查询无效的对象

1、检查无效的数据库对象
select owner,object_name,object_type,status
from dba_objects
where status = 'INVALID';
2、检查不起作用的约束
select owner,constraint_name,table_name,constraint_type,status
from dba_constraints
where status = 'DISABLED';
3、检查无效的触发器
select owner,trigger_name,table_name,status
from dba_triggers
where status = 'DISABLED';
4、检查失效的索引
select index_name,table_name,tablespace_name,status
from dba_indexes
where status <>'VALID';
