How to select a row based on its row number?

I'm working on a small project in which I'll need to select a record from a temporary table based on the actual row number of the record.

How can I select a record based on its row number?

Answer Source

A couple of the other answers touched on the problem, but this might explain. There really isn't an order implied in SQL (set theory). So to refer to the "fifth row" requires you to introduce the concept

Select *
      Row_Number() Over (Order By SomeField) As RowNum
    , *
    From TheTable
) t2
Where RowNum = 5

In the subquery, a row number is "created" by defining the order you expect. Now the outer query is able to pull the fifth entry out of that ordered set.
