Oracle创建表空间、创建用户以及授权、查看权限

--创建临时表空间

create temporary tablespace test_temp

tempfile 'E:\JAVA软件开发安装包\Oracle\=datebase完美安装==win64_11gR2_database_1of2======\oracle_sql_backupoperatar\test_temp.dbf'

size 32M

autoextend on

next 32m maxsize 2048m;

--EXTEND management local SEGMENT SPACE MANAGEMENT AUTO;

--创建用户表空间

create tablespace test_data

logging

datafile 'E:\JAVA软件开发安装包\Oracle\=datebase完美安装==win64_11gR2_database_1of2======\oracle_sql_backupoperatar\test_DATA.dbf'

size 32m

autoextend on

next 32m maxsize 2048m

--extend management local;

--删除表空间  

drop tablespace test_data including contents and datafiles  

---创建用户并制定表空间

create user ricoo identified by ricoo

default tablespace test_data 

temporary tablespace test_temp;

--(临时表空间平时用来放置查询，groupby order by 之内的数据。用完就释放。表空间存的是永久的在oracle数据)

--给用户授权

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 ricoo;

    

--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 ricoo;

---------------------------------------------------------------查看用户权限-----------------------------------

--查看所有用户  dba_开头的是查全库所有的，all_开头的是查当前用户可以看到的，user_开头的是查当前用户的

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;

--3.赋权  

grant connect,resource to demo;  

grant create any sequence to demo;

grant insert any table to demo;  

grant select any table to demo;  

grant unlimited tablespace to demo;  

grant execute any procedure to demo;  

grant update any table to demo;

-------遇到no privileges on tablespace 'tablespace '

alter user userquota 10m[unlimited] on tablespace;

--导入导出命令     

ip导出方式： exp demo/demo@127.0.0.1:1521/orcl file=f:/f.dmp full=y  

exp demo/demo@orcl file=f:/f.dmp full=y  

imp demo/demo@orcl file=f:/f.dmp full=y ignore=y
