SQL

CREATE TABLE #Test
(
	DisplayOrder int,
	PostedDate date,
	ImageName nvarchar(50)
)

declare @DateToSelect datetime

set @DateToSelect = '9/1/2013'

--Uncomment this line to see it working for the 10th.
--set @DateToSelect = '10/1/2013'

insert into #Test values (1, '9/1/2013', 'Img1')
insert into #Test values (2, '9/1/2013', 'Img1')
insert into #Test values (2, '10/1/2013', 'Img1New')
insert into #Test values (3, '9/1/2013', 'Img1')

select 
	#Test.DisplayOrder, 
	#Test.PostedDate, 
	#Test.ImageName 
from 
	#Test
join
(
	select
	displayOrder, 
	Max(PostedDate) as 'PostedDate'
	from
	#Test
	where PostedDate <= @DateToSelect
	group by displayOrder
) as SQ on (SQ.DisplayOrder = #Test.DisplayOrder) AND (SQ.PostedDate = #Test.PostedDate)


DROP TABLE #Test

my five to you.

that's the way to have the posted name "linked" to the max posteddate.

Solution 1

SQL

SELECT Displayorder ,max(PostedDate) as PostedDate ,ImageName FROM MyTable WHERE PostedDate < SYSDATE GROUP BY DisplayOrder ,ImageName

SYSDATE is Oracle specific, exchange it to whatever is appropriate in your database.
Ignore my solution, it's incorrect, use Francois Viljoens or Aarti Meswanias instead.

This way...

SQL

select * from
(
select row_Number() over(partition by DispalyOrder order by PostedDate desc) as Id, DispalyOrder,ImageName,PostedDate from a
where PostedDate <='2013-01-11'
) as a
where Id=1

Happy Coding!
