能请教一下吗？

查询：

select job_name,to_char(to_date(avg(to_number(to_char(to_date(starttime1,'mm/dd/yyyy hh24:mi:ss'),'SSSSS'))),'SSSSS'),'HH24:MI:SS')AVG_STARTIME
 from TEST2 group by job_name

错误：

ORA-01830: date format picture ends before converting entire input string

它正在处理 table 中的一些记录。这些日期与上面的完全一样。我不明白这种日期格式有什么问题

注意：我使用的是oracle 8i

Answer 1

你之所以这样看你的约会对象，是因为你正在转换它。

实际格式是这样的'yyyy-mm-dd'

所以您的查询应该是：

insert into TEST2 values ('TEST JOB',33,'2015-09-22 19:16:50','2015-09-03 19:17:23',null,null)

Answer 2

我想这就是您要找的

select job_name,to_char(
  to_date(
    TRUNC(avg(
      to_number(
        to_char(
          to_date(starttime1,'mm/dd/yyyy hh24:mi:ss'),
          'SSSSS')
      )
    )),'SSSSS'),'HH24:MI:SS')AVG_STARTIME
 from TEST2 group by job_name

该平均值返回带小数的数字。只需使用 TRUNC 来解决这个问题。

Answer 3

试试这个。你有几个问题。 to_number 的格式掩码应该是 '99999' 而不是 'SSSSS' 并且 avg 函数的结果不是整数，因此 to_date 不起作用。四舍五入的值。

    SELECT job_name,
      TO_CHAR(to_date(ROUND(AVG(to_number(TO_CHAR(to_date(starttime1,'mm/dd/yyyy hh24:mi:ss'),
'SSSSS'),'99999')),0),'SSSSS'),'HH24:MI:SS')AVG_STARTIME
    FROM TEST2
    GROUP BY job_name
