2. 直接导入 数据库测试用户scott/tiger
以管理员身份登录
sql> sqlplus / as sysdba; sql> @utlsampl sql>sqlplus scott/tiger 或者 select username from dba_user where username='scott'
确认执行成功!
3,查看用户表空间
select username,default_tablespace from dba_users where username='scott';
4,查看表空间使用情况
select a.file_id "FileNo", a.tablespace_name "Tablespace_name", a.bytes "Bytes", a.bytes - sum(nvl(b.bytes, 0)) "Used", sum(nvl(b.bytes, 0)) "Free", sum(nvl(b.bytes, 0)) / a.bytes * 100 "%free" from dba_data_files a, dba_free_space b where a.file_id = b.file_id(+) group by a.tablespace_name, a.file_id, a.bytes order by a.tablespace_name;
