Getting the last entry of a user from a MySQL table ordered by DateTime

Question

I have a table who looks something like this:

USERNAME    DATA   DATETIME
Jhon        text1  2010-06-01 16:29:43
Mike        text2  2010-06-01 16:29:22
Silver            


        

Answer 1

SELECT data FROM table WHERE username = 'Jhon' ORDER BY datetime DESC LIMIT 1

The "order by datetime desc" paired with "limit 1" gets you his last entry.
