Web Reference: This flask SQLAlchemy tutorial will show you how to update, delete and add rows in an SQLite3 database. It will also discuss how to properly query and search for entries in a table. In contrast to adding a new record, either deleting or editing an existing record requires your code to find a specific record that is already in the database. The record must be selected in a way that guarantees only one record will be selected. Flask, a lightweight and versatile Python web framework, simplifies the creation of web applications. This guide demonstrates how to implement Create, Read, Update, and Delete (CRUD) operations in Flask, complete with examples for building and managing routes.
