Mysql select UNIQUE row on column

Question

I have a table as following:(Ex)

id   | vid | time
------------------------
1    |  4  | 1333635317
2    |  4  | 1333635323
3    |  2  | 1333635336
4    |  4  | 1333635343
5    |  5  | 1333635349

I want to be just a row (the last row [ID: 4]) of the same rows [id:1,2,4] , how it will output the query?

I mean, as a result of these:

id   | vid | time
------------------------
3    |  2  | 1333635336
4    |  4  | 1333635343
5    |  5  | 1333635349

What do i do?

i trying it as:

SELECT * from tbale as t1 where vid = 4 GROUP BY vid ORDER BY id DESC

but doesn't work ORDER BY in my query.

Answer 1

Get the max time per vid and use in to get those rows from the table.

select * from tablename
where (vid,time) in (select vid,max(time) 
                     from tablename 
                     group by vid)
order by id
