本文旨在简单的入门……

首先呢，安装好PostgreSQL，最基本的要求。

其中，pgAdmin是图形界面，为了方便尽量安装上吧。

许多同学第一次使用的时候会遇到新建服务器登记的问题，我查了一下，鉴于我们只是作为练习使用，可以很简单方便的用本机作为服务器，本机服务器参数如下：

mac postgresql创建数据库 pg数据库怎么建表_mac postgresql创建数据库

点击确定就好了。

接下来建立数据库：

mac postgresql创建数据库 pg数据库怎么建表_数字电路_02

右键单击新建

mac postgresql创建数据库 pg数据库怎么建表_mac postgresql创建数据库_03

名称随意。

接下来建立数据表：

mac postgresql创建数据库 pg数据库怎么建表_右键_04

同样右键单击

mac postgresql创建数据库 pg数据库怎么建表_右键_05

这里可以复制代码：

--DROP TABLE department CASCADE;
--DROP TABLE student CASCADE;
--DROP TABLE course CASCADE;
--DROP TABLE sc CASCADE;

--department(dNo,dName,officeRoom,homepage)
--student(sNo,sName,sex,age,dNo)
--course(cNo,cName,cPNo,credit,dNo)
--sc(sNo,cNo,score,recordDate)

CREATE TABLE department(
  dNo           CHAR(2)        NOT NULL UNIQUE,
  dName         VARCHAR(20),
  officeRoom    VARCHAR(40),
  homePage      VARCHAR(80),
  PRIMARY KEY(dNo)
);

CREATE TABLE student(
  sNo       CHAR(6)        NOT NULL UNIQUE,
  sName     VARCHAR(20)    NOT NULL,
  sex       CHAR(2)        CHECK (sex IN('男','女')),      
  age       INT,
  dNo       CHAR(2),
  PRIMARY KEY(sNo),
  FOREIGN KEY (dNo) REFERENCES  department(dNo)
);

CREATE TABLE course(
  cNo       CHAR(6)        NOT NULL UNIQUE,
  cName     VARCHAR(20)    NOT NULL,
  cPNo      CHAR(6),
  credit    INT,
  dNo           CHAR(2),
  PRIMARY KEY(cNo),
  FOREIGN KEY (cPNo) REFERENCES  course(cNo),
  FOREIGN KEY (dNo)  REFERENCES  department(dNo)
);

CREATE TABLE sc(
  sNo       CHAR(6)        NOT NULL,
  cNo       CHAR(6)        NOT NULL,
  score     INT,
  recordDate    date           DEFAULT current_date,
  PRIMARY KEY(sNo,cNo),
  FOREIGN KEY (sNo) REFERENCES  student(sNo),
  FOREIGN KEY (cNo) REFERENCES  course(cNo)
);

点击绿色箭头运行就可以自动建出数据表了。

下面插入数据：

mac postgresql创建数据库 pg数据库怎么建表_mac postgresql创建数据库_06

找到数据表，

然后右键单击图示标志

mac postgresql创建数据库 pg数据库怎么建表_服务器_07

熟悉的IDE，熟悉的操作，粘贴代码都懂的
