Even if you don’t really need any aggregation, that is, when what you see in the table is what you’ll get in the result set, you still have to use an aggregate function. If there will only be one value contrinuting to each cell, then you can use MIN or MAX.

Does pivot require an aggregate?
Your initial question is whether you can PIVOT without aggregation. The answer is no: PIVOT requires aggregation. That being said – you can use pivot to get what you want, assuming you “pivot” smartly. The trick is to make sure that the pivoting occurs on a group that would only return one row.
Can you pivot in SQL?
