get null data?

[flamenco]

Hi:

I'm using access.
Suppose the next table "birthdays"

birthdays
--------------------------
name birthday
--------------------------
john 25/03/1984
gabriel
diana 08/02/1983

I want to make a query that returns "name" where "birthday" does not have value.

I tried this query:

SELECT name
FROM birthdays
WHERE birthday=null

the query does not return any name

How can I make the query?

Thanks!!
