Oracle中使用decode進行數(shù)據(jù)的列轉(zhuǎn)換為行的試驗

如何將以下數(shù)據(jù)格式的數(shù)據(jù)轉(zhuǎn)換為
初始化格式如下：
1    市政府    房產(chǎn)    1    2    3
2    省政府    房產(chǎn)    4    3    4-

處理sql語句如下：
select pro_type,
       sum(decode(bm_tyoe, '房產(chǎn)', jiage1)) 房產(chǎn)場次,
       sum(decode(bm_tyoe, '房產(chǎn)', jiage2)) 房產(chǎn)銷售價,
       sum(decode(bm_tyoe, '房產(chǎn)', jiage3)) 房產(chǎn)傭金,
       sum(decode(bm_tyoe, '汽車', jiage1)) 汽車場次,
       sum(decode(bm_tyoe, '汽車', jiage2)) 房產(chǎn)銷售價,
       sum(decode(bm_tyoe, '汽車', jiage3)) 汽車傭金,
       sum(decode(bm_tyoe, '奢侈品', jiage1)) 奢侈品場次,
       sum(decode(bm_tyoe, '奢侈品', jiage2)) 奢侈品銷售價,
       sum(decode(bm_tyoe, '奢侈品', jiage3)) 奢侈品傭金,
       sum(decode(bm_tyoe, '貴重首飾', jiage1)) 貴重首飾場次,
       sum(decode(bm_tyoe, '貴重首飾', jiage2)) 貴重首飾銷售價,
       sum(decode(bm_tyoe, '貴重首飾', jiage3)) 貴重首飾傭金
