Oracle ORA-06575: 程序包或函数WM_CONCAT处于无效状态
----
--Oracle ORA-06575: 程序包或函数WM_CONCAT处于无效状态
----
失效原因:版本不支持,WM_CONCAT是oracle的非公开函数,并不鼓励使用,新版本oracle并没有带此函数,需要手工加上。
--首先使用dba账号登录oracle数据库
sqlplus sys/sys as sysdba
--解锁wmsys用户 (可以是你自己定义的用户zhangsan、lisi之类的都可以)
alter user wmsys account unlock;
--并为wmsys用户授权,可根据需要授权,不建议授权所有权限
grant all privileges to wmsys;
--如果不知道wmsys用户的密码,可以修改其密码
alter user wmsys identified by 123456;
--使用wmsys用户登录数据库
conn wmsys/123456
--在wmsys下创建可用的wm_concat函数,直接执行以下语句
--定义类型
