Inserting data in composite types

  Hi, I have a question about how to insert data in composite types!

  Imagine the exemple:

CREATE TYPE t_time AS (

  a date,

  b date

);

CREATE TABLE salary (

   salary numeric(10,2),

   t_date t_time

);

I know that if I want to insert data in the table SALARY I just have to do like:

  INSERT INTO salary VALUES (1000.00, ‘(2006/10/10, 2006/12/10)’);

But if I have another table:

CREATE TABLE employee (

  employee_id int,

  name varchar(30),

  emp_salary salary

)

How can I insert a single row in this table???

Thanks in advamce!
