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,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.
添加83天到您的日期并将其截断为全年：
