oracle12c如何创建练习用户scott

1.进入cmd命令窗口，连接oracle数据库

sqlplus / as sysdba

2.创建c##scott用户(这里创建的用户为:c##scott，密码为:tiger)

create user c##scott identified by tiger

3.为用户授权

grant connect,resource,unlimited tablespace to c##scott container=all;





[sql] view plain copy




4.设置用户使用的表空间

alter user c##scott default tablespace users;

alter user c##scott temporary tablespace temp;

5.使用c##scott用户登录

connect c##scott/tiger

6.显示当前登录的用户

show user



使用SQL Developer创建连接，并使用c##scott用户登录


将以下创建表及其插入表中数据的sql语句执行。记得最后 commit;语句[sql] view plain copy
