i would like to update my stored procedure, which is ran daily, to only enter current day and 1 day prior. The tsql is doing joins on 4 tables i would like to get the previous days entries along with the current day it is being loaded on a column labled last_update_date.

i have something like this last_update_date >= dateadd(day,datediff(day,1,GETDATE()),0)

however it is still pulling all the historical days which i dont want, because it will create duplicate rows. if the day already exist it should skip over it and only enter current day -1(previous).

[code]last_update_date >= dateadd(day,datediff(day,1,GETDATE()),0)[/code]
that condition will only give you records where last_update_date that is greater than yesterday's date.

the last update date is the last day the record was updated so if it is currently 2014-02-28 00:00:00:000 it should look back to 2014-02-27 00:00:00:000 and 2014-02-28 00:00:00:000

USE Tempdb;
GO

SET NOCOUNT ON;

IF OBJECT_ID ('#CustomerA', 'U') IS NOT NULL
DROP TABLE #CustomerA;
SELECT 1 as ID ,
CAST('28/02/2014' as DATE) as TranDate
INTO #CustomerA;

INSERT INTO #CustomerA
SELECT 2 as ID ,
CAST('27/02/2014' as DATE) as TranDate;

INSERT INTO #CustomerA
SELECT 3 as ID ,
CAST('26/02/2014' as DATE) as TranDate;
GO

SELECT *
FROM #CustomerA as A
WHERE TranDate >= CAST((GETDATE() -1) as DATE)

What do you want for output?

If you can describe in words what you want to happen it makes it, potentially, easier to understand than code that doesn't work/give the proper results.
