用database configuration Assistant 引导创建数据库。记得给system,sys 设置自己的口令，便于添加新操作用户。

创建操作用户：

-- 别加双引号，否则，无法用
create user geovindu identified by 888888;
create user geovin identified by 888888;

grant connect,resource,dba to geovindu;

grant connect,resource,dba to geovin;


grant create session,create table,unlimited tablespace to geovindu;
grant create session,create table,unlimited tablespace to geovin;

测试连接：

创建表：

drop table IF EXISTS GEOVINDU.School; 

create table GEOVINDU.School  --創建表
(
    SchoolId char(5) NOT NULL,  --  
    SchoolName varchar(500) NOT NULL,
    SchoolTelNo  varchar(8)  NULL,        
  PRIMARY KEY (SchoolId)   --#主鍵
);

--对表的说明
comment on table GEOVINDU.School is '学校表';
--对表中列的说明
comment on column GEOVINDU.School.SchoolId is 'ID';
comment on column GEOVINDU.School.SchoolName is '名称';
comment on column GEOVINDU.School.SchoolTelNo is '电话号码';

select * from GEOVINDU.School order by SchoolId;
