How to use sole() query builder in Laravel 8.23 ?

Introduction

With the release of Laravel 8.23,  ‘sole()’ method in laravel query builder is introduced, which retrieves a single record but has additional assertions.

Sole is beneficial once you need one row from the query and assert the query only matches one record. It’s advantageous once you expect one record but want absolute assurance that only one record exists. When quite one or but one record exist, Laravel throws an exception.

In order to make it more clear, Let’s check it out how we can use sole() method in different scenarios.

If we don’t have a record within the database table, we will expect the ModelNotFoundException thrown:

If we’ve quite one record within the database table, we also get an exception, but this point it’s the MultipleRecordsFoundException:
