As always:
- you don't post formatted
- you don't post the corresponding test case (who knows what you have in your tables?)
- you don't search
- you don't post in the correct forum, you are a newbie post in newbie forum

Regards
Michel

Hi,

Sample Pivot for you.

SQL> select deptno,sal from emp order by deptno;
   DEPTNO       SAL
--------- ---------
       10      2450
       10      5000
       10      1300
       20       800
       20      1100
       20      3000
       20      3000
       20      2975
       30      1600
       30      2850
       30      1250
       30       950
       30      1500
       30      1250


SQL> select deptno,
     max(decode(r,1,sal)) "SAL1",
     max(decode(r,2,sal)) "SAL2"
     from
    (select deptno,sal,
     row_number() over (partition by deptno order by deptno) r
     from emp)
     group by deptno
/
   DEPTNO      SAL1      SAL2
--------- --------- ---------
       10      2450      5000
       20       800      1100
