I'm struggling with your English a bit as well (good effort, though
) so I'm not sure this is the answer you want but I think you're after this:-
Code:
Select ID, Max(Date), Name
From
(Select ID, Date, Name From Table1
Union
Select ID, Date, Name From Table2)
Group By ID, Name
The inner query 'combines' the two tables as HoneyBee suggested. The outer takes that combined table and returns you the highest date for each ID and Name combination.
