Dear Sir, This is not that soluation, which I needs.. Ex: If an employee joined a company on "2016-06-19" and today date is "2020-04-15". So I need total experience of that employee. 2020-04-15 - 2016-06-19 = 3 years 9 months 26 days Thanks in advance.

Let us consider start date and end date from the table. The DATEDIFF() helps to find the exact number of days, months and year between two different dates. SELECT CAST (DATEDIFF(yy, t.StartDate, t.EndDate) AS varchar (4)) + ' year ' + CAST (DATEDIFF(mm, DATEADD(yy, DATEDIFF(yy, t.StartDate, t.EndDate), t.StartDate), t.EndDate) AS varchar (2)) + ' month ' + CAST (DATEDIFF(dd, DATEADD(mm, DATEDIFF(mm, DATEADD(yy, DATEDIFF(yy, t.StartDate, t.EndDate), t.StartDate), t.EndDate), DATEADD(yy, DATEDIFF(yy, t.StartDate, t.EndDate), t.StartDate)), t.EndDate) AS varchar (2)) + ' day' AS result FROM table_3 t Final Output will be

Dear Ankit, I have this code to get difference in hh:mm:ss. Can you try to modify as per your requirment. Please find below code declare @StartDate datetime, @EndDate datetime select @StartDate = '10/01/2020' ,@EndDate= '10/04/2020' select convert ( varchar (5),DateDiff(s, @startDate, @EndDate)/3600)+ ':' + convert ( varchar (5), DateDiff(s, @startDate, @EndDate)%3600/60)+ ':' + convert ( varchar (5),(DateDiff(s, @startDate, @EndDate)%60)) as [hh:mm:ss] Please let me know if you require more help.

Hey Ankit, If you want existing date in "dd/mm/yyyy" . You can try below code SELECT CONVERT ( varchar , getdate(), 103) //Response I got 20/06/2020 In place of getDate(), pass ur column value.Here style 103 is dd/mm/yyyy format. If you want to calculate the difference you may need to write some store procedure or function to retrive the date in dd/mm/yyyy format.

You have to query in the format of yyyy/MM/dd and if your datatype is some else than date or datetime then change it to date format
