imp导入表时，提示：对表空间‘ICITY’无权限。
经过百度，查看到用DBA的用户登陆，写SQL语句执行即可授权。
alert user dg_bagsh quota unlimited on icity;
alert user dg_bagsh quota unlimited on icity;
alert user dg_bagsh quota unlimited on icity;
alert user dg_bagsh quota unlimited on icity;
alert user dg_bagsh quota unlimited on icity;
alter user dg_bagsh quota unlimited on icity;
一句即可，我是为了巩固自己的记忆，顺便就多写了几遍。
