How to Master MySQL CRUD Operations with NetBeans & JFrame | Insert, Update, Delete Tutorial (2025)

🚀 Want to learn how to perform Insert, Update, and Delete operations in a MySQL database using NetBeans, JFrame, and XAMPP? In this step-by-step tutorial, I’ll guide you through building a simple Java Swing application to manage a database using MySQL and XAMPP. By the end of this video, you'll have a fully functional CRUD (Create, Read, Update, Delete) system!

🔥 What You'll Learn in This Video:
✅ Setting up NetBeans, XAMPP, and MySQL for Java database connectivity
✅ How to Insert, Update, and Delete records in MySQL using JFrame
✅ Writing JDBC (Java Database Connectivity) code for database interaction
✅ Creating a Graphical User Interface (GUI) with JFrame
✅ Testing and debugging your CRUD operations

📌 Step-by-Step Process:
1️⃣ Setting Up the Environment

Download and install XAMPP (for MySQL server) and NetBeans IDE.
Start the MySQL database from the XAMPP Control Panel.
Create a new Java project in NetBeans.
2️⃣ Creating the MySQL Database & Table

Open phpMyAdmin and create a new database: crud_db.
Create a table named users with the following fields:
sql
Copy
Edit
CREATE DATABASE crud_db;
USE crud_db;

CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100),
email VARCHAR(100),
phone VARCHAR(15)
);
3️⃣ Connecting Java to MySQL Database (JDBC)

Download the MySQL JDBC Driver and add it to NetBeans.
Establish a database connection using Java:
java
Copy
Edit
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DatabaseConnection {
public static Connection connect() {
try {
Class.forName("com.mysql.cj.jdbc.Driver");
return DriverManager.getConnection("jdbc:mysql://localhost:3306/crud_db", "root", "");
} catch (ClassNotFoundException | SQLException e) {
e.printStackTrace();
return null;
}
}
}
4️⃣ Implementing CRUD Operations

✔ Insert Data

java
Copy
Edit
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import javax.swing.JOptionPane;

public class InsertData {
public static void insertUser(String name, String email, String phone) {
Connection conn = DatabaseConnection.connect();
String sql = "INSERT INTO users (name, email, phone) VALUES (?, ?, ?)";

try {
PreparedStatement stmt = conn.prepareStatement(sql);
stmt.setString(1, name);
stmt.setString(2, email);
stmt.setString(3, phone);
stmt.executeUpdate();
JOptionPane.showMessageDialog(null, "User added successfully!");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
✔ Update Data

java
Copy
Edit
public class UpdateData {
public static void updateUser(int id, String name, String email, String phone) {
Connection conn = DatabaseConnection.connect();
String sql = "UPDATE users SET name=?, email=?, phone=? WHERE id=?";

try {
PreparedStatement stmt = conn.prepareStatement(sql);
stmt.setString(1, name);
stmt.setString(2, email);
stmt.setString(3, phone);
stmt.setInt(4, id);
stmt.executeUpdate();
JOptionPane.showMessageDialog(null, "User updated successfully!");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
✔ Delete Data

java
Copy
Edit
public class DeleteData {
public static void deleteUser(int id) {
Connection conn = DatabaseConnection.connect();
String sql = "DELETE FROM users WHERE id=?";

try {
PreparedStatement stmt = conn.prepareStatement(sql);
stmt.setInt(1, id);
stmt.executeUpdate();
JOptionPane.showMessageDialog(null, "User deleted successfully!");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
5️⃣ Creating the User Interface (JFrame)

In NetBeans, create a JFrame Form with text fields for Name, Email, Phone and buttons for Insert, Update, and Delete.
Link the buttons to the CRUD functions.
6️⃣ Running & Testing the Application

Test inserting, updating, and deleting records from the MySQL database.
🎯 Final Thoughts
This tutorial gives you a solid foundation in JDBC and MySQL with a GUI-based approach. Now, you can extend this project by adding search functionality, validation, or integrating with other frameworks!
