What does the queryAll() function execute?

The queryAll() function in Salesforce is designed to retrieve all records from an object, including those that are inactive or soft-deleted, meaning they reside in the recycle bin. This function is particularly useful for situations where you need to retrieve a complete dataset, including records that might not normally show up in standard queries, which typically return only active records.

In contrast, other options do not accurately describe the behavior of the queryAll() function. For instance, it does not focus on finding duplicate records or aggregating data across multiple objects, as those tasks are handled by different functions or queries in Salesforce. The queryAll() function is specifically oriented towards providing a comprehensive view of all records within a specified object, making it a crucial tool for developers and administrators who require access to every piece of data, including those marked for deletion.
