1.查看所有用户:select * from dba_users; select * from all_users; select * from user_users;2.查看用户或角色系统权限(直接赋值给用户或角色的系统权限):select * from dba_sys_privs; select * from user_sys_privs; (查看当前用户所拥有的权限)3.查看角色(只能查看登陆用户拥有的角色)所包含的权限sql>select * from role_sys_privs;4.

查看当前用户所在表空间 select username,default_tablespace from user_users; 修改用户默认表空间 alter user 用户名 default tablespace 新表空间; 查看用户所拥有的角色 select * from user_role_privs; 查询数据库中有多少张表 select * from user_tables;

下面两个数据字典视图就知道了.查看有哪些表空间:select * from dba_tablespaces;查看有哪些数据文件在哪个表空间中:select * from dba_data_files; select * from dba_tablespace_groups;

01.查看当前open用户 select username,account_status,expiry_date,profile from dba_users; 02.查看目前的密码过期策略 select * from dba_profiles s where s.profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME'; 03.修改密码过期策略 alter profile default limit password_life_time
