创建视图，及在视图里查询没问题，但是在C#一调用，就报ORA-22922 ，找了一些方法，包括用：
listagg(city,',') within GROUP (order by city) ，感觉多少有点问题，listagg列传行无分隔，也许我没理解透，项目着急先上能用的。
后来找到高手的代码参考复制，居然还能用，zh_concat列传行用：分隔，还凑合。
使用时，就把wm_concat用zh_concat替换了一下，就Ok了。
create or replace TYPE zh_concat_im
AUTHID CURRENT_USER AS OBJECT

MEMBER FUNCTION ODCIAGGREGATEMERGE(SELF IN OUT zh_concat_im,

create or replace TYPE BODY zh_concat_im

函数：
create or replace FUNCTION zh_concat(P1 VARCHAR2)
RETURN VARCHAR2 AGGREGATE USING zh_concat_im ;
