Somebody (or some process) might change something in the database concurrently, and even two changes that you executed consecutively might not have consecutive timestamp values. To make sure that nobody has changed a record in the meantime, you might decide to update it like this: asp.net core qr code generator GERADOR DE QR CODE NO ASP . NET CORE - Érik Thiago - Medium
