oracle如何把数据导入不同的表空间

很多人在进行数据迁移时，希望把数据导入不同于原系统的表空间，在导入之后却往往发现，数据被导入了原表空间。
本例举例说明解决这个问题:
1.如果缺省的用户具有DBA权限
那么导入时会按照原来的位置导入数据，即导入到原表空间

$ imp bjbbs/passwd file=bj_bbs.dmp fromuser=jive touser=bjbbs grants=nImport: Release 8.1.7.4.0 - Production on Mon Sep 22 11:49:41 2003(c) Copyright 2000 Oracle Corporation.

查询发现仍然导入了USER表空间

2.回收用户unlimited tablespace权限
这样就可以导入到用户缺省表空间

SQL> create user bjbbs identified by passwd  2  default tablespace bjbbs  3  temporary tablespace temp  4  /User created.SQL> grant connect,resource to bjbbs;Grant succeeded.SQL> grant dba to bjbbs;Grant succeeded.SQL> revoke unlimited tablespace from bjbbs;Revoke succeeded.SQL> alter user bjbbs quota 0 on users;User altered.SQL> alter user bjbbs quota unlimited on bjbbs;User altered.SQL> exitDisconnected from Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit ProductionWith the Partitioning optionJServer Release 8.1.7.4.0 - 64bit Production

重新导入数据
