带分隔符的动态连接忽略空值

问题描述

我有一个包含空值的表：

STREET_NAME	位置	CULVERT_TYPE	CULVERT_WIDTH	CULVERT_MATERIAL
主要街道	从 ST A 到 ST B	下水道风暴\涵洞	1750	波纹钢管
SIDE ST	从 ST C 到 ST D	下水道风暴\涵洞		波纹钢管
	竞技场 1	下水道风暴\涵洞	300
		下水道风暴\涵洞	500
.

with cte as (
select 'MAIN ST' as STREET_NAME,'FROM ST A TO ST B' as LOCATION,'SEWER STORM \ CULVERT' as CULVERT_TYPE,1750 as CULVERT_WIDTH,'CORRUGATED STEEL PIPE' as CULVERT_MATERIAL
from dual
union all
select 'SIDE ST' as STREET_NAME,'FROM ST C TO ST D' as LOCATION,null as CULVERT_WIDTH,'CORRUGATED STEEL PIPE' as CULVERT_MATERIAL
from dual
union all
select null as STREET_NAME,'ARENA 1' as LOCATION,300 as CULVERT_WIDTH,null as CULVERT_MATERIAL
from dual
union all
select null as STREET_NAME,null as LOCATION,500 as CULVERT_WIDTH,'' as CULVERT_MATERIAL
from dual
union all
select null as STREET_NAME,null as CULVERT_TYPE,null as CULVERT_MATERIAL
from dual
)
select * from cte

我想将这些值连接到以竖线分隔的 | 列中（并忽略空值）。

CULVERT DESCRIPTION
----------------------
MAIN ST | FROM ST A TO ST B | SEWER STORM \ CULVERT | 1750 | CORRUGATED STEEL PIPE
SIDE ST | FROM ST C TO ST D | SEWER STORM \ CULVERT | CORRUGATED STEEL PIPE
ARENA 1 | SEWER STORM \ CULVERT | 300
SEWER STORM \ CULVERT | 500
<null>

问题：

有没有办法像在 Oracle 18c 中那样进行动态连接，同时忽略空值？

如果解决方案是一个易于阅读的简单函数，那将是理想的，例如：

dyamic_concat( delimiter,parameters [ column1,column2,column3 ]... )
