How to Integrate MySQL with Flask for Efficient Database Access?

Integrating MySQL with Flask for Database Access

In Flask web applications, accessing a MySQL database can enhance data management capabilities. To facilitate this integration, we provide comprehensive code examples to guide you through the process.

Step 1: Package Installation

Begin by installing the Flask-MySQL package, which enables MySQL connectivity. Use a command like:

pip install flask-mysql

Step 2: Configuration and Initialization

To establish a connection with MySQL, configure your application with the appropriate credentials:

<code class="python">from flask import Flask
from flaskext.mysql import MySQL

app = Flask(__name__)
mysql = MySQL()
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_PASSWORD'] = 'root'
app.config['MYSQL_DATABASE_DB'] = 'EmpData'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)</code>

Step 3: Database Operations

Once the connection is established, you can obtain connection and cursor objects to perform database operations:

<code class="python">conn = mysql.connect()
cursor = conn.cursor()

cursor.execute("SELECT * from User")
data = cursor.fetchone()</code>

By following these code examples, you can seamlessly integrate MySQL into your Flask applications and effectively manage your data storage and retrieval needs.
