Hi Saroj13,

The order by would be applied to each SQL prior to the except - after the except the order can be different.  To get the order you want you should do an order by on the result , i.e. SELECT * FROM (your query) as v ORDER BY DateStamp asc.  In this case the ORDER BY in your top SQL may be unnecessary.

Hi lwadwell:,

I need order by in both the queries.

What I want is . I want all the data according to date.
Then i want top 15 from this all data. Then I want to subtract it.

Saroj13,

I understand that you need the ORDER BY for the TOP 15 ... that is fine.  The EXCEPT returns those rows from the top query not returned from the bottom query - it does not need the top query to be sorted (it will do that itself).  I was suggesting:

SELECT * FROM (
select * from Links
except
select top 15 * from Links order by DateStamp asc
) as v ORDER BY DateStamp asc

There are various ways of doing this. You can try appari post. You can also try like this.
SELECT *
  FROM Links
 WHERE NOT EXISTS (SELECT TOP 15 * FROM Links ORDER BY DateStamp DESC)
 
Or like this
SELECT *
  FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY DateStamp DESC) AS RN FROM Links) T1
 WHERE T1.RN > 16

this would do also:
select * from Links 
where primary_key_field not in (  select top 15 primary_key_field from Links order by DateStamp asc )
order by DateStamp asc

I just stumbed upon something while trying to fix a similar problem.  You can order by SQL's name for this field.  In my case I had, SELECT field1 AS field1, field2 AS field2...Except...

I ordered by 00004 (the 4th field) at the end of the statement.

I hope this helps someone
