How to use SQL(Max) function

I have 2 tables

Table 1:

id     name      adress 
1      John      New York
2      Jane      London`

... and so on

Table 2:

id    fila      date
1     43        01/01/2010
1     39        10/01/2011
1     55        23/12/2012
2     10        01/01/2008
2     15        02/02/2010`

.... and so on

I want to get data like this

id  fila   name     adress       date
-----------------------------------------
1   55     John    New York    23/12/2012
2   15     Jane    London      02/02/2010

..... and so on.

Thanks

ok. what you are really looking for is "What is the latest date in table2 for each of my rows in Table1". So to answer the question:

select *
From Table1
inner join (
    select id, max(fila) as maxfila
    from Table2
    group by id
) as maxdates
on Table1.id = maxdates.id
inner join Table2 on Table2.id = maxdates.id AND Table2.fila = maxdates.maxfila

select t1.id, t1.name t1.address, max(t2.fila), 
(select top 1 date from table2 order by fila desc where table2.id = t1.id)
 from table1 t1 inner join 
 table2 t2 on t1.id = t2.id

Try this

Select t1.id, t1.name, t1.address, t2.maxfila
 from table1 t1 
  left outer join 
  (select id, max(fila) maxfila
  from table2
  group by id) t2

Try this:

;with cte as
 (select id, max(fila) maxfila
  from table2
  group by id)
 select t1.id, t1.name, t1.address, t2.fila, t2.date
 from table1 t1 
 left join table2 t2 on t1.id = t2.id
 inner join cte c on t1.id = c.id
 where t2.fila = c.maxfila
