try this you can access last N rows :
select top N ( select * from tablename1 order by id desc ) from tablename1
select top N ( select * from tablename1 order by id desc ) from tablename1
What is the structure of the table? Are there any fields with date or timestamp that would determine when the rows were entered? If not, what criteria would you use to determine "last"?
from table-name
ORDER BY Timestamp or Identity column DESC
here you can use either timestamp column or if the column has an identity column then can use it
