如何把數據導入不同的表空間?

很多人在進行數據遷移時，希望把數據導入不同於原系統的表空間，在導入之後卻往往發現，數據被導入了原表空間。
本例舉例說明解決這個問題:
1.如果缺省的用戶具有DBA權限
那麼導入時會按照原來的位置導入數據，即導入到原表空間

$ imp bjbbs/passwd file=bj_bbs.dmp fromuser=jive touser=bjbbs grants=n

查詢發現仍然導入了USER表空間

$ sqlplus bjbbs/passwd

SQL> select table_name,tablespace_name from user_tables;

2.回收用戶unlimited tablespace權限
這樣就可以導入到用戶缺省表空間

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> exit

現在數據被導入到正確的用戶表空間中.
