如果是，那么你的c##scott用户，有没有select 这张表scott.emp的权限，如果没有，那么相反scott用户有没有在c##scott用户下create表的权限？如果二者都没有，那么你只能用dba用户授权，或者用dba用户授权，或者就用dba用户做。
主要语句就是create table as select * from scott.emp。根据使用用户的不同而有所不同。
如果scott.emp中的数据非常多，那么如果你的服务器比较好，那么可以直接这么做，稍等会就好了。
如果你的服务器比较烂，那么可能你需要先 create table as select * from scott.emp WHere 1=2;
先导过去一张空表，然后再分批insert数据。
数据完成后，建立相应的索引等等。
至于倒完后，个人建议原表不要删除，因为没准什么时候客户心血来潮还会用到的。
如果不是内部表而是emp命令倒出来的表，要用imp导入，那么要用到fromuser，touser，写法有点点忘了，网上很多，好长时间不用emp导不同用户，记不住了。
