For all the rows in the database
     if row has no null values

Answer 1

This is the opposite of this question Test if any fields are NULL.

The answer by Martin Smith modified to find rows without null values would look like this.

;with xmlnamespaces('http://www.w3.org/2001/XMLSchema-instance' as ns)
select *
from YourTable as T
where
  (
    select T.*
    for xml path('row'), elements xsinil, type 
  ).exist('//*/@ns:nil') = 0

And the answer provided by Aaron Bertrand modified would be…

DECLARE @tb NVARCHAR(255) = N'YourTable';

DECLARE @sql NVARCHAR(MAX) = N'SELECT * FROM ' + @tb
    + ' WHERE 1 = 1';

SELECT @sql += N' AND ' + QUOTENAME(name) + ' IS NOT NULL'
    FROM sys.columns 
    WHERE [object_id] = OBJECT_ID(@tb);

EXEC sp_executesql @sql;
