bookCreation Operations

Creation operations in SQLite involve adding new records to a database table. These operations allow you to populate your tables with data. Let's explore how insertion operations work within the context of database creation.

Inserting a Record

This code snippet uses the SQL INSERT INTO statement to add a new record to the "users" table, inserting values for the "username" and "email" fields. The data is passed as a tuple, and the query is executed with the execute() method to insert the values.

Be careful because this code considers working on an already existing table. If you don't have a users table in your database, then you need to create one.

To avoid the error, you need to create a table in the database with the name users and fields username and email. Only after that can you add records to this table.

Завдання

  1. Write an SQL query to insert a new record into the articles table. The query should insert values into the title, content, and author columns. Store the query in the variable insert_query.
  2. Use the cursor method to execute the SQL query with the data stored in the article_data variable.
