sql oracle中不带聚合和常量表达式的透视表

我想制作一种透视表，但问题是透视的列必须等于今年和明年。我用一个例子来解释

with
  property(prop_name,  prop_val, planned_year) as (
    select 'BANKING',  'true' , '2018'   from dual union all
    select 'IT'     ,  'false', '2019'  from dual union all
    select 'TELECOM',  'false', '2019'  from dual union all
    select 'MEDIA'  ,  'false', '2020' from dual union all
    select 'APPLE'  ,  'true' , '2018'  from dual union all
    select 'MANGO'  ,  'true' , '2019'   from dual union all
    select 'ORANGE' ,  'false', '2019'   from dual union all
    select 'CARROT' ,  'false', '2019'  from dual union all
    select 'IT' ,  'true' , '2020'   from dual
  )
select *
from   property
pivot  (listagg(prop_val, ',') within group (order by null) 
        for planned_year in ('2019' this_year, '2020' next_year))
;

这就是我想要得到的结果，除了支点必须在今年的计划年（所以不是硬编码的2019年）。我试过这个：

with
  property(prop_name,  prop_val, planned_year) as (
    select 'BANKING',  'true' , '2018'   from dual union all
    select 'IT'     ,  'false', '2019'  from dual union all
    select 'TELECOM',  'false', '2019'  from dual union all
    select 'MEDIA'  ,  'false', '2020' from dual union all
    select 'APPLE'  ,  'true' , '2018'  from dual union all
    select 'MANGO'  ,  'true' , '2019'   from dual union all
    select 'ORANGE' ,  'false', '2019'   from dual union all
    select 'CARROT' ,  'false', '2019'  from dual union all
    select 'IT' ,  'true' , '2020'   from dual
  )
select *
from   property
pivot  (listagg(prop_val, ',') within group (order by null) 
        for planned_year in (EXTRACT(YEAR FROM sysdate) this_year, EXTRACT(YEAR FROM sysdate)+1 next_year))

但是我得到了一个错误：

"non-constant expression is not allowed for pivot|unpivot values"

有人能帮我做这个把戏吗？

我会在这里使用

listag（）

和

case

：

with
  property(prop_name,  prop_val, planned_year) as (
    select 'BANKING',  'true' , '2018' from dual union all
    select 'IT'     ,  'false', '2019' from dual union all
    select 'TELECOM',  'false', '2019' from dual union all
    select 'MEDIA'  ,  'false', '2020' from dual union all
    select 'APPLE'  ,  'true' , '2018' from dual union all
    select 'MANGO'  ,  'true' , '2019' from dual union all
    select 'ORANGE' ,  'false', '2019' from dual union all
    select 'CARROT' ,  'false', '2019' from dual union all
    select 'IT' ,      'true' , '2020' from dual)
select prop_name,
       listagg(case planned_year when to_char(sysdate, 'yyyy') then prop_val end, ',') 
         within group (order by null) this_year,
       listagg(case planned_year when to_char(add_months(sysdate, 12), 'yyyy') then prop_val end, ',') 
         within group (order by null) next_year
  from   property
  group by prop_name
  order by prop_name

请显示您想要的结果。非工作查询不是表达意图的好方法。正如我提到的，我想要的结果是第一个查询的结果。但正如我也提到过的，我不想硬编码“2019”和“2020”，而是想选择今年和明年。
