SELECT goodid,

SUM(decode(to_char(saledate,'mm'),'02',salesum)) "02",

SUM(decode(to_char(saledate,'mm'),'03',salesum)) "03",

SUM(decode(to_char(saledate,'mm'),'04',salesum)) "04",

SUM(decode(to_char(saledate,'mm'),'05',salesum)) "05",

SUM(decode(to_char(saledate,'mm'),'06',salesum)) "06",

SUM(decode(to_char(saledate,'mm'),'07',salesum)) "07",

SUM(decode(to_char(saledate,'mm'),'08',salesum)) "08",

SUM(decode(to_char(saledate,'mm'),'09',salesum)) "09",

SUM(decode(to_char(saledate,'mm'),'10',salesum)) "10",

SUM(decode(to_char(saledate,'mm'),'11',salesum)) "11",

SUM(decode(to_char(saledate,'mm'),'12',salesum)) "12"

from t1

where to_char(saledate,'yyyy') = '2004'
