Java学生信息管理系统
系统分为管理员和学生两个身份
拥有增加，删除，修改，查询功能
基于idea和MySQL
附实验报告
可以参考如下资料实现
有具体需求可以找我再沟通，感谢
JAVA学生信息管理系统（数据库实现）
如有帮助，望采纳
-- 创建数据库
CREATE DATABASE niit
DEFAULT CHARACTER SET utf8mb4;
SHOW DATABASES;
-- 使用数据库niit
USE niit;
-- 创建表Student
CREATE TABLE Student
(
ID INT PRIMARY KEY,
NAME VARCHAR(4),
GENDER CHAR(1),
DOB DATE,
BATCH INT
);
-- 插入记录
INSERT INTO Student VALUES
(1,'张','男','1988-1-2',1),
(2,'李四','女','1988-12-3',1),
(3,'王五','男','1978-11-1',1),
(4,'若若','女','1989-2-5',2),
(5,'夏春','女','1998-4-3',2),
(6,'梅花','女','1999-12-6',2);
-- 查看表中所有记录 语法：select * from 表名
