Oracle数据库中如何将一个备份库中的一个表导入到现有的库中？

create / public / database link dblinkname
　　connect to dbusername identified by dbpassword
　　using '(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = 备份库IP)(PORT = 备份库port)))(CONNECT_DATA =(SERVICE_NAME = 备份库name)))';

do something from 表@dblinkname

//create table xxx as select * from 表@dblinkname
