Could try the below, not sure if it works in SQL though.
Expand|Select|Wrap|Line Numbers
  1. SELECT MAX(column) FROM tablename

Correct me if i'm wrong, but do you mean last row entered into a table?
Expand|Select|Wrap|Line Numbers
  1. SELECT MAX(MySequentialIndexColumn) from [MyTable]
works based on the premise that MySequentialIndexColumn is an IDENTITY column continuously incremented with each addition to the table. Therefore, the highest value of the column should be the latest entry.

Here's my advice:

If it is important to know when a row was added to a table the time/date of insertion should be listed as a field. With the addition of a time/date field, you will be able to query your table based on the exact time rows were entered.

If you have an identity column then u could use

Expand|Select|Wrap|Line Numbers
  1. select @@Identity from myTable

select @@Identity from myTable

if u have and identity column which set ur rows in order 1 2 3 4 5 etc
then it will pull the last value inserted in the database.

i add a index column like so

Expand|Select|Wrap|Line Numbers
  1. alter table MYTable
  2. Add TempID int IDENTITY(1,1)
