Removing and Manipulating Time portion from DateTime in SQLServer

One of the common transformation we would have to do as part of ETL would be manipulating Time portion. Please see some of below code, which would help to resolve some of the time related transformation

Case1 - Getting only Date portion from DateTime

/* Removing Time portion from DateTime */ 

Select
-- Standard date with time
 getdate() As DateWithTime,
-- Returns Date Portion Only

 dateadd(d, 0, datediff(d, 0, getdate())) As DateOnly


Result as below:















Case2 - /* Removing Seconds from DataTime */

/* Removing Seconds from DataTime */
declare @t datetime
set @T = GETDATE()
SELECT @T as Original
,DATEadd(ss,-datepart(ss,@t),@t) as wihtout_sec -- if no milisecs
,DATEADD(mi,DateDiff(mi,0,@t),0) as OneMore_Variation









Case3 - We want to Keep Hours but remove Minutes and Seconds from DateTime

/* Keep Hours but remove Minutes and Sec from DateTime */
select Dateadd( hh, DATEDIFF(hh,0,getdate()),0) AS DateWithHours_No_MinutesAndSeconds

Calculating Age of the person in T-SQL

One of common calculations, we have to do in ETL is calculating age of the person from the date attribute And this is how I have calculated Age of the person. Select BirthDate , CASE             WHEN Month ( GetDate ()) < Month ( c . [BirthDate] )                 THEN DateDiff ( yy , c . [BirthDate] , GetDate ()) - 1             WHEN Month ( GetDate ()) = Month ( c . [BirthDate] )             AND Day ( GetDate ()) < Day ( c . [BirthDate] )                 THEN DateDiff ( yy , c . [BirthDate] , GetDate ()) - 1             ELSE DateDiff ( yy , c . [BirthDate] , GetDate ())         END AS [Age]               from [dbo] . [DimCustomer] c               order by BirthDate I am sure, there would be other better ways to do this and would love to hear, of how you have calculated age of the person
