Delete Top-N' Rows from a Table with some sorting(order by 'Column')

Question

I am having some confusion regarding Deleting the top N Rows order by some column.

I created have an example here Example at fiddle

What is wrong with these

Answer 1

Add the top 3 clause to the subselect:

Delete from Table1 
where id IN (
    select top 3 id 
    from Table1 
    order by id desc
)

Answer 2

You can use a CTE to do a faster ordered delete without the need for a separate sub query to retrieve the top 3 ids.

WITH T
     AS (SELECT TOP 3 *
         FROM   Table1
         ORDER  BY id DESC)
DELETE FROM T
