Sql 如何在此查询中使用count语句？

我必须在船上显示起重机每天的工作时间和总箱数。 例如，名为FG1的起重机可能从2019年9月25日晚上8点工作到2019年9月26日凌晨3点。查询需要显示两个信息，即从2019年9月25日晚上8点到晚上11点59分的合计框和从2019年9月26日上午12点到凌晨3点的合计框。问题是，它没有正确计算两个日期之间的合计框

SELECT SUBSTR (b.user_voy, 1, 12) JPVC
  , NVL (SUBSTR (TO_CHAR  (MIN (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-') FIRSTLIFT
  , NVL (SUBSTR (TO_CHAR  (MAX (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-') LASTLIFT
  , (
    select Count(actual_time)
    from tb_gc_odr
    where actual_time IS NOT NULL
      and equ_no = g.equ_no
      and vsl_cd = t.vsl_cd
      AND call_year = t.call_year
      AND call_seq = t.call_seq
    ) as COM_TOTAL
  , SUBSTR((ROUND((((FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24)) * 60) + (MOD(FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24 * 60), 60))) / 60, 2) || ' '), 1, 18) WH
FROM tb_gc_odr g
  , tb_master t
  , tb_berthplan b
WHERE 1 = 1
  AND g.vsl_cd = t.vsl_cd
  AND g.call_year = t.call_year
  AND g.call_seq = t.call_seq
  AND g.cntr_no = t.cntr_no
  AND g.cntr_seq = t.cntr_seq
  AND b.call_year = t.call_year
  AND b.call_seq = t.call_seq
  AND b.vsl_cd = t.vsl_cd
  AND g.cntr_seq = t.cntr_seq
  AND t.cntr_seq = '0'
  AND t.cargo_type <> 'BB'
  AND g.equ_no = 'FG1'
  AND TO_CHAR(g.actual_time, 'MM/DD/YYYY') between '09/23/2019' and '09/26/2019'
GROUP BY t.vsl_cd
  , t.call_year
  , t.call_seq
  , g.equ_no
  , b.user_voy
  , TO_CHAR(g.actual_time, 'MM/DD/YYYY')
order by g.equ_no
  , FIRSTLIFT

期望：

实际结果：

有没有办法在FIRSTLIFT和LASTLIFT之间显示总计框

编辑： 这是我得到的样本数据

没关系。我已经弄明白了。需要添加和到字符时间，'MM/DD/YYYY'=到字符g.actual\u时间，'MM/DD/YYYY'

如果没有样本数据，很难回答这个问题，但您的计算不会将结果限制在指定的时间内

您需要包括以下内容：

(select Count(actual_time) 
from tb_gc_odr 
where actual_time IS NOT NULL 
and equ_no= g.equ_no 
and vsl_cd = t.vsl_cd 
AND call_year = t.call_year 
AND call_seq = t.call_seq 
and actual_time > NVL (SUBSTR (TO_CHAR  (MIN (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-')
and actual_time < NVL (SUBSTR (TO_CHAR  (MAX (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-')
) as COM_TOTAL,

如果您可以显示一些示例数据，以及数据的外观，那么解决问题就容易一点。 但是我想在u使用的子查询中添加，您必须为日期添加更多参数，我认为这些参数包含所有数据

(
  select Count(actual_time) 
  from tb_gc_odr
  where actual_time IS NOT NULL
    and equ_no = g.equ_no 
    and vsl_cd = t.vsl_cd
    AND call_year = t.call_year 
    AND call_seq = t.call_seq
    AND actual_time between '*datefrom*' and '*dateto*'
) as COM_TOTAL

---

你必须过滤数据。我试图解决您的问题

尝试从表tb\u gc\u odr中添加时间分组，如下所示：

select g.*,case 
            when to_char(g.actual_time,'hh24mi') <= 300 or to_char(g.actual_time,'hh24mi')  >= 2000 then 'group 1' 
            when to_char(g.actual_time,'hh24mi') > 300 or to_char(g.actual_time,'hh24mi')  < 2000 then 'group 2'
            end as group_time from tb_gc_odr g

SELECT SUBSTR (b.user_voy, 1, 12) JPVC
  , NVL (SUBSTR (TO_CHAR  (MIN (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-') FIRSTLIFT
  , NVL (SUBSTR (TO_CHAR  (MAX (g.actual_time), 'YYYY-MM-DD HH24:MI:SS'), 1, 20),'-') LASTLIFT
  , (
    select Count(actual_time)
    from tb_gc_odr
    where actual_time IS NOT NULL
      and equ_no = g.equ_no
      and vsl_cd = t.vsl_cd
      AND call_year = t.call_year
      AND call_seq = t.call_seq
    ) as COM_TOTAL
  , SUBSTR((ROUND((((FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24)) * 60) + (MOD(FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24 * 60), 60))) / 60, 2) || ' '), 1, 18) WH
FROM (select g.*,case 
            when to_char(g.actual_time,'hh24mi') <= 300 or to_char(g.actual_time,'hh24mi')  >= 2000 then 'group 1' 
            when to_char(g.actual_time,'hh24mi') > 300 or to_char(g.actual_time,'hh24mi')  < 2000 then 'group 2'
            end as group_time from tb_gc_odr g
            ) g
  , tb_master t
  , tb_berthplan b
WHERE 1 = 1
  AND g.vsl_cd = t.vsl_cd
  AND g.call_year = t.call_year
  AND g.call_seq = t.call_seq
  AND g.cntr_no = t.cntr_no
  AND g.cntr_seq = t.cntr_seq
  AND b.call_year = t.call_year
  AND b.call_seq = t.call_seq
  AND b.vsl_cd = t.vsl_cd
  AND g.cntr_seq = t.cntr_seq
  AND t.cntr_seq = '0'
  AND t.cargo_type <> 'BB'
  AND g.equ_no = 'FG1'
  AND TO_CHAR(g.actual_time, 'MM/DD/YYYY') between '09/23/2019' and '09/26/2019'
GROUP BY t.vsl_cd
  , t.call_year
  , t.call_seq
  , g.equ_no
  , b.user_voy
  , g.group_time
order by g.equ_no
  , FIRSTLIFT

因此，您对完整案例的查询如下：

select g.*,case 
            when to_char(g.actual_time,'hh24mi') <= 300 or to_char(g.actual_time,'hh24mi')  >= 2000 then 'group 1' 
            when to_char(g.actual_time,'hh24mi') > 300 or to_char(g.actual_time,'hh24mi')  < 2000 then 'group 2'
            end as group_time from tb_gc_odr g

      AND call_seq = t.call_seq
    ) as COM_TOTAL
  , SUBSTR((ROUND((((FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24)) * 60) + (MOD(FLOOR(((MAX(g.actual_time)) - (MIN(g.actual_time))) * 24 * 60), 60))) / 60, 2) || ' '), 1, 18) WH

您肯定在查询中缺少联接条件，这就是为什么com_total不正确的原因。我以前尝试过这个方法，但它似乎返回了一个错误。它说这里不允许使用组函数。顺便说一句，我之前已经在post中包含了示例数据，但是结果仍然是一样的。尝试使用>=和
