我有一个名为会计年度的表,其列为start_date,end_date(空表),我希望在每个会计年度之前插入记录直到2060年
FISCAL_YEAR开始dt是7月1日,结束日是明年6月31日
我尝试了什么
irb(main):019:0> date = '2015-04-27T20:00+00:00'
=> "2015-04-27T20:00+00:00"
irb(main):020:0> date = date.sub(/^(\d+)-(\d+)-(\d+)T.*$/,'\3-\2-\1');
irb(main):021:0* date
=> "27-04-2015"
irb(main):022:0>
我如何生成这个序列直到2060年
select add_months(start_date ,-6),add_months(start_date ,6)-1 from (
select to_date('20000101','yyyymmdd') start_date from dual )
basis

你可以这样做:
SELECT
ADD_MONTHS(DATE '1999-07-01', 12*(LEVEL-1)) as fiscal_year_begin,
ADD_MONTHS(DATE '1999-07-01', 12*LEVEL) - INTERVAL '1' DAY AS fiscal_year_end
FROM dual
CONNECT BY LEVEL < 60;
FISCAL_YEAR_BEGIN FISCAL_YEAR_END
1999-07-01 2000-06-30
2000-07-01 2001-06-30
2001-07-01 2002-06-30
2002-07-01 2003-06-30
2003-07-01 2004-06-30
2004-07-01 2005-06-30
2005-07-01 2006-06-30
2006-07-01 2007-06-30
2007-07-01 2008-06-30
2008-07-01 2009-06-30
