Very strange data and requirement...
With the data shown above, following query works:
SQL
SELECT Table1.ID,  Max(Table2.Amt)
FROM Table1, Table2
where table1.id>=table2.id and table1.id<=7
group by table1.id

[Edit]
The maximum value of table2 need not be hard coded but can be retrieved via a subquery:
SQL
SELECT Table1.ID,  Max(Table2.Amt)
FROM Table1, Table2
where table1.id>=table2.id and table1.id<= (select max(table2.id) from table2)
group by table1.id

[/Edit]

Good one
SQL
select a.id,case when a.id between 1 and 4 then 10 when a.id between  5 and 6 then 20 when a.id between 7 and 10 then 100 end  From table1 as a left join table2 as b on a.id=b.id

In this Query values are hard coded. need a dynamic query
Join Query :
SQL
SELECT t2.ID, t2.Amt
FROM Table1 t1, Tabele2 t2
WHERE t1.ID = t2.ID

I have seen such cases where "no repeatation" of data is needed. The result you need is simply depends upon the data but query.
Any way, can you tell me why are you doing this ?
