レコードの表示ビューを変更して行に変更する方法

Question

1日に条件（悪い、悪い、悪い）を数え、それを月にグループ化して次のように表示できるSQLがあります。

2009 Apr Bad   5

2009 Apr Worse  2 
2009 Aug Bad   3

私が使用していますSQL：

select years, months, lv, countVal 
from 
(
select years, months, lv, count (lv) OVER (PARTITION BY years,months,lv) countVal from 

(
SELECT x.years, x.months, x.days, x.lv 
FROM airtest, 
XMLTABLE ('$d/cdata/name' passing xmldoc as "d" 
    COLUMNS 
    years integer path 'year', 
    months varchar(3) path 'month', 
    days varchar(2) path 'day', 
    lv varchar(5) path 'value' 
) as X 
    group by x.years, x.months, x.days, x.lv 
    order by x.years, x.months, x.days 
) 
) 
group by years, months, lv, countVal 
order by years,months 

今の問題は、この形式でなるためにそれを変更する方法です??

YEARS MONTHS Bad Poor  Worse 
----- ------ ----- -------- -------- 
2009 Apr  5  3  2 
2009 Aug  3  2  5 
2009 Dec  5  2  3 
......... 
......... 

修正後は、このようになります。

隔離されたデータが毎月の行にグループ化されていることがわかります。

ありがとうございました！

年/月単位で各列とグループへの条件付き合計：

SELECT years, months, 
     SUM(DECODE(lv, 'Bad', countval, 0)) Bad, 
     SUM(DECODE(lv, 'Poor', countval, 0)) Poor, 
     SUM(DECODE(lv, 'Worse', countval, 0)) Worse 
FROM (<your query>) 
GROUP BY years, months

OR

WITH Base_Table AS 
(<your query>) 
SELECT years, months, 
     SUM(DECODE(lv, 'Bad', countval, 0)) Bad, 
     SUM(DECODE(lv, 'Poor', countval, 0)) Poor, 
     SUM(DECODE(lv, 'Worse', countval, 0)) Worse 
FROM base_Table 
GROUP BY years, months
