This one shows it is not solved:

select
ref_0.depend_type as c0,
ref_0.id as c1,
(select name from sys.objects)
as c2,
ref_0.depend_type as c3
from
sys.dependencies as ref_0
where (true)

,
ref_0.depend_id) as int) is not NULL)
or (ref_0.depend_type is NULL))
or (ref_0.depend_type is NULL))
limit 114;
