resouce是角色，unlimited tablespace是權限。

很多人在進行數據遷移時，希望把數據導入不同于原系統的表空間，在導入之后卻往往發現，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
那么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*Plus:?Release?8.1.7.0.0?-?Production?on?Mon?Sep?22?11:50:03?2003

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??/
SQL>?grant?connect,resource?to?bjbbs;
