:10:38 (638s = 600s + 38s = 10 minutes and 38 seconds)
Another example:
select distinct convert(char(8),dateadd(s,datediff(s, CRDATE , GETDATE() ),'1900-1-1'),8) from sysobjects order by 1
It will works until the difference of 86399 seconds (23:59:59):
select convert(char(8),dateadd(s,datediff(s
, DATEADD(s,-86399,GETDATE())
, GETDATE()
),'1900-1-1'),8)
... after that it will return to zero:
select convert(char(8),dateadd(s,datediff(s
, DATEADD(s,-86400,GETDATE())
, GETDATE()
),'1900-1-1'),8)
Because they are the same day (you don't have to worry about number of hours >24), you can just use a combination of DATEDIFF(second,time1,time2) and DATEADD(second,0,) to get a datetime value.
To format to hh:nn:ss, use convert(char(8),answer,8) but this is something better done by the reporting front end against the datetime result.
-- Late report
select *, dateadd(s,0,datediff(s,intime,actualintime)) late_by
from attendance
where intime < actualintime
this code might help you...
DECLARE #First datetime
DECLARE #Second datetime
SET #First = '04/02/2008 05:23:22'
SET #Second = getdate()
SELECT DATEDIFF(day,#First,#Second)*24 as TotalHours,
DATEDIFF(day,#First,#Second)*24*60 as TotalMinutes,
DATEDIFF(day,#First,#Second)*24*60*60 as TotalSeconds
well, yes, you need to use DATEDIFF, and yes, all that posted above works, but, if you want to show 07:07:07 instead of 7:7:7, you have to do something like this:
Declare #starttime datetime, #endtime datetime, #seconds int, #minutes int, #hours int
Set #starttime ='2013-10-01 05:05:17'
Set #endtime = '2013-10-01 23:10:18'
set #hours = DateDiff(hour, #starttime, #endtime)
set #minutes = DateDiff(minute, #starttime, #endtime);
set #seconds = DateDiff(second, #starttime, #endtime);
select case when DateDiff(minute, #starttime, #endtime) > 60
then CASE WHEN #hours >= 10 THEN cast(#hours as varchar(3))
ELSE '0' + cast(#hours as varchar(3)) END +':' +
CASE WHEN #minutes - (#hours * 60) >= 10 THEN
cast((#minutes - (#hours * 60)) as varchar(3))
ELSE '0' +cast((#minutes - (#hours * 60)) as varchar(3)) END
+ CASE WHEN (#seconds - (#minutes *60)) >= 10 THEN
+':' + cast(#seconds - (#minutes *60) as varchar(10))
ELSE ':0' + cast(#seconds - (#minutes *60) as varchar(10)) END
ELSE '0' + cast(#minutes as varchar(3)) +':' + cast(#seconds as varchar(10))
end
It may not look very nice, but it gave me what i wanted.
How about using CAST.
,CAST (Table1.DateTimeLatest-Table1.DateTimeFirst as time) as [Elapsed Time]
The raw result from SSMS from an apparatus table:
SQL Return shows out to nanoseconds in this Data.
For the report, as pasted in formatted Excel sheet:
Formatted result column as hh:mm:ss.
SELECT id, pickupdateandtime, GETDATE() AS CurrentTime,
((DATEDIFF(day,GETDATE(),pickupdateandtime)) - 1) AS Days ,
convert(char(8),dateadd(s,datediff(s,GETDATE(),pickupdateandtime),'1900-1-
1'),8) AS 'Hours & Mins' FROM orders
Here's what worked for me. Thank you #lynx_74.

Create a stored procedure to do the work and then just call the procedure passing your start and end dates.

SELECT #years = #years-1

GO
Then just call using:
DECLARE #return_value int, #Duration varchar(100)
EXEC #return_value = [dbo].[GetOperationDuration] #DurationStart, #DurationEnd, #Duration = #Duration OUTPUT
SELECT #Duration as N'#Duration'
Thought I'd share my 2 cents. This fixes the overflow problems but only works with datetime not datetime2. It probably does not work with leap years or when clocks go backwards/forwards. I haven't tested with either.
declare #startTime datetime = getdate()
declare #endTime datetime
select [StartDate] = #startTime,
[EndDate] = #endTime,
[DD:HH:MM:SS.MS] = right( '00' + convert( varchar(20), datediff(hh, 0, #endTime - #startTime ) / 24 ), 2) + ':' +
right( '00' + convert( varchar(20), datediff(hh, 0, #endTime - #startTime ) % 24 ), 2) + ':' +
substring( convert( varchar(20), #endtime - #startTime, 114 ),
charindex( ':', convert( varchar(20), #endTime - #startTime, 114 ) ) + 1,
len( convert( varchar(20), #endTime - #startTime, 114 ) ) )
How can I get the whole time like this datediff(time, logindate, logoutdate)
I know this built-in function doesn't accept time argument but how can I get the whole time rather than minute, millisecond, second etc. ?
logindate datetime2
logoutdate datetime2
I want something like 1:05:45 rather than portion of it.
Try this
create table dbo.UserLog (UserID VARCHAR(32),loginDate DATETIME,logoutDate DATETIME)
insert into userLog VALUES ('SPARKY','11/14/2009 3:25pm',getDate())
insert into userLog VALUES ('JANNA','11/14/2009 10:45am',getDate())
select UserId,loginDate,logoutDate,
convert(varchar(12),dateAdd(mi,datediff(mi,logindate,logoutdate),'Jan 1 1753 12:00AM'),114) as timeSpent
FROM userLog
Basically, adding the minutes difference between the dates to the earliest valid SQL date and returning the value formatted as a time.
To have difference in days:
select cast(logoutdate - logindate as float) from table_name
or just
select logoutdate - logindatefrom table_name
You can evaluate days, hours, minutes from it.
EDIT
To have it formatted as time:
SELECT CONVERT(VARCHAR,DATA_KOSZTU - DATA_OST_ZMIANY,108) FROM TR_KOSZT
It will work if users are not logged for more than 24 hours, because CONVERT is used to format datetime, not timespan.
Because MSSQL do not have timepsan datatype, datediff returning in absolute integer from milliseconds to years should be enough for you to create a instance of say TimeSpan in .NET.
What Sql Server version are you talking about? In SQL Server 2000 and later, at least,
SELECT datediff(ss,'2006-11-10 05:47:53.497','2006-11-10 05:48:10.420')
will give you the difference between those two datetimes in seconds.
E.g.
select CONVERT(varchar(10),GETDATE(),108)
Here's the solution you are looking for.
DECLARE #Date1 datetime
DECLARE #Date2 datetime
SET #Date2 = '2006-11-15 07:26:25.000'
SET #Date1 = '2009-11-15 05:35:45.000'
-- -----------------------
-- Math done by hand 1:50:40
--
DECLARE #TotalSeconds bigint
DECLARE #Hours bigint
DECLARE #Minutes bigint
DECLARE #Seconds bigint
DECLARE #HH varchar(20)
DECLARE #MM varchar(2)
DECLARE #SS varchar(2)
DECLARE #Result varchar(50)
--
SET #TotalSeconds = datediff(ss,#Date1 ,#Date2)
SET #Hours = FLOOR(#TotalSeconds / 3600)
SET #TotalSeconds = #TotalSeconds % 3600
SET #Minutes = FLOOR(#TotalSeconds / 60)
SET #Seconds = #TotalSeconds % 60
--
SET #HH = CAST(#Hours as varchar)
SET #MM = CAST(#Minutes as varchar)
SET #SS = CAST(#Seconds as varchar)
IF #Minutes < 10 SET #MM = '0' + #MM
IF #Seconds < 10 SET #SS = '0' + #SS
--
SET #Result = #HH + ':' + #MM + ':' + #SS
SELECT #Result
Is there any way to take the difference between two datetime in sql server?
For example, my dates are
2010-01-22 15:29:55.090
2010-01-22 15:30:09.153
So, the result should be 14.063 seconds.
Just a caveat to add about DateDiff, it counts the number of times you pass the boundary you specify as your units, so is subject to problems if you are looking for a precise timespan.
e.g.
select datediff (m, '20100131', '20100201')
gives an answer of 1, because it crossed the boundary from January to February, so even though the span is 2 days, datediff would return a value of 1 - it crossed 1 date boundary.
select datediff(mi, '2010-01-22 15:29:55.090' , '2010-01-22 15:30:09.153')
Gives a value of 1, again, it passed the minute boundary once, so even though it is approx 14 seconds, it would be returned as a single minute when using Minutes as the units.
SELECT DATEDIFF (MyUnits, '2010-01-22 15:29:55.090', '2010-01-22 15:30:09.153')
Substitute "MyUnits" based on DATEDIFF on MSDN
SELECT DATEDIFF(day, '2010-01-22 15:29:55.090', '2010-01-22 15:30:09.153')
Replace day with other units you want to get the difference in, like second, minute etc.
I can mention four important functions of MS SQL Server that can be very useful:
1) The function DATEDIFF() is responsible to calculate differences between two dates, the result could be "year quarter month dayofyear day week hour minute second millisecond microsecond nanosecond", specified on the first parameter (datepart):
select datediff(day,'1997-10-07','2011-09-11')
2) You can use the function GETDATE() to get the actual time and calculate differences of some date and actual date:
select datediff(day,'1997-10-07', getdate() )
3) Another important function is DATEADD(), used to convert some value in datetime using the same datepart of the datediff, that you can add (with positive values) or substract (with negative values) to one base date:
select DATEADD(day, 45, getdate()) -- actual datetime adding 45 days
select DATEADD( s,-638, getdate()) -- actual datetime subtracting 10 minutes and 38 seconds
4) The function CONVERT() was made to format the date like you need, it is not parametric function, but you can use part of the result to format the result like you need:
select convert( char(8), getdate() , 8) -- part hh:mm:ss of actual datetime
select convert( varchar, getdate() , 112) -- yyyymmdd
select convert( char(10), getdate() , 20) -- yyyy-mm-dd limited by 10 characters
DATETIME cold be calculated in seconds and one interesting result mixing these four function is to show a formated difference um hours, minutes and seconds (hh:mm:ss) between two dates:
declare #date1 datetime, #date2 datetime
set #date1=DATEADD(s,-638,getdate())
set #date2=GETDATE()
select convert(char(8),dateadd(s,datediff(s,#date1,#date2),'1900-1-1'),8)
... the result is 00:10:38 (638s = 600s + 38s = 10 minutes and 38 seconds)
Another example:
select distinct convert(char(8),dateadd(s,datediff(s, CRDATE , GETDATE() ),'1900-1-1'),8) from sysobjects order by 1
I tried this way and it worked. I used SQL Server version 2016
SELECT DATEDIFF(MILLISECOND,'2010-01-22 15:29:55.090', '2010-01-22 15:30:09.153')/1000.00;
Different DATEDIFF Functions are:
SELECT DATEDIFF(year, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(quarter, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(month, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(dayofyear, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(day, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(week, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(hour, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(minute, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(second, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(millisecond, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');

Ok we all know the answer involves DATEDIFF(). But that gives you only half the result you may be after. What if you want to get the results in human-readable format, in terms of Minutes and Seconds between two DATETIME values?
The CONVERT(), DATEADD() and of course DATEDIFF() functions are perfect for a more easily readable result that your clients can use, instead of a number.
i.e.
CONVERT(varchar(5), DATEADD(minute, DATEDIFF(MINUTE, date1, date2), 0), 114)
This will give you something like:
HH:MM
If you want more precision, just increase the VARCHAR().
CONVERT(varchar(12), DATEADD(minute, DATEDIFF(MINUTE, date1, date2), 0), 114)
HH:MM.SS.MS
There are a number of ways to look at a date difference, and more when comparing date/times. Here's what I use to get the difference between two dates formatted as "HH:MM:SS":
ElapsedTime AS
RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
I used this for a calculated column, but you could trivially rewrite it as a UDF or query calculation. Note that this logic rounds down fractional seconds; 00:00.00 to 00:00.999 is considered zero seconds, and displayed as "00:00:00".
If you anticipate that periods may be more than a few days long, this code switches to D:HH:MM:SS format when needed:
ElapsedTime AS
CASE WHEN DATEDIFF(S, StartDate, EndDate) >= 359999
THEN
CAST(DATEDIFF(S, StartDate, EndDate) / 86400 AS VARCHAR(7)) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 86400 / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
ELSE
RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
END
The following query should give the exact stuff you are looking out for.
select datediff(second, '2010-01-22 15:29:55.090' , '2010-01-22 15:30:09.153')
Here is the link from MSDN for what all you can do with datediff function .
https://msdn.microsoft.com/en-us/library/ms189794.aspx
Internally in SQL Server dates are stored as 2 integers. The first integer is the number of days before or after the base date (1900/01/01). The second integer stores the number of clock ticks after midnight, each tick is 1/300 of a second.
More info here
Because of this, I often find the simplest way to compare dates is to simply substract them. This handles 90% of my use cases. E.g.,
select date1, date2, date2 - date1 as DifferenceInDays
from MyTable
...
When I need an answer in units other than days, I will use DateDiff.
SELECT DATEDIFF(yyyy, '2011/08/25', '2017/08/25') AS DateDiff
It's gives you difference between two dates in Year
Here (2017-2011)=6 as a result
Syntax:
DATEDIFF(interval, date1, date2)
Use This for DD:MM:SS:
SELECT CONVERT(VARCHAR(max), Datediff(dd, '2019-08-14 03:16:51.360',
'2019-08-15 05:45:37.610'))
+ ':'
+ CONVERT(CHAR(8), Dateadd(s, Datediff(s, '2019-08-14 03:16:51.360',
'2019-08-15 05:45:37.610'), '1900-1-1'), 8)
So this isn't my answer but I just found this while searching around online for a question like this as well. This guy set up a procedure to calculate hours, minutes and seconds. The link and the code:

PRINT DATEDIFF(second,'2010-01-22 15:29:55.090','2010-01-22 15:30:09.153')
select

result:

14.063
Just thought I'd mention it.
Sol-1:
select
StartTime
, EndTime
, CONVERT(NVARCHAR,(EndTime-StartTime), 108) as TimeDiff
from
[YourTable]
Sol-2:
select
StartTime
, EndTime
, DATEDIFF(hh, StartTime, EndTime)
, DATEDIFF(mi, StartTime, EndTime) % 60
from
[YourTable]
Sol-3:
select
DATEPART(hour,[EndTime]-[StartTime])
, DATEPART(minute,[EndTime]-[StartTime])
from
[YourTable]
Datepart works the best

For Me This worked Perfectly
Convert(varchar(8),DATEADD(SECOND,DATEDIFF(SECOND,LogInTime,LogOutTime),0),114)
and the Output is
HH:MM:SS which is shown accurately in my case.
Please try
DECLARE #articleDT DATETIME;
DECLARE #nowDate DATETIME;
-- Time of the ARTICLE created
SET #articleDT = '2012-04-01 08:10:16';
-- Simulation of NOW datetime
-- (in real world you would probably use GETDATE())
SET #nowDate = '2012-04-10 11:35:36';
-- Created 9 days ago.
SELECT 'Created ' + CAST(DATEDIFF(day, #articleDT, #nowDate) AS NVARCHAR(50)) + ' days ago.';
-- Created 1 weeks, 2 days, 3 hours, 25 minutes and 20 seconds ago.
SELECT 'Created '
+ CAST(DATEDIFF(second, #articleDT, #nowDate) / 60 / 60 / 24 / 7 AS NVARCHAR(50)) + ' weeks, '
+ CAST(DATEDIFF(second, #articleDT, #nowDate) / 60 / 60 / 24 % 7 AS NVARCHAR(50)) + ' days, '
+ CAST(DATEDIFF(second, #articleDT, #nowDate) / 60 / 60 % 24 AS NVARCHAR(50)) + ' hours, '
+ CAST(DATEDIFF(second, #articleDT, #nowDate) / 60 % 60 AS NVARCHAR(50)) + ' minutes and '
+ CAST(DATEDIFF(second, #articleDT, #nowDate) % 60 AS NVARCHAR(50)) + ' seconds ago.';
For MS SQL, you can convert the datetime value to a double value.
The integer part contains the number of days since 1900-01-01, the fractional part contains the time in hours.
So you can calculate date difference as:
cast(date1-date2 as FLOAT)
Given two date/times:
#start_date = '2009-04-15 10:24:00.000'
#end_date = '2009-04-16 19:43:01.000'
Is it possible to calculate the time elapsed between the two dates in the following format
1d 9h 19m
You can get the difference between the two dates to whatever resolution you want (in your example, minutes):
DATEDIFF(minute, #start_date, #end_date)
From there it's a simple matter of dividing minutes into hours and hours into days and modding the remainder.
I know this thread is older and the original participants are likely no longer watching, but I stumbled upon it, and had already written some code fairly recently to do something very close to what jdiaz is requesting. The result is rendered as a string in D:H:M:S format.
Step one would be to get the time span in seconds:
DECLARE #ElapsedS INT
SET #ElapsedS = DATEDIFF(second, #start_date, #end_date)
Now create the following scalar function:
CREATE FUNCTION [dbo].[udfTimeSpanFromSeconds]
(
#Seconds int
)
RETURNS varchar(15)
AS
BEGIN
DECLARE
--Variable to hold our result
#DHMS varchar(15)
--Integers for doing the math
, #Days int --Integer days
, #Hours int --Integer hours
, #Minutes int --Integer minutes
--Strings for providing the display
, #sDays varchar(5) --String days
, #sHours varchar(2) --String hours
, #sMinutes varchar(2) --String minutes
, #sSeconds varchar(2) --String seconds
--Get the values using modulos where appropriate
SET #Hours = #Seconds/3600
SET #Minutes = (#Seconds % 3600) /60
SET #Seconds = (#Seconds % 3600) % 60
--If we have 24 or more hours, split the #Hours value into days and hours
IF #Hours > 23
BEGIN
SET #Days = #Hours/24
SET #Hours = (#Hours % 24)
END
ELSE
BEGIN
SET #Days = 0
END
--Now render the whole thing as string values for display
SET #sDays = convert(varchar, #Days)
SET #sHours = RIGHT('0' + convert(varchar, #Hours), 2)
SET #sMinutes = RIGHT('0' + convert(varchar, #Minutes), 2)
SET #sSeconds = RIGHT('0' + convert(varchar, #Seconds), 2)
--Concatenate, concatenate, concatenate
SET #DHMS = #sDays + ':' + #sHours + ':' + #sMinutes + ':' + #sSeconds
RETURN #DHMS
END
Now feed your timespan into the newly created function:
SELECT TimeSpan = dbo.udfTimeSpanFromSeconds(#ElapsedS)
Should produce '1:09:19:01'
CONVERT(
varchar(8),
(
CAST(#end_date AS DATETIME)
-
CAST(#start_date AS DATETIME)
)
,108
)
This'll give it to you as HH:MM:SS

DATEDIFF can return unintuitive values. For example, the two dates below differ by one second yet DATEDIFF with the parameters below and interpreted as others have interpreted it above returns 1 year:
SELECT DATEDIFF(year, '2005-12-31 23:59:59', '2006-01-01 00:00:00')
Look at the MSDN documentation for DATEDIFF to understand how it works.
datediff(datepart, date1, date2);
Rex's answer is more complete.
Here's how you format the datediff (50d 8h 35m) in a query:
Declare #Date1 as Datetime, #Date2 as Datetime
Set #Date1 = '2005-01-01 08:00:00'
Set #Date2 = '2005-02-20 16:35:30'
Select
CAST(DATEDIFF(Minute,#Date1, #Date2)/60/24 as Varchar(50)) ++ 'd ' ++
CAST((DATEDIFF(Minute,#Date1, #Date2)/60)-((DATEDIFF(Minute,#Date1, #Date2)/60/24)*24) as Varchar(50)) ++ 'h ' ++
CAST((DATEDIFF(Minute,#Date1, #Date2)) - (DATEDIFF(HOUR,#Date1, #Date2)*60) as Varchar(50)) ++ 'm' as FormattedDateDiff
DECLARE #FirstDate DATETIME, #SecondDate DATETIME, #result VARCHAR(MAX)
SELECT #FirstDate = '2017-03-01 09:54:00.637', #SecondDate = GETDATE()
DECLARE #Day INT,#Month INT,#Hour INT, #Minute INT,#TotalSeconds INT,#Year INT
SELECT #TotalSeconds = ABS(DATEDIFF(SECOND,#FirstDate,#SecondDate))
-- Standard values in seconds
DECLARE #YearSeconds INT, #MonthSeconds INT, #DaySeconds INT, #HourSeconds INT, #MinuteSeconds INT
SELECT #MinuteSeconds = 60
SELECT #HourSeconds = 60 * #MinuteSeconds
SELECT #DaySeconds = 24 * #HourSeconds
SELECT #MonthSeconds = 30 * #DaySeconds
SELECT #YearSeconds = 12 * #MonthSeconds
--SELECT #MinuteSeconds AS [Minutes], #HourSeconds AS [Hours], #DaySeconds AS [Day],#MonthSeconds AS [Month],#YearSeconds AS [Year]
IF #TotalSeconds < #MinuteSeconds
BEGIN
SELECT #result = CAST(#TotalSeconds AS NVARCHAR(20)) + ' seconds ago'
END
ELSE IF #TotalSeconds < #HourSeconds
BEGIN
SELECT #result = CAST(ABS(DATEDIFF(MINUTE,#FirstDate,#SecondDate)) AS NVARCHAR(20)) + ' minutes ago'
END
ELSE IF #TotalSeconds < #DaySeconds
BEGIN
SELECT #result = CAST(ABS(DATEDIFF(HOUR,#FirstDate,#SecondDate)) AS NVARCHAR(20)) + ' hours ago'
END
ELSE IF #TotalSeconds < #MonthSeconds
BEGIN
SELECT #result = CAST(ABS(DATEDIFF(DAY,#FirstDate,#SecondDate)) AS NVARCHAR(20)) + ' days ago'
END
ELSE IF #TotalSeconds < #YearSeconds
BEGIN
SELECT #result = CAST(ABS(DATEDIFF(MONTH,#FirstDate,#SecondDate)) AS NVARCHAR(20)) + ' months ago'
END
