Subject: Simple SQL Query


I have a simple SQL query which lists all the records that are not in a
second table.

select first.id from first
where first.id not in (select id from second);

As the second table is very huge, it takes a very long to process the
query.
Is there a way to rewrite the query to run it quicker?
