Oracle 查询两个时间段内的所有日期列表

1、查询某时间段内日期列表 

select level,to_char(to_date(\'2013-12-31\',\'yyyy-mm-dd\')+level-1,\'yyyy-mm-dd\') as date_time  
from dual 
connect by level <=to_date(\'2014-01-03\',\'yyyy-mm-dd\')-to_date(\'2013-12-31\',\'yyyy-mm-dd\')+1 

2、查询前两个月日期列表 

1 SELECT T.DATE_ID FROM ( 
2 select to_char(ADD_MONTHS( TO_DATE(to_char(sysdate-1,\'yyyyMMdd\'),\'yyyyMMdd\' ) ,- 2)+ rownum,\'yyyyMMdd\' ) DATE_ID 
3 from dual 
4 connect by rownum <=to_date(to_char(sysdate-1,\'yyyyMMdd\'),\'yyyyMMdd\')-ADD_MONTHS( TO_DATE(to_char(sysdate-1,\'yyyyMMdd\'),\'YYYYMMDD\' ) ,- 2 ) 
5 ) t order by DATE_ID desc 

 

3.查询月份列表 

1 SELECT TO_CHAR(ADD_MONTHS(TO_DATE(\'2014-10\', \'yyyy-MM\'), ROWNUM - 1), 
2                \'yyyyMM\') as monthlist 
3   FROM DUAL 
4 CONNECT BY ROWNUM <= 
5            months_between(to_date(\'2015-06\', \'yyyy-MM\'), 
6                           to_date(\'2014-10\', \'yyyy-MM\')) + 1 

4.年份列表 

 1 SELECT 
 2     TO_CHAR( ADD_MONTHS( TO_DATE( \'2014-10\' ,\'yyyy-MM\' ) ,( ROWNUM - 1 ) * 12 ) ,\'yyyy\' ) AS yearlist 
 3 FROM 
 4     DUAL CONNECT BY ROWNUM <= months_between( 
 5         to_date( 
 6             \'2015-06\' , 
 7             \'yyyy-MM\' 
 8         ) , 
 9         to_date( 
10             \'2014-10\' , 
11             \'yyyy-MM\' 
12         ) 
13     ) / 12 + 1
