How to read the last row with SQL Server

Question

What is the most efficient way to read the last row with SQL Server?

The table is indexed on a unique key -- the \"bottom\" key values represent the last row.

Answer 1

I think below query will work for SQL Server with maximum performance without any sortable column

SELECT * FROM table 
WHERE ID not in (SELECT TOP (SELECT COUNT(1)-1 
                             FROM table) 
                        ID 
                 FROM table)

Hope you have understood it... :)
