Oracle中查看無效的對象、約束、觸發器和索引

轉自：http://blog.itpub.net/28408358/viewspace-764437/

1、檢查無效的數據庫對象：

SELECT owner, object_name, object_type,status 

FROM dba_objects 

WHERE status = 'INVALID'; 

2、檢查不起作用的約束：

SELECT owner, constraint_name, table_name, constraint_type, status

FROM dba_constraints

WHERE status = 'DISABLED';

3、檢查無效的觸發器：

SELECT owner, trigger_name, table_name, status

FROM dba_triggers

WHERE status = 'DISABLED'; 

4、檢查失效的索引：

select index_name,table_name,tablespace_name,status

 From dba_indexes 

Where status<>'VALID';
