There is no such thing as the "last record of a table" in SQL. Somehow
you must be able to describe what you mean with "last record" and how to
identify that. This would then be translated into a qualification (WHERE
clause) and is the answer to your question.

Select * from <tablename> where <...> desc limit 1;
Desc = from the bottom up, limit 1 = just one record.
Best regards,
Chris
