Nice post and tricky. below is the only solution I could come up with.

CREATE TABLE #temp
(name VARCHAR(100),registered smalldatetime)
GO
DECLARE @test smalldatetime
SET @test=GETDATE()
INSERT INTO #temp
VALUES (‘Value1′,@test)
INSERT INTO #temp
VALUES (‘Value0′,@test)
INSERT INTO #temp
VALUES (‘Value2′,@test)
GO
;With CTE AS (
Select name, registered, ROW_NUMBER() OVER(ORDER BY registered DESC) AS RowNumber
From #temp)
SELECT name, registered
FROM CTE a
ORDER BY RowNumber Desc
GO
DROP TABLE #temp
GO

Yesterday Raghavendra called me and asked this question. My initial thought was also to make schema changes but the requirement is without making schema changes how can you do this. He was telling the database is in SQL Server 2000. I couldn’t find any solution without making any schema changes.

Raghavendra you will still end up on the same situation.

Just try to create the index – which I demonstrated in my blog post on it and you will get incorrect Identity solution.

I think I see no solution without Schema change.

SmallDatetime converts seconds value to its nearest Minute value. As a Result seconds value is always 0. Without changing the schema, i don’t think this will be shown as required output.

Hi Pinal,

Thanks for posting.. how abt below solution?

create table #temp
(
name varchar(100),
registered smalldatetime
)

declare @test smalldatetime
set @test=getdate()

insert into #temp
values (‘Raghav1′,@test)

insert into #temp
values (‘Raghav2′,@test)

Select IDENTITY(int,1,1) AS [Row Number]
, name,registered
INTO #Temp2
from #temp
– [edited]

SELECT *
FROM #Temp2 order by registered desc,[Row Number] Desc

Regards,
Raghavendra SK

Point to be noted is that there is no guarantee with this solution and that is why I have written that NOT solution.

if primary key is created at the time of creating table then result is again same.

CREATE TABLE #temp
(name VARCHAR(100) NOT NULL primary key,registered smalldatetime)
GO

Why ?
