今天在编写存储的时候需要使用到wm_concat这个函数,进行编译的时候提示ORA-30482错误,存储过程大概是如下
create or replace procedure pd_test
(
out_test_query out sys_refcursor
)
is
begin
open out_test_query for
select
wm_concat(distinct(a.name)) name,
wm_concat(distinct(a.age)) age,
wm_concat(distinct(b.school)) school,
wm_concat(distinct(b.score)) score,
wm_concat(distinct(b.course)) course
from
tb_pro_student a,
tb_pro_cource b
where a.name=b.name;
end pd_bill_query_para;
编译的时候提示ORA-30482 :DISTINCT 选项在此函数中禁用的解决方法
解决方法,修改存储过程如下
create or replace procedure pd_test
(
out_test_query out sys_refcursor
)
is
v_sql varchar2(1024);
begin
v_sql:='
open out_test_query for
select
wm_concat(distinct(a.name)) name,
wm_concat(distinct(a.age)) age,
wm_concat(distinct(b.school)) school,
wm_concat(distinct(b.score)) score,
wm_concat(distinct(b.course)) course
from
tb_pro_student a,
tb_pro_cource b
where a.name=b.name';
open out_test_query for v_sql;
end pd_bill_query_para;
该存储过程即将包含vw_concat的语句打包给v_sql,然后直接使用open for即可,测试编译通过,输出结果正确
