39. Base Transaction.py

# possible to provide a generic Python code for a base transaction as it heavily depends on the specific database management system and the operations being performed. However, here's an example of how a base transaction can be executed using Python's built-in sqlite3 module for SQLite database:

import sqlite3

# Open a connection to the database
conn = sqlite3.connect('example.db')

# Start a transaction
with conn:
    # Execute database operations within the transaction
    cursor = conn.cursor()
    cursor.execute('INSERT INTO users (name, email) VALUES (?, ?)', ('John', 'john@example.com'))
    cursor.execute('UPDATE users SET email=? WHERE name=?', ('jane@example.com', 'Jane'))

# Close the database connection
conn.close()

# In this example, we open a connection to an SQLite database and start a transaction using the with conn: block. Within the transaction, we execute two database operations: an INSERT statement that inserts a new user record into the users table, and an UPDATE statement that updates the email address of an existing user. Once the database operations are completed, the transaction is committed automatically when we exit the with conn: block.

# Note that this is just an example of how a base transaction can be executed using Python's sqlite3 module, and the specific operations being performed and the syntax used may vary depending on the database management system being used.
