  I have a table that has the following field

  [LOGDATETIMESTAMP] [datetime] NULL ,

  which basically contains the date and time that the row was inserted

  I want to return all of values where the datetimeStamp is = to the current day.

  Is this possible using the getDate Function. I dont want to hard code the day as this will be used by a stored procedure

  Where LOGDATETIMESTAMP>=dateadd(day,datediff(day,0,getdate()),0) and LOGDATETIMESTAMP<dateadd(day,datediff(day,0,getdate()),1)

  Hi mpeters

  Here's the theory:

  Get the current datetime using getdate()

  Strip off the time component, which gives today

  Add a day to the result, which gives tomorrow with no time component:

  [font="Courier New"]DECLARE @Today DATETIME, @Tomorrow DATETIME

  SET @Today = DATEADD(dd,DATEDIFF(dd, 0, GETDATE()), 0) -- '2008-09-23 00:00:00.000'

  SET @Tomorrow = DATEADD(dd,1,@Today) -- '2008-09-24 00:00:00.000'

  SELECT @Today, @Tomorrow -- Check the results

  SELECT *

  FROM yourtable

  WHERE [LOGDATETIMESTAMP] >= @Today AND [LOGDATETIMESTAMP] < @Tomorrow[/font]

  Cheers

  Awesome, thank for all the help guys, thought there might have been a function that made it a bit easier
