Oracle常用命令

查看数据库锁的情况

SELECT object_name, machine, s.sid, s.serial# 

FROM gv$locked_object l, dba_objects o, gv$session s 

WHERE l.object_id　= o.object_id 

AND l.session_id = s.sid; 

 

关闭一个session

ALTER system kill session '305, 48290'; 

 

看一下数据库用的字符集

select * from nls_database_parameters;

获取某个table的列注释

select * from user_col_comments where table_name='ARTI_ARTICLE';

看一下用户用的字符集

select userenv('language') from dual;
