Sample Program Code

To verify your MySQL installation, you can execute a simple program that connects to the database and retrieves data. Below is a sample Python script using the mysql-connector-python library.

Python Script to Test MySQL Connection

# Import the MySQL connector library
import mysql.connector
from mysql.connector import Error

def connect_to_mysql():
    """
    Establishes a connection to the MySQL database and retrieves the server version.
    """
    try:
        # Establish the connection
        connection = mysql.connector.connect(
            host='localhost',
            user='newuser',
            password='UserPassword123!',
            database='yourdatabase'
        )
        
        if connection.is_connected():
            db_info = connection.get_server_info()
            print(f"Connected to MySQL Server version {db_info}")
            
            # Create a cursor object
            cursor = connection.cursor()
            cursor.execute("SELECT DATABASE();")
            record = cursor.fetchone()
            print(f"You're connected to the database: {record}")
    
    except Error as e:
        print(f"Error while connecting to MySQL: {e}")
    
    finally:
        if connection.is_connected():
            cursor.close()
            connection.close()
            print("MySQL connection is closed.")

if __name__ == "__main__":
    connect_to_mysql()

# Import the MySQL connector library

import mysql.connector

from mysql.connector import Error

def connect_to_mysql():

"""

Establishes a connection to the MySQL database and retrieves the server version.

"""

try:

# Establish the connection

connection = mysql.connector.connect(

host='localhost',

user='newuser',

password='UserPassword123!',

database='yourdatabase'

)

if connection.is_connected():

db_info = connection.get_server_info()

print(f"Connected to MySQL Server version {db_info}")

# Create a cursor object

cursor = connection.cursor()

cursor.execute("SELECT DATABASE();")

record = cursor.fetchone()

print(f"You're connected to the database: {record}")

except Error as e:

print(f"Error while connecting to MySQL: {e}")

finally:

if connection.is_connected():

cursor.close()

connection.close()

print("MySQL connection is closed.")

if __name__ == "__main__":

connect_to_mysql()
