Question

我正在尝试在（Fusion BI报表）中创建HCM报表，以检索所选年份“所有月份”的员工人数。

在当前情况下，当我们在“ 2017”上运行报表时，它会检索9月，8月，9月的员工总数

需要什么：如果参数=“ 2017”且9月之后的月份为空，则获取“ 9月”中的最后一个现有值

Month Name   Current result    Expected result
July          1                 1
Aug           3                 3 
Sept          4                 4
Oct                             4
Nov                             4
Dec                             4

Answer 1

您必须确保所有月份都以某种方式存在，然后将LAST_VALUE()函数与IGNORE NULLS配合使用，以复制下个月的最后一个非空值。

var yr number;
exec :yr := 2017;
with raw_results(dte, rslt) as (
  select date '2017-07-01', 1 from dual union all
  select date '2017-08-01', 3 from dual union all
  select date '2017-09-01', 4 from dual
)
, min_dte as (
  select min(dte) dte from raw_results
  where dte >= trunc(to_date(:yr,'yyyy'), 'yy')
)
, months as (
  select add_months(dte, level-1) dte
  from min_dte
  connect by extract(year from add_months(dte, level-1)) = :yr
)
select to_char(dte, 'Mon') "Month", 
  last_value(rslt ignore nulls) over(order by dte) "Result"
from months
left join raw_results using(dte);

Month            Result
------------ ----------
Jul                   1
Aug                   3
Sep                   4
Oct                   4
Nov                   4
Dec                   4
