1、权限（privilege）： 【system privilege（系统权限）：针对于database 的相关权限 object privilege （对象权限）：针对于schema 的object】 |

2、查看系统权限 |

3、分配、回收系统权限 |
||||
|
grant——with admin option 【如果用户获得权限时，设置此参数，用户可以将权限再授予别的用户】 SYS @ prod > grant select any table to scott with admin option; Grant succeeded. SYS @ prod > conn scott/tiger Connected. SCOTT @ prod > col usrname for a10 SCOTT @ prod > col privilege for a30 SCOTT @ prod > select * from user_sys_privs; USERNAME PRIVILEGE ADMIN_OPT --------------- ------------------------------ --------- SCOTT UNLIMITED TABLESPACE NO SCOTT SELECT ANY TABLE YES SCOTT @ prod > grant select any table to tom; Grant succeeded. SCOTT @ prod > conn tom/tom Connected. TOM @ prod > select * from user_sys_privs; USERNAME PRIVILEGE ADMIN_OPT --------------- ------------------------------ --------- TOM SELECT ANY TABLE NO TOM CREATE SESSION NO TOM UNLIMITED TABLESPACE NO TOM @ prod > select * from scott.emp where rownum <3; EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ---------- --------- ---------- --------- ---------- ---------- ---------- 7369 SMITH CLERK 7902 17-DEC-80 800 20 7499 ALLEN SALESMAN 7698 20-FEB-81 1600 300 30 ——【revoke with admin option ，在回收权限时，不能级联】。 TOM @ prod > conn /as sysdba Connected. SYS @ prod > revoke select any table from scott; Revoke succeeded. SCOTT @ prod > conn scott/tiger Connected. SCOTT @ prod > select * from user_sys_privs; USERNAME PRIVILEGE ADMIN_OPT --------------- ------------------------------ --------- SCOTT UNLIMITED TABLESPACE NO SCOTT @ prod > conn tom/tom Connected. TOM @ prod > select * from user_sys_privs; USERNAME PRIVILEGE ADMIN_OPT --------------- ------------------------------ --------- TOM SELECT ANY TABLE NO TOM CREATE SESSION NO TOM UNLIMITED TABLESPACE NO ——【必须一一收回】 TOM @ prod > conn /as sysdba Connected. SYS @ prod > revoke select any table from tom; Revoke succeeded. SYS @ prod > conn tom/tom Connected. TOM @ prod > select * from user_sys_privs; USERNAME PRIVILEGE ADMIN_OPT --------------- ------------------------------ --------- TOM CREATE SESSION NO TOM UNLIMITED TABLESPACE NO |

4、对象权限 |
||||
|
grant ---------with grant option ——【如果用户获得权限时，设置此参数，用户可以将权限再授予别的用户】 SYS @ prod > grant all on scott.emp to public; ——【all 代表所有的对象权限，public 代表所有的用户 】 SYS @ prod > conn tom/tom Connected. TOM @ prod > select * from user_tab_privs; no rows selected 【在视图user_tab_privs没有记载，但是权限是授予的了，一样可以执行权限【如果是系统权限就会在user_sys_privs上显示信息】】 TOM @ prod > select ename from scott.emp; ENAME ------------------------------ SMITH ALLEN WARD JONES MARTIN BLAKE CLARK SCOTT KING TURNER ADAMS JAMES FORD MILLER 14 rows selected. TOM @ prod > delete from scott.emp; 14 rows deleted. TOM @ prod > rollback; Rollback complete. TOM @ prod > conn /as sysdba Connected. SYS @ prod > revoke all on scott.emp from public; ——【回收权限】 Revoke succeeded. SYS @ prod > grant update on scott.emp to tom with grant option; Grant succeeded. SYS @ prod > create user rose identified by rose ; User created. SYS @ prod > grant create session to rose; Grant succeeded. SYS @ prod > conn tom/tom Connected. GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE GRANTABLE HIERARCHY ---------- --------------- --------------- --------------- --------------- --------------- --------------- TOM SCOTT EMP1 SCOTT UPDATE YES NO TOM @ prod > grant update on scott.emp to rose; Grant succeeded. TOM @ prod > conn rose/rose Connected. ROSE @ prod > select * from user_tab_privs; GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE GRANTABLE HIERARCHY ---------- --------------- --------------- --------------- --------------- --------------- --------------- ROSE SCOTT EMP1 TOM UPDATE NO NO ——【revoke with grant option ，在回收权限时，级联。】 ROSE @ prod > conn /as sysdba Connected. SYS @ prod > revoke update on scott.emp from rose; revoke update on scott.emp from rose * ERROR at line 1: ORA-01927: cannot REVOKE privileges you did not grant ----只能从直接授予者回收权限 SYS @ prod > revoke update on scott.emp from tom; Revoke succeeded. SYS @ prod > conn tom/tom Connected. TOM @ prod > select * from user_tab_privs; GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE GRA HIE -------------------- ---------- ---------- ---------- ---------------------------------------- --- --- TOM SCOTT EMP SCOTT SELECT NO NO ——针对列授予对象权限 SYS @ prod >grant update(sal) on scott.emp to tom; Grant succeeded. SYS @ prod > conn tom/tom Connected. TOM @ prod > update scott.emp set comm=100 where empno=7788; ——对该列无权限修改 update scott.emp set comm=100 where empno=7788 * ERROR at line 1: ORA-01031: insufficient privileges TOM @ prod > update scott.emp set sal=10000 where empno=7788; 1 row updated. TOM @ prod > rollback; Rollback complete. TOM @ prod > select GRANTEE,OWNER,TABLE_NAME,COLUMN_NAME,PRIVILEGE from user_col_privs; GRANTEE OWNER TABLE_NAME COLUMN_NAME PRIVILEGE ---------- --------------- --------------- --------------- --------------- TOM SCOTT EMP SAL UPDATE |

与权限相关的视图 |

SESSION_PRIVS 【用户当前会话拥有的系统权限】 USER_ROLE_PRIVS 【用户被授予的角色】 ROLE_SYS_PRIVS 【用户当前拥有的角色的系统权限】 USER_SYS_PRIVS 【直接授予用户的系统权限】 USER_TAB_PRIVS 【授予用户的对象权限 包含了当前用户给其他用户的对象权限和其他用户给当前用户的对象权限】 ROLE_TAB_PRIVS 【授予角色的表的权限】 USER_TAB_PRIVS_RECD 【其他用户给当前用户的对象权限】 USER_TAB_PRIVS_MADE 【当前用户给其他用户的对象权限】 USER_COL_PRIVS_MADE 【在用户对象列一级上被分配的对象权限】 USER_COL_PRIVS_RECD 【在指定列上分配给用户的对象权限】 【显示用户授出的列权限【user_col_privs_made】
【显示用户所具有的列权限】
【显示用户所授出的对象权限】
【显示用户所具有的对象权限（收到）】
