Oct 27, 2012 TSQL Rounding or Truncating DateTime to Nearest Day, Hour, Minute or Second Posted on October 27, 2012 by SteveStedman Posted in TSQL — 7 Comments ↓ One thing that I end up having to look search on regularly is rounding of dates and times in Transact SQL, having looked this up too many times I finally realized that it is time for me to do. Let’s imagine we need to do the same thing but this time round to the nearest hour: Example Difference: 3645 seconds = 1 hour and 45 seconds ( we expect this to return 2 hours) 3646 / (60mins. 60secs) = 1.0125 CEIL(3646 / (60mins. 60secs)) = 2 2. (60mins. 60secs) = 7200 7200 seconds = 02:00:00.
I need a formula that will round times down to the nearest half hour. If time is 8:02 it should be 8:00.

If time is 8:23 it still should be 8:00.Also I need to add 3 hours to each of these times to compensate for the time difference between Eastern and Pacific standard.Can anyone help?Hi Junebug:Here is one way.

Hello:I've searched quite a bit and found a few solutions but not anything solid that currently works. This is how to diassemble the date time - assume datecol is a datetime columndatepart (arg, datecol) will return a part of a date according to argDatepart Abbreviationsto get the year use yy or yyyyto get the month use mm or mto get the day use dd or dto get the hour use hhto get the minute use mi or nto get the second use ss or sin order to assemble the date back, you just use the same function, and concat, for exampleselect cast( char(years)+'.' +char(month s)+'.' +cha r(days) etc. As datetime)the format depends on the format of dates that you usethis format is always acceptableyyyymmddalso consider using the dateadd function. Hi, try this functionTo use the function:select dbo.roundtime('13:15',0.5)The 1st param is the time to be rounded and the 2nd will be base on your list (0.5-half hour, 1-one hour.)CREATE function dbo.RoundTime (@Time datetime, @RoundTo float) returns datetime as begin declare @RoundedTime smalldatetime declare @Multiplier float set @Multiplier= 24.0/@RoundTo set @RoundedTime= ROUND(cast(cast(convert(varchar,@Time,114) as datetime) as float).
@Multiplier,0)/@Multiplier return @RoundedTime endSelect all.
