使用SQL查询出今年及上一年的每个月份

[Gabe_Newell]

如：今年是2016年，则结果为
2015-01
2015-02
2015-03
.
.

2016-11
2016-12

时间 between to_date(to_char(sysdate,'yyyy')-1||'-1-1 0:0:0','yyyy-mm-dd hh24:mi:ss') and sysdate，后面按年月group by一下

[蓝色蛋饼]

select to_char(add_months(to_date('2016' || '1231', 'yyyy-mm-dd'),
                          -level + 1), --从2016年年底往上计算24个月
               'YYYY-MM') mon
  from dual
connect by level <= 24 --2年24个月
 order by mon;

单纯的查出两年的所有月份容易实现，看你具体需求吧~
