/*分为四步 */
/*第1步：创建临时表空间  */
create temporary tablespace user_temp  
tempfile 'D:\oracle\oradata\Oracle9i\user_temp.dbf'
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

/*第2步：创建数据表空间  */
create tablespace IDSS_DEV_USER
logging  
datafile 'F:\oracle\product\10.2.0\oradata\orcl\IDSS_DEV_USER.dbf'
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

/*第3步：创建用户并指定表空间  */
create user username identified by password  
default tablespace user_data  
temporary tablespace user_temp;  

/*第4步：给用户授予权限  */
grant connect,resource,dba to username;

删除表空间

drop tablespace tablespace_name including contents and datafiles;

修改表空间
alter user test1 default tablespace user_tbs
查看用户权限
select * from user_role_privs;
select * from session_privs

oracle 导入命令
imp IDSS_DEV_USER/IDSS_DEV_USER file=F:\sogo/IDSS_ALL.dmp log=f:\sogo/dblog  full=y ignore=y

idss_dev_user

IDSS_ALL.dmp 表空间文件
IAS_TBS
OMCW_TBS

alter user kcgl default tablespace kcgl temporary tablespace temp;

针对某个用户的:
alter user user_name default tablespace tbs_name;

设置数据库的默认临时表空间:
Alter database default temporary tablespace temp_tbs_name;

select username from dba_users

导出
exp username/passwd@dbname tables= tablename file=filename.dmp rows=n compress=n

exp IDSS_DEV_USER/IDSS_DEV_USER@dbname tables= tablename file=filename.dmp rows=n compress=n
Oracle中如何查询所有表及其所使用的表空间
select owner,table_name,tablespace_name from dba_tables;
