1、创建directory
JZH@test>create directory test_dir as '/home/oracle/';
Directory created.
2、创建测试表
JZH@test>create table emp1 as select * from scott.emp;
Table created.
3、查看表所在表空间
JZH@test>select owner,table_name,tablespace_name from dba_tables where table_name='EMP1';
OWNER TABLE_NAME TABLESPACE_NAME

4、查询emp1表
select empno,ename,sal,comm from emp1;
EMPNO ENAME SAL COMM
---------- ---------- ---------- ----------
7369 SMITH 1900
7499 ALLEN 1600 300
7521 WARD 1250 500

14 rows selected.
Package body created.
5、更改表名，更改表空间，更改用户
impdp park/park dumpfile=emp1.dmp directory=test_dir logfile=emp1.log remap_schema=jzh:park remap_tablespace=users:example remap_table=emp1:emp2
6、检查结果
PARK@test>select owner,tablespace_name from dba_tables where table_name='EMP2';
OWNER TABLE_NAME TABLESPACE_NAME
------------------------------ ------------------------------ ------------------------------
PARK EMP2 EXAMPLE
用户已由jzh更改为park,表名由EMP1更改为EMP2，表空间由USERS更改为EXAMPLE
6、查询数据
PARK@test>select empno,comm from emp2;
EMPNO ENAME SAL COMM
---------- ---------- ---------- ----------
7369 SMITH 1900
7499 ALLEN 1600 300

OK，完成！

补充：

/*第1步：创建临时表空间 */
create temporary tablespace AZTJ_temp
tempfile 'D:\data\AZTJ_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 TPAZTJ
logging
datafile 'D:\data\TPAZTJ.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 用户名 identified by 密码
default tablespace TPAZTJ
temporary tablespace AZTJ_temp ;

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

/* 导出 */
