Display rows into columns in table

Question

Hi,
I have a table name Ebiz_Upgrade_Task_Status. Here in table there are 8 rows of data with
pro_id,pobj_id,cemli_id and confirmation.
I am trying to convert all the CONFIRMATION into column wise using the query below
SELECT
PRO_ID,
POBJ_ID,
CEMLI_ID,
max(decode(rownum,1,CONFIRMATION,null)) "CP1",
max(decode(rownum,2,CONFIRMATION,null)) "CP2",
max(decode(rownum,3,CONFIRMATION,null)) "CP3",
max(decode(rownum,4,CONFIRMATION,null)) "CP4"
FROM Ebiz_Upgrade_Task_Status
GROUP BY PRO_ID,POBJ_ID,CEMLI_ID
Am able to see first 2 rows of data as columns, and not able to see the next rows. Please suggest me in modifyin the query

Thanks for posting more details.
Using rownum caused your confirmation fields to be null:
SQL> select * from temp1;
   PRO_ID   POBJ_ID  CEMLI_ID CONFIRMATION
      111       222       333 yes
      111       222       333 no
      111       222       333 na
       11        22        33 na
       11        22        33 no
       11        22        33 yes
