Thank you, Jeremy! It did worked.
One last question. About migrations. I have a few foreign keys already
declared and they are set to "on delete SET NULL". I would like to change
them to "on delete CASCADE". I know there was a way of doing this but
alter_table seems not mentioned about this.

Hi Jeremy,
I dig into querying.md and can't find any example about "NOT EXISTS".
How can we write this query in Sequel:
select * from books where not exists (select * from writers where .)
Thanks,
Gencer.
