Delete operations in SQLite are used to remove records or data from a database table. These operations allow you to delete specific data that is no longer needed.

The primary SQL statement for deleting data is the DELETE statement.

python
Copy code

In this code snippet, the first line defines an SQL query that deletes a specific record from the articles table, targeting the record where id is equal to 1. The second line, cursor.execute(delete_query), sends this query to the database for execution.

Deleting Multiple Records

To delete multiple records that match certain criteria, you can use a WHERE clause in the DELETE query:

sql
Copy code

This query will delete all records where the author matches "John Doe".

Deleting All Records

You can delete all records from a table by omitting the WHERE clause:

sql
Copy code

This query will delete all records in the "articles" table.

These are the basic concepts for performing delete operations in SQLite using Python. You can customize your DELETE queries to remove specific data from your database as needed.
