I had admittedly slightly misunderstood the request of this post, there is clearly a different between field layouts and specific fields.
Still, if you do want to find subfields of a field in a field group try..
SELECT *
FROM wpas_postmeta pm, wpas_posts p
WHERE pm.meta_value LIKE "%paragraph_with_large_image%"
AND pm.post_id = p.ID
AND p.post_status = "publish"
