文档解释
ORA-12025: materialized view log on “string”.”string” already has primary keys
Cause: Materialized view log on the indicated table already has primary key columns.
Action: No action required.
ORA-12025错误是指当创建Materialized View log时,系统发现表上已存在主键时,抛出的错误。
官方解释
这是一个警告性错误,表明Materialized View日志会忽略上存在的主键。由于Materialized View日志会根据其表创建自己的主键,因此如果主键存在,则请尝试先删除上存在的主键。
正常处理方法及步骤
1、使用以下SQL语句检查哪些表存在主键:
SELECT table_name FROM user_constraints WHERE CONSTRAINT_TYPE = ‘P’;
2、删除上述表上存在的主键:
ALTER TABLE
