Answer : T-SQL for last date

In my point of view, matthewspatrick solution is correct. if a customer has more thane one record with the maximum date, all those records have to be displayed.
Unless there is rewuirement that pick the max or min id record if more than one record present for the max date.
The asker can try like this also. Choose row_number or dense_rank depending on your requirement and the column names in order by clause.

1: 2: 3:

select * from (select *,dense_rank() over ( partition by Customer order by Date desc) as RN from #tst ) as t1 where t1.RN = 1
