You can also do it as:

SELECT DISTINCT TOP 2 Name, Age FROM YourTable

If you only want to eliminate duplicate records, you can use DISTINCT:

select distinct top 2 Name, Age

from YourTable

which returns:

A 17

B 14

But if you want to find two oldest people you have to return 3 records,
because B and C are the same age. In this case you can use WITH TIES:

select distinct top 2 with ties Name, Age

from YourTable

which returns:

A 17

C 16

D 16

The .."WITH TIES" statement you wrote wouldn't return the result you wrote.

In this case:

select distinct top 2 with ties Name, Age
from YourTable

WILL NOT RETURN

A 17
C 16
D 16

(also order by is required when you use WITH TIES )

I think WITH TIES return when (n+1), (n+2),..... rows are EXACTLY similar to
n(th) row (when you sepcify TOP n). Here in this case

2nd row ---> C 16
3rd row ---> D 16

aren't EXACTLY same.

Oops! Yes you are right, I forgot to add ORDER BY. Use this:

select distinct top 2 with ties Name, Age
from YourTable
order by Age

Now the result is:

A 17
C 16
D 16

In WITH TIES records need to have EXACTLY the same values for the fields
that are listed in ORDER BY clause, not all the fields. In this example C
and D have same value for Age.

Alexqa,

Try query in following example

--sample table / records

create table tb (name char(1), age int)
insert into tb
select 'A', 17 union all
select 'A', 17 union all
select 'B', 14 union all
select 'C', 16 union all
select 'D', 16

--query
select name,age from
(select name,age,
(select count(distinct age) from tb b
where a.age <= b.age) rank
from tb a) X
where rank <= 2
--
-Vishal

Your query gives the following output:

name age
---- -----------
A 17
A 17
C 16
D 16

But this is not what Alexqa want.
