Want to connect **Flask with MySQL** in **Visual Studio Code (VS Code)?** 🔥 In this step-by-step tutorial, we’ll guide you through setting up a Flask web application and integrating it with a MySQL database. This is perfect for **web developers** and **backend engineers** looking to build dynamic, database-driven applications using Flask and MySQL. — ### **🔹 What You’ll Learn in This Video:** ✅ Installing Flask and MySQL in VS Code ✅ Setting Up a Virtual Environment in VS Code ✅ Installing `Flask-MySQL` Connector ✅ Creating a Flask App with MySQL Integration ✅ Running SQL Queries from Flask ✅ Performing CRUD Operations in Flask — ## **🔹 Prerequisites** Before starting, ensure you have: ✔️ **Python 3.x** installed → [Download Python](https://www.python.org/downloads/) ✔️ **MySQL Server** installed → [Download MySQL](https://dev.mysql.com/downloads/) ✔️ **VS Code** installed → [Download VS Code](https://code.visualstudio.com/) ✔️ **MySQL Workbench (Optional) for Database Management** — ## **🔹 Step-by-Step Guide** ### **1️⃣ Install Required Packages** Open **VS Code Terminal** and run the following commands: “`bash
# Create a project directory
mkdir flask-mysql && cd flask-mysql # Create a virtual environment
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activate # Install Flask and MySQL Connector
pip install flask flask-mysql mysql-connector-python
“` — ### **2️⃣ Set Up a Flask Application** Create a file named **`app.py`** and add the following Flask code: “`python
from flask import Flask, render_template
import mysql.connector app = Flask(__name__) # Configure MySQL Connection
db = mysql.connector.connect( host="localhost", user="your_username", password="your_password", database="your_database"
)
cursor = db.cursor() @app.route('/')
def home(): cursor.execute("SELECT 'Hello, Flask with MySQL!'") message = cursor.fetchone()[0] return f"[h1]{message}[/h1]" if __name__ == "__main__": app.run(debug=True)
“` Replace `"your_username"`, `"your_password"`, and `"your_database"` with your actual MySQL credentials. — ### **3️⃣ Create a MySQL Database** Log in to MySQL via terminal or MySQL Workbench and run: “`sql
CREATE DATABASE flaskdb;
USE flaskdb; CREATE TABLE users ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(100), email VARCHAR(100) UNIQUE
); INSERT INTO users (name, email) VALUES ('John Doe', 'john@example.com');
“` — ### **4️⃣ Run Flask App in VS Code** To start the Flask app, run: “`bash
python app.py
“` Visit **http://127.0.0.1:5000/** in your browser, and you should see **"Hello, Flask with MySQL!"** — ### **5️⃣ Fetch Data from MySQL in Flask** Modify **`app.py`** to display database records: “`python
@app.route('/users')
def users(): cursor.execute("SELECT * FROM users") users_list = cursor.fetchall() return f"[h2]Users:[/h2]" + " 8br 9".join([f"{user[1]} – {user[2]}" for user in users_list])
“` Restart Flask and visit **http://127.0.0.1:5000/users** to see database records. — ## **🔹 Who Is This Tutorial For?** ✅ Python & Flask Developers ✅ Backend Engineers Working with Databases ✅ Anyone Looking to Build Web Apps with Flask & MySQL — ## **🔹 Resources Mentioned in This Video:** 📌 Flask Documentation → [https://flask.palletsprojects.com/](https://flask.palletsprojects.com/) 📌 MySQL Documentation → [https://dev.mysql.com/doc/](https://dev.mysql.com/doc/) 📌 VS Code Download → [https://code.visualstudio.com/](https://code.visualstudio.com/) — ## **💡 Pro Tips for Smooth Setup** ✔ Ensure MySQL Server is **running** before connecting. ✔ Always use **virtual environments** for Python projects. ✔ Use **Flask-SQLAlchemy** for an ORM-based approach. ✔ If you get connection errors, **check your MySQL username/password.** — ## **👍 Like, Share & Subscribe!** If this tutorial helped you, please **LIKE, SHARE, and SUBSCRIBE** for more **Flask, Python, and Web Development** tutorials! 🚀 💬 Got questions?
