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.假如缺省的用户具有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=n

查询发现仍然导入了USER表空间
$ sqlplus bjbbs/passwd

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

SQL grant connect,resource to bjbbs;
Grant succeeded.
