oracle列合并的实现方法

select id,wm_concat(name) from tab_name group by id;

select listagg(id,',') within group (order by id) col_name from tab_name;

create or replace function getRow(table1 varchar2 , ptdb1 varchar2) RETURN VARCHAR2 is
Result VARCHAR2(1000);
begin
FOR cur IN (SELECT audit_code FROM sys_audit_column t2 WHERE table1 =
t2.table_name and ptdb1 = t2.ptdb_name) LOOP
RESULT := RESULT||cur.audit_code||',';
END LOOP;
RESULT:=rtrim(RESULT,',');
return(Result);
end getRow;
