Suppose you're dealing with a complex database schema where you have a many-to-many relationship between two tables connected by a pivot table with additional columns. In such cases, if you need to update the value of a pivot column, you can use the updateExistingPivot() method.

For instance, let's say you have a subscriber table and a newsletter table, connected by a pivot table named subscriber_newsletter. This pivot table contains an extra column named status that indicates the status of the subscription. To update the status of a specific subscriber, you can use the updateExistingPivot() method, which allows you to specify the ID of the related record, the name of the pivot table, and the new value of the extra column.
