[erlang-questions] Mnesia equivalent of SQL NOT IN

I have two records:

-record(foo, {timestamp, name}).  -record(bar, {timestamp, name}).  

And I would like to execute a Mnesia query that mimics the following SQL query

SELECT f.* FROM foo f WHERE f.timestamp NOT IN ( SELECT b.timestamp FROM boo b)  

What would be an efficient Mnesia equivalent?
