如何把数据导入不同的表空间-

2019-12-02 12:11:20来源:励志吧0次阅读

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.

SQL> exit
