一条sql输出本年日历

原创 Linux操作系统 作者:junsansi 时间:2008-03-31 14:55:20 0 删除 编辑

临时想查日历,windows自带的只能按月一月一月翻,一时兴起,通过sql生成了一个全年的日历出来,语句如下:

SQL> select
  2   min(to_char(day, 'yyyy-mm')) month,
  3   min(decode(weekday, 1, day)) "Mon",
  4   min(decode(weekday, 2, day)) "Tue",
  5   min(decode(weekday, 3, day)) "Wed",
  6   min(decode(weekday, 4, day)) "Thu",
  7   min(decode(weekday, 5, day)) "Fri",
  8   min(decode(weekday, 6, day)) "Sat",
  9   min(decode(weekday, 7, day)) "Sun"
 10    from (select day,
 11                 month,
 12                 decode(sign(rn - weekday), 1, week + 1, week) week,
 13                 weekday,
 14                 rn
 15            from (select day,
 16                         to_char(day, 'mm') month,
 17                         to_char(day, 'w') week,
 18                         to_char(day, 'd') weekday,
 19                         row_number() over(partition by to_char(day, 'mm'), to_char(day, 'w') order by day) rn
 20                    from (select trunc(sysdate, 'yyyy') + level - 1 day
 21                            from dual
 22                          connect by rownum <= trunc(sysdate+365,'yyyy')-trunc(sysdate,'yyyy')))) a
 23   group by a.month, a.week
 24   order by a.month, a.week
 25  ;
 
MONTH   Mon         Tue         Wed         Thu         Fri         Sat         Sun
