01-oracle学习环境配置

1.安装oracle与SQL Developer

oracle10g安装教程

2.创建表空间以及用户

表空间是存储数据文件的容器，由数据文件组成，数据库的所有系统数据和用户数据都必须存储在数据文件中。用户数据应该存储在单独的表空间中，必须创建和使用自己的表空间。

--表空间
CREATE TABLESPACE PDSU
  LOGGING
  DATAFILE 'C:\oracletablespace\PDSU.DBF'
  SIZE 100m
  AUTOEXTEND ON
  NEXT 10m;

--创建用户
create user eval--用户
identified by eval--密码
default tablespace PDSU;

--授权
grant dba to eval;

3.创建表

表是数据库中存储数据的数据库对象，每个数据库包含了若干个表，表由行和列组成。

-- student表
CREATE TABLE student
(
    sno char(6) NOT NULL PRIMARY KEY,
    sname char(8) NOT NULL,

comment on column teacher.tname is '姓名';
comment on column teacher.tsex is '性别';
comment on column teacher.tbirthday is '出生日期';
