MySQL经典练习题-数据准备

-- 1、数据表准备：
-- --学生表---
CREATE TABLE STUDENT
(SNO VARCHAR(3) NOT NULL PRIMARY KEY, 
SNAME VARCHAR(4) NOT NULL,
SSEX VARCHAR(2) NOT NULL, 
SBIRTHDAY DATETIME,
CLASS VARCHAR(5));
-- ---课程表---
CREATE TABLE COURSE (CNO VARCHAR(5) NOT NULL,CNAME VARCHAR(10) NOT NULL,TNO VARCHAR(10) NOT NULL);
-- ---成绩表---
CREATE TABLE SCORE (SNO VARCHAR(3) NOT NULL, CNO VARCHAR(5) NOT NULL, DEGREE NUMERIC(10, 1) NOT NULL);
-- ---教师表---
CREATE TABLE TEACHER (TNO VARCHAR(3) NOT NULL, 
TNAME VARCHAR(4) NOT NULL, 
TSEX VARCHAR(2) NOT NULL, 
TBIRTHDAY DATETIME NOT NULL, 
PROF VARCHAR(6), DEPART VARCHAR(10) NOT NULL);
-- 2、插入数据：
