How Indexes Talk To Each Other In SQL Server

In this video, I delve into the intricacies of how indexes in SQL Server communicate and interact with each other. Starting off, I discuss feedback received on recent recordings-mainly about my appearance and some audio quality issues-which provides a bit of a humorous backdrop to the technical content. The bulk of the video focuses on explaining how unique and non-unique indexes work together, especially within the context of clustered indexes. By creating two indexes on the 'users' table-one unique and one non-unique-and running queries against them, I illustrate the differences in query plans and explain why SQL Server behaves this way. The discussion then extends to how multiple nonclustered indexes can be used together, showcasing index intersections and unions, and how these operations contribute to efficient query execution.
