Answer 1

Use row_number() function

select *,
       row_number() over (partition by NoUrut order by NoUrut) as Rownum 
from table t;

Answer 2

Try this solution:

SELECT row_number() over (partition by NoUrut order by (SELECT 0)) as Rownum,
       NoUrut,Nama
FROM Table1;

OUTPUT:

Rownum  NoUrut  Nama
1        1      PSX
2        1      GE
3        1      SX
1        2      SZ
2        2      GEX
3        2      HT

Since You don't want to give order by on any column so use SELECT 0 in order by clause to accomplish the above result.
