Answer 1

Try using Row_number() with Partition

;with cte as
(
select I.Uid, I.ImagePath,rn=row_number()over(partition by I.Uid order by u.Date desc), I.status from user u inner join Image I on u.Uid=I.Uid
)

select * from cte where rn=1

Answer 2

You do not need to do the join but instead can find the distinct UID in image table.

select distinct I.Uid from Image I;

Or if you want to list the specific columns distinctly:

select distinct I.Uid, I.ImagePath, I.status from Image I order by u.Date desc;
