Subquery seem to fail though accepted by sqlite3.

[lcaballero]

Hi, I think this is a bug, but I'm not terribly familiar with this library and sql derivative.

This sql query:

SELECT
  count(),
  'user without role',
  id
FROM
  user as u
WHERE
  u.id
NOT IN (
  SELECT user_id
  FROM mm_user_access_role
)
;

But produces this error:

err: 11:3: expected expression, found 'SELECT'
