Hi sb92075 ,
i got it i am trying to see how can i tweak it lit bit..
in my case i have a cross tab query were values in my SELECT statment are different , example :
SELECT *
FROM
SELECT
PROJECTNAME,
PROJECTID
SUM(DECODE(to_char(IM_MONTH,'mm-yyyy'), to_char(add_months(sysdate,1),'mm-yyyy'), SALE,0)) as '01-2011'
,SUM(DECODE(to_char(IM_MONTH,'mm-yyyy'), to_char(add_months(sysdate,2),'mm-yyyy'), SALE,0)) as '02-2011'
,SUM(DECODE(to_char(IM_MONTH,'mm-yyyy'), to_char(add_months(sysdate,3),'mm-yyyy'), SALE,0)) as '03-2011'
FROM TABLE
what i am looking for is :
1-
to have (sysdate,1) replaced by the 1st month of the current year 'JAN-2011'
same thing for (sysdate,2) replaced by the 1st month of the current year 'FEB-2011'
and so on until the last month of the next year . In total 24 monthss
2-
for each select item , i need to have the column called by that month name i.e :
SUM(DECODE(to_char(IM_MONTH,'mm-yyyy'), to_char(add_months(month1),'mm-yyyy'), SALE,0)) as 'month1'
SUM(DECODE(to_char(IM_MONTH,'mm-yyyy'), to_char(add_months(month2),'mm-yyyy'), SALE,0)) as 'month2'
any thoughts ?
