Unpivot Columns to Rows in SQL Server (SQL Detailed Walkthrough) 

In this video you will learn how to unpivot data using SQL Server via a highly detailed example. We will use Tableau Superstore data to build an aggregation table using a CTE (Common Table Expression).
Aggregation tables are useful to data visualization developers as table information is stored with pre-summarized totals at a higher level of aggregation than the most granular fact table. They allow reports to be generated from small, rather than large, tables. The UNPIVOT relational operator enables this benefit!
