Oracle 常用系统表

1、查询一直列明在哪些表中出现

SELECT t.owner,t.table_name FROM all_tab_columns t WHERE t.COLUMN_NAME ='XXXXX' AND .....

2、表被锁以及解锁

--查询锁表对象
select object_name,machine,s.sid,s.serial#
from v$locked_object l,dba_objects o ,v$session s
where l.object_id　=　o.object_id and l.session_id=s.sid;
--关闭锁表的会话
alter system kill session 'sid,seial#';

3、存储过程被锁

--查找sid
select sid,object from v$access where  object like '%XXXXX%'
--查询sid,serial#
select sid,serial# ,paddr from v$session where sid = '';
--kill session
alter system kill session 'sid,serial#';
