Answer 1

You could use row_number():

select shop_id, 
  shop_name,
  shop_address
from
(
  select t1.shop_id,
    t1.shop_name,
    t2.shop_address,
    row_number() over(partition by t1.shop_id
                      order by t1.shop_name, t2.shop_address) rn
  from table_1 t1
  inner join table_2 t2
    on t1.shop_id = t2.shop_id
) src
where rn = 1

See a demo on SQL Fiddle

You can also use an aggregate function:

select t1.shop_id, 
  t1.shop_name,
  max(t2.shop_address) shop_address
from Table1 t1
inner join table2 t2
  on t1.shop_id = t2.shop_id
group by t1.shop_id, t1.shop_name
