PostgreSQL入门

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：
点击确定就好了。
接下来建立数据库：
右键单击新建
名称随意。
接下来建立数据表：
同样右键单击
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：
找到数据表，
然后右键单击图示标志
熟悉的IDE，熟悉的操作，粘贴代码都懂的
