Question

我有一个SQL可以计算一天中的条件（差，差，更差）并将其分组为一个月并显示如下：

 2009 Apr    Poor         3

 2009 Aug    Bad          3

我正在使用的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

现在的问题是如何将其修改成这种格式？

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

修改后，它会变成这样的东西。

您可以看到每个月将分开的数据分组成一行。

感谢您的帮助!!

有条件地按年/月汇总到每个列和组：

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

[Gaurav Soni补充以下内容]

或

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
