    Converting SQL data to JSON in Python is a common task, especially for web applications and APIs. This process involves fetching data from a SQL database and then converting it into a JSON format.

    Example

    Here's a simple example using SQLite3 and the json module:

    import sqlite3
    import json

    # Connect to the database
    conn = sqlite3.connect('test_database.db')
    cursor = conn.cursor()

    # Execute a query
    cursor.execute("SELECT * FROM cars")

    # Fetch all rows from the executed query
    rows = cursor.fetchall()

    # Get column names from the cursor description
    columns = [col[0] for col in cursor.description]

    # Convert rows to a list of dictionaries
    data = [dict(zip(columns, row)) for row in rows]

    # Convert the list of dictionaries to JSON
    json_data = json.dumps(data, indent=2)
    print(json_data)

    # Close the connection
    conn.close()
    Copied!
