问题描述：编制一个学生籍贯信息记录簿，每个学生信息包括：学号、姓名、籍贯。实现功能： 1、创建信息链表并以磁盘文件保存 2、读取磁盘文件并显示输出所有学生的籍贯信息 3、按学号或姓名查询其籍贯 4、按籍贯查询并输出该籍贯的所有学生 5、能添加、删除和修改学生的籍贯信息 6、显示输出湖北籍和非湖北籍学生的信息并可分别存盘 知识点：文件打开，保存，结构体，搜索，链表说明：其中1－5功能是必须要实现的功能。

这个问题属于计算机科学的范畴，我可以帮助你回答这个问题。对于这个问题，你可以使用C语言来实现一个基于链表的学生籍贯信息记录簿。首先，你需要定义一个包含学号、姓名和籍贯的结构体。然后，你可以使用链表来存储所有的学生信息并将链表保存到磁盘文件中。接下来，你可以实现按学号或姓名查询学生的籍贯，按籍贯查询所有学生，并能添加、删除和修改学生信息的功能。最后，你可以编写代码来显示并分别保存湖北籍和非湖北籍学生的信息。

该程序使用了一个结构体来存储学生信息，并通过一个数组来存储所有学生信息。程序实现了输入学生信息、读取磁盘文件、查询学生籍贯、添加、删除和修改学生信息、分别显示上海籍和非上海籍学生信息、浏览所有学生信息、按学号排序等功能。

用代码实现学生籍贯信息记录簿(使用数据库) 编制一个学生籍贯(到省一级就行，不用到市)信息记录簿，每个学生信息包括：学号、姓名、籍贯。功能要求： (1)按学号或姓名查询其籍贯； (2)按籍贯查询并输出该籍贯的所有学生； (3)能添加、删除和修改学生的籍贯信息； (4)籍贯从JComboBox中选择

好的，下面是使用Java语言和MySQL数据库实现学生籍贯信息记录簿的代码示例：

首先，我们需要创建一个名为“student”的MySQL数据库，其中包括一个名为“student_info”的表，该表包含三个字段：id、name、hometown。

创建代码如下：

CREATE DATABASE student;

USE student;

CREATE TABLE student_info (
    id INT PRIMARY KEY,
    name VARCHAR(20),
    hometown VARCHAR(20)
);

接下来，我们编写Java程序来连接MySQL数据库，并实现查询、添加、删除和修改学生籍贯信息的功能。

        panel1 = new JPanel(new GridLayout(3, 2));
        panel1.add(label1);
        panel1.add(tf1);

        panel1.add(tf2);
        panel1.add(label3);
        panel1.add(hometownBox);

        panel2 = new JPanel(new GridLayout(1, 4));
        panel2.add(btn1);
        panel2.add(btn2);
        panel2.add(btn3);
        panel2.add(btn4);

        add(panel1, BorderLayout.CENTER);
        add(panel2, BorderLayout.SOUTH);

        btn1.addActionListener(this);
