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=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
   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.
