Usage

To setup this example, first download the example "Chinook" SQLite database and reference the corresponding schema diagram.

import os
import sqlite3

DB_FILEPATH = os.path.join(os.path.dirname(__file__), "chinook.db") # a path to wherever your database exists

# CONNECT TO THE DATABASE

connection = sqlite3.connect(DB_FILEPATH)
connection.row_factory = sqlite3.Row
print("CONNECTION:", connection)

cursor = connection.cursor()
print("CURSOR", cursor)

# EXECUTE QUERIES

result = cursor.execute("SELECT * FROM customers;").fetchall()
print("RESULT:", type(result))
print(result)

for row in result:
    print("-----")
    print(type(row))
    print(row)
