create user 用户名 identified by 密码 default tablespace 缺省表空间 Temporary tablespace 临时表空间;
grant connect,resource,dba to 用户名;
revoke unlimited tablespace from 用户名;
alter user 用户名 quota 0 on Users;
alter user 用户名 quota unlimited on 用户缺省表空间;
--关键是后面3行命令，必须执行。
--接着使用IMP工具导入数据即可导入到用户缺省表空间.

--DROP USER GROUPCMS CASCADE;
create user GROUPCMS identified by ABC123 default tablespace GROUPCMS ;
