join question - three tables, two with foreign keys to the first

hey all,

here's my situation. three tables:

create table employee (id integer primary key, name varchar(32));
create table employee_leave (id integer primary key, employee_id integer,
from_date date, to_date date, constraint emp_leave_fk foreign key
(employee_id) references employee (id));
create table employee_pay (id integer primary key, employee_id integer,
amount integer, constraint emp_pay_fk foreign key (employee_id) references
employee (id));

and some sample data:

insert into employee (id, name) values (1, 'dim');
insert into employee_leave (id, employee_id, from_date, to_date) values (2,
1, '10-05-2002', '14-05-2002');
insert into employee_leave (id, employee_id, from_date, to_date) values (1,
1, '10-06-2002', '14-06-2002');
insert into employee_pay(id, employee_id, amount) values (1, 1, 100);
insert into employee_pay(id, employee_id, amount) values (2, 1, 100);

and I want to retrieve the information for an employee (all pay, and all
leave) in one query.... here's what I've got

select emp.name, lv.from_date, lv.to_date, pay.amount
from employee as emp
left outer join employee_leave as lv on emp.id = lv.employee_id
left outer join employee_pay as pay on emp.id = pay.employee_id
where emp.id = 1

problem is that I dont get the null values I expect.... I want to be able to
iterate through the resultset and determine if the record is from the leave
table or pay table - but because I dont get null results, I cant....

any pointers/suggestions would be welcome.

cheers
