Using IN with two columns

Question

Hi all,
I have to perform a query like x,y not in(select x,y from k). How to do this. These two columns are composite primary keys in both tables although no references exists.
A sample table and expected result.
create table v(name varchar(10),place varchar2(10));
create table t(name varchar(10),place varchar2(10));
insert into t values('Antony','Ollur');
insert into t values('Paul','Ollur');
insert into v values('Antony','Ollur');
I need to select second row from table t which does not exist in v.
Expected result
Paul Ollur
Thanks in advance.
Antony Paul

There are a number of ways to do this:
SELECT * FROM t
WHERE (name, place) NOT IN
   (SELECT v.name, v.place FROM v)
SELECT * FROM t
WHERE  NOT EXISTS
   (SELECT null FROM v
    WHERE  v.name = t.name
    AND    v.place = t.place )
SELECT t.name, t.place  FROM t, v
WHERE  v.name(+) = t.name
AND    v.place(+) = t.place
AND    v.name IS NULL
SELECT t.name, t.place  FROM t, v
WHERE  v.name != t.name
OR     v.place != t.place
/The AND version of this last query doesn't work because both rows in T match a row in V on the basis of PLACE.
