Oracle SQL多列对齐到单个范围/传奇

斯汀普森

我的应用程序中有一个活动表。它具有项目ID，活动ID，基准完成日期，实际完成日期，计划完成日期和延迟完成日期。

我想在每个日期列中获取项目每个星期的活动ID计数。然后，我想获取这些日期列中的每一个，并将它们相对绘制。

最终结果将是一条曲线，显示第二周的活动数量与第二周的实际活动数量，第二周的计划活动数量以及第二周的后期活动数量。

我可以这样做来显示数据...

SELECT ACTIVITY.PROJECTOBJECTID,
       ACTIVITY.OBJECTID,
       TRUNC(ACTIVITY.BASELINEFINISHDATE,'W')+7 AS BLFIN,
       TRUNC(ACTIVITY.ACTUALFINISHDATE,'W')+7 AS AFIN,
       TRUNC(ACTIVITY.FINISHDATE,'W')+7 AS FIN,
       TRUNC(ACTIVITY.REMAININGLATEFINISHDATE,'W')+7 AS LFIN
  FROM PXRPTUSER.ACTIVITY ACTIVITY
 WHERE (ACTIVITY.PROJECTOBJECTID = :POID)

但是，现在我有四个日期列。理想情况下，我想要四个计数列和一个日期列。这是我必须使用的数据示例。

PID     AID     BLFIN     AFIN  FIN         LFIN

下面的查询给出了描述的结果。WKN列是ISO标准中的星期数，您可能需要将其更改为其他名称。“ WW”。另外，如果您有不同年份的日期，则必须在查询中连接年份（在bf，af，pf和lf子查询中将year附加到wkn）。

with 
bf as (select to_char(blfin, 'iw') wkn, count(aid) cnt 
  from activity group by to_char(blfin, 'iw')),
af as (select to_char(afin, 'iw') wkn, count(aid) cnt 
  from activity group by to_char(afin, 'iw')),
pf as (select to_char(fin, 'iw') wkn, count(aid) cnt 
  from activity group by to_char(fin, 'iw')),
lf as (select to_char(lfin, 'iw') wkn, count(aid) cnt 
  from activity group by to_char(lfin, 'iw'))
select wkn, nvl(bf.cnt, 0) as baseline, nvl(af.cnt, 0) as actual, 
    nvl(pf.cnt, 0) as planned, nvl(lf.cnt, 0) as late
  from bf
    full join af using (wkn)
    full join pf using (wkn)
    full join lf using (wkn)
  where wkn is not null
  order by wkn

结果：

  WKN BASELINE ACTUAL   PLANNED  LATE
  --- -------- -------- -------- --------
  08        24        0       24        1
  15        14        0       14        0
  17         1        0        1        0
  20         2        0        2        0
  25         0        0        0       40
