How to find all attributes in a database which contain NULL? -- (not a count of all NULLs, just the attribute names are wanted)

In other words, those which are not merely nullable, but have a NULL "value"

So not merely:


SELECT name as [column_name] 
FROM sys.all_columns
where is_nullable = 1

You can play around with this:
select 'select count(*) as ' + column_name + ' from ' + table_name
from information_schema.columns
where is_nullable = 'YES'
