Hi,
select * from x2;
INO NAME
13 PQR
11 ABC
11 DEF
12 JKL
12 MNO
11 GHI
select p.ino as ITEMNO,
       substr(max(substr(sys_connect_by_path (p.name,';'),2)),1,60) as ITEMNAME
from (select ino,name,
      row_number()over (partition by ino order by ino, name) rn
from x2) p
start with p.rn = 1
connect by p.rn = prior p.rn + 1
and prior p.ino = p.ino
group by ino;
