Oracle创建表空间、创建用户以及授权、查看权限常用sql语句

查看所有用户

SELECT * FROM DBA_USERS;
SELECT * FROM ALL_USERS;
SELECT * FROM USER_USERS;

查看用户系统权限

SELECT * FROM DBA_SYS_PRIVS;
SELECT * FROM USER_SYS_PRIVS;

查看用户对象或角色权限

SELECT * FROM DBA_TAB_PRIVS;
SELECT * FROM ALL_TAB_PRIVS;
SELECT * FROM USER_TAB_PRIVS;

查看所有角色

SELECT * FROM DBA_ROLES;

查看用户或角色所拥有的角色

SELECT * FROM DBA_ROLE_PRIVS;

SELECT * FROM USER_ROLE_PRIVS;

 创建临时表空间

CREATE TEMPORARY TABLESPACE myf_temp
TEMPFILE '/u01/app/oracle/oradata/db/myf_temp01.dbf'
SIZE 32M
AUTOEXTEND ON
NEXT 32M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL;

创建用户表空间

CREATE TABLESPACE myf_data
LOGGING
DATAFILE '/u01/app/oracle/oradata/db/MYF_DATA01.DBF'
SIZE 32M
AUTOEXTEND ON
NEXT 32M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL;

创建用户并制定表空间

CREATE USER username IDENTIFIED BY password
DEFAULT TABLESPACE TEST_DATA
TEMPORARY TABLESPACE TEST_TEMP;

给用户授予权限

GRANT
　　CREATE SESSION, CREATE ANY TABLE, CREATE ANY VIEW ,CREATE ANY INDEX, CREATE ANY PROCEDURE,
　　ALTER ANY TABLE, ALTER ANY PROCEDURE,
　　DROP ANY TABLE, DROP ANY VIEW, DROP ANY INDEX, DROP ANY PROCEDURE,
　　SELECT ANY TABLE, INSERT ANY TABLE, UPDATE ANY TABLE, DELETE ANY TABLE
　　TO username;

将role这个角色授与username,也就是说，使username这个用户可以管理和使用role所拥有的资源
GRANT role TO username;
