connect sys/12345678 as sysdba

create user jsx identified by 123456;

grant create session to jsx;

grant create table to jsx;

connect jsx/123456

create table xs(xh int);

create user jsx2 identified by 123456 password EXPIRE;

grant connect to jsx2;

connect jsx2/123456

alter user jsx3 account lock;  //修改为锁定状态

connect jsx2/123456  // 再次连接会失败

alter user jsx3 account lock;  //修改为解锁状态

创建用户JIA 该用户采用数据库口令认证方式强制要求首次登陆时必须修改口令，将其默认表空间和临时表空间分别设置为USERS和TEMP并在USERS表空间上为其分配10M表空间限额

CREATE USER jia 

IDENTIFIED BY 123456

PASSWORD EXPIRE

DEFAULT TABLESPACE users

QUOTA 10M ON users

TEMPORARY TABLESPACE temp;

练习:

CREATE TABLESPACE ts1

DATAFILE 'D:\ts01.dbf' SIZE 20M REUSE; //创建

表空间

CREATE TEMPORARY TABLESPACE temp1

TEMPFILE 'D:\temp01.dbf' SIZE 20M REUSE; //创建

临时表空间

CREATE USER jiashixin 

IDENTIFIED BY 123456

TEMPORARY TABLESPACE temp1 

DEFAULT TABLESPACE ts1 

QUOTA 10M ON ts1; //创建

用户

CREATE USER user4 

IDENTIFIED BY 123456

TEMPORARY TABLESPACE temp1 

DEFAULT TABLESPACE ts1 

QUOTA 10M ON ts1

QUOTA 10M ON temp1;   //错误创建

用户命令   只能在永久表空空间上分配限额

CREATE USER user6 

IDENTIFIED BY 123456

TEMPORARY TABLESPACE temp1 

DEFAULT TABLESPACE ts1 

QUOTA 10M ON ts1

QUOTA 10M ON users;   //创建

用户命令  可以同时在多个永久表空间分配限额

ALTER USER user6 IDENTIFIED BY 123456789;

ALTER USER user6 QUOTA 5M ON USERS;

 

DROP USER user6;  //CASCADE  可删除与之相关联的对象
