Oracle中使用decode进行数据的列转换为行的试验

如何将以下数据格式的数据转换为
初始化格式如下：
1    市政府    房产    1    2    3
2    省政府    房产    4    3    4-
 

3    肥东    房产    5    4    5
4    肥西    房产    6    5    7
5    长风    房产    7    7    8
6    淮南    房产    8    9    5
7    市政府    汽车    1    2    3
8    省政府    汽车    4    3    4
9    肥东    汽车    5    4    5
10    肥西    汽车    6    5    7
11    长风    汽车    7    7    8
12    淮南    汽车    8    9    5
13    肥西    奢侈品    6    5    7
14    长风    奢侈品    7    7    8
15    淮南    奢侈品    8    9    5
16    市政府    贵重首饰    1    2    3
17    省政府    贵重首饰    4    3    4
18    肥东    贵重首饰    5    4    5

需要转变为

                        房产                    汽车                    奢侈品                    奢侈品       
       PRO_TYPE    场次    销售价    佣金    场次    销售价    佣金    场次    销售价    佣金    场次    销售价    佣金
1    淮南        8        9        5        8        9        5        8        9        5           
2    肥东        5        4        5        5        4        5                                5        4        5
3    市政府        1        2        3        1        2        3                                1        2        3
4    省政府        4        3        4        4        3        4                                4        3        4
5    肥西        6        5        7        6        5        7        6        5        7           
6    长风        7        7        8        7        7        8        7        7        8           

处理sql语句如下：
select pro_type,
       sum(decode(bm_tyoe, '房产', jiage1)) 房产场次,
       sum(decode(bm_tyoe, '房产', jiage2)) 房产销售价,
       sum(decode(bm_tyoe, '房产', jiage3)) 房产佣金,
       sum(decode(bm_tyoe, '汽车', jiage1)) 汽车场次,
       sum(decode(bm_tyoe, '汽车', jiage2)) 房产销售价,
       sum(decode(bm_tyoe, '汽车', jiage3)) 汽车佣金,
       sum(decode(bm_tyoe, '奢侈品', jiage1)) 奢侈品场次,
       sum(decode(bm_tyoe, '奢侈品', jiage2)) 奢侈品销售价,
       sum(decode(bm_tyoe, '奢侈品', jiage3)) 奢侈品佣金,
       sum(decode(bm_tyoe, '贵重首饰', jiage1)) 贵重首饰场次,
       sum(decode(bm_tyoe, '贵重首饰', jiage2)) 贵重首饰销售价,
       sum(decode(bm_tyoe, '贵重首饰', jiage3)) 贵重首饰佣金

 group by pro_type
