Day 32: Creating a database

Introduction to SQL with Python

We're embarking on a new journey to master SQL with Python, leveraging the power of the sqlite3 library. Our first step is to create a database using the connect method. This handy function serves a dual purpose - if the database doesn't exist, it will create a new one; if it does, it will connect to the existing database.

Setting the Context

For the purpose of our upcoming tutorials, we'll imagine we're running a bookstore, tracking books, orders, and customers.

What's Next?

In the subsequent videos, we'll dive deep into various SQL commands essential for managing your database. So, stay tuned!"

And here's the corrected code snippet with headers:

Importing Necessary Libraries

import sqlite3

Connecting to the Database

# Connect to the bookstore.db database
conn = sqlite3.connect("bookstore.db")

Creating a Cursor

# Create a cursor to execute SQL commands
# which acts as a pointer to the database
# connection
cursor = conn.cursor()

Executing SQL Query

Please note that you need to replace "SQL query" with your actual SQL query.

# SELECT all columns from the books table
cursor.execute("SQL query")

Fetching and Printing the Results

# Retrieve all rows returned by the SELECT statement
rows = cursor.fetchall()
# Iterate over the rows
for row in rows:
    print(row)
print()

Closing the Connection

conn.close()
