oracle查看用户,用户权限,用户表空间,用户默认表空间命令
查看用户和默认表空间的关系。
select username,default_tablespace from dba_users;
1.查看表结构:desc表名
2.查看当前用户的表:
1.select
table_name
from
user_tables;
3.查看所有用户的表名:
1.select
table_name
from
all_tables;
4.查看所有表名(其中包括系统表)
1.select
table_name
from
all_tables;
5.查看所有的表:
1.select * from tab/dba_tables/dba_objects/cat;
下面介绍Oracle查询用户表空间
◆Oracle查询用户表空间:select * from user_all_tables
◆Oracle查询所有函数和储存过程:select * from user_source
◆Oracle查询所有用户:select * from all_users.select * from dba_users
◆Oracle查看当前用户连接:select * from v$Session
◆Oracle查看当前用户权限:select * from session_privs
◆Oracle查看用户表空间使用情况:
1.select a.file_id "FileNo",a.tablespace_name
2."Tablespace_name",
3.a.bytes "Bytes",a.bytes-sum(nvl(b.bytes,0)) "Used",
4.sum(nvl(b.bytes,0)) "Free",
5.sum(nvl(b.bytes,0))/a.bytes*100 "%free"
6.from dba_data_files a, dba_free_space b
7.where
a.file_id
=
b
.file_id(+)
8.group by a.tablespace_name ,
9.a.file_id,a.bytes order by a.tablespace_name;
1.查看所有用户:
select * from dba_user;
select * from all_users;
select * from user_users;
2.查看用户系统权限:
select * from dba_sys_privs;
select * from all_sys_privs;
select * from user_sys_privs;
3.查看用户对象权限:
select * from dba_tab_privs;
select * from all_tab_privs;
select * from user_tab_privs;
4.查看所有角色:
select * from dba_roles;
5.查看用户所拥有的角色:
select * from dba_role_privs;
select * from user_role_privs;
6.查看角色所拥有的权限:
select * from role_sys_privs;
select * from role_tab_privs;
7.查看所有系统权限
select * from system_privilege_map;
8.查看所有对象权限
select * from table_privilege_map;
以上是在Oracle中查看用户权限 ,
在DB2中为:
select * from syscat.dbauth
或者
get authorizations
查看sid
select * from v$instance
