What do you mean by "latest row"?
Concepts like "latest", "earliest", "first", "next", etc. only have meaning when you are dealing with an ordered set of data. Since rows in a table in a relational database are inherently unordered, none of these concepts have any meaning.
Is there a column in your table which allows you to order the row data? For example, if you have a datetime column such as 'DateEntered', then you could easily find the row with the maximum value, and that would correspond to the 'latest' row.
