Oracle创建表空间和用户

/*分为四步 */

---

 

/*第1步：创建临时表空间 */

---

create temporary tablespace emaoyi_temp 
tempfile 'D:\app\Administrator\product\11.2.0\dbhome_1\database\emaoyi_temp.dbf' 
size 10m 
autoextend on 
next 10m maxsize 20480m 
extent management local; 

/*第2步：创建数据表空间 */

---

create tablespace emaoyi 
logging 
datafile 'D:\app\Administrator\product\11.2.0\dbhome_1\database\emaoyi.dbf' 
size 10m 
autoextend on 
next 10m maxsize 20480m 
extent management local; 

/*第3步：创建用户并指定表空间 */

---

create user emaoyi identified by emaoyi 
default tablespace emaoyi
temporary tablespace emaoyi_temp; 

/*第4步：给用户授予权限 */

---

grant connect,resource,dba to emaoyi;

--查询当前表空间

---

select tablespace_name,file_id,file_name,bytes
from dba_data_files
order by file_id

where tablespace_name='emaoyi'

--删除表空间
drop tablespace em;
--删除用户
drop user e [CASCADE];
