具体操作如下:
1)、运行->sqlplus /nolog
2)、输入conn / as sysdba 管理员账户登录
3)、如果用户被锁定先解锁:alter user system account unlock;
4)、修改密码:alter user system identified by qiushun;
确保路径存在,比如【D:\oracle\oradata\Oracle9i\】也就是你要保存文件的路径存在
/*第1步:创建临时表空间 */
create temporary tablespace user_temp
tempfile 'D:\oracle\oradata\Oracle9i\user_temp.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;
/*第2步:创建数据表空间 */
create tablespace user_data
logging
datafile 'D:\oracle\oradata\Oracle9i\user_data.dbf'
size 50m
autoextend on
next 50m maxsize 20480m

/*第3步:创建用户并指定表空间 */
create user username identified by password
default tablespace user_data
temporary tablespace user_temp;
/*第4步:给用户授予权限 */
grant connect,resource,dba to username;
/*第5步:删除用户 */
drop user username cascade;
/*第6步:删除表空间 */
drop tablespace user_data(or user_temp)
including contents and datafiles cascade constraints;
// including contents 删除表空间内容,否则非空表空间删不掉
// cascade constraints 删除表空间的外键参照
