按财政年度分组(Oracle)

Question

在Oracle中有没有办法可以拉动风云？我用下面的脚本只拉了两个风云.Mytable日期范围从1998财年到2009财年.

 SELECT 'FY2008' as FY, 
         Site, 
         COUNT(*) 
    FROM mytable 
   WHERE date >='10-OCT-2007' 
     AND date <'10-OCT-2008' 
GROUP BY site

 SELECT 'FY2008' as FY, 
         Site, 
         COUNT(*) 
    FROM mytable 
   WHERE date >='10-OCT-2008' 
     AND date <'10-OCT-2009' 
GROUP BY site

拉动两个FY是可以的,但是当拉动超过10 FY时它太重复了.

Answer 1

添加83天到您的日期并将其截断为全年:

select 'FY'||TRUNC(date + 83, 'YYYY') as FY, Site, count(*)
from mytable
group by 'FY'||TRUNC(date + 83, 'YYYY'), site
