oracle: create new database
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;
