系统权限与对象权限
1、系统权限
一、建立用户
SQL> create user dog identified by wangwang;
User created
SQL> create user pig identified by hengheng;
User created
SQL> create user fox identified by youyou;
User created
SQL> create user cat identified by miaomiao;
User created
二、给cat赋权
SQL> grant create session, select any table,create table,create view to cat;
Grant succeeded
三、cat给dog赋权
SQL> conn cat/miaomiao;
Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Connected as cat
SQL> grant create session, select any table,create table,create view to dog;
grant create session, select any table,create table,create view to dog
ORA-01031: 权限不足
给cat赋权时没有再赋权的权力，需加
:WITH ADMIN OPTION
四、收回权限 revoke
SQL> revoke create session, select any table,create table,create view from cat;
Revoke succeeded
五、权限查看
SQL> select * from dba_sys_privs where grantee='CAT';
GRANTEE PRIVILEGE ADMIN_OPTION
------------------------------ -------------------- ------------
2、对象权限8个 execute,alter,select,insert,update,delete,index,references 一、受权emp表给全部用户 SQL> grant select on emp to public; Grant succeeded 查看 SQL> select * from user_tab_privs_made; GRANTEE TABLE_NAME GRANTOR PRIVILEGE GRANTABLE HIERARCHY ------------------------------ ------------------------------ ------------------------------ -------------------- --------- --------- PUBLIC EMP SCOTT SELECT NO NO 二、受权表中某列给用户 SQL> grant update(sal) on emp to cat; Grant succeeded SQL> grant update(job) on emp to cat; Grant succeeded 查看 SQL> select * from user_col_privs_made; GRANTEE TABLE_NAME COLUMN_NAME GRANTOR PRIVILEGE GRANTABLE ------------------------------ ------------------------------ ------------------------------ ------------------------------ -------------------- --------- CAT EMP SAL SCOTT UPDATE NO CAT EMP JOB SCOTT UPDATE NO
