How to use Common Table Expression (CTE) in SQL Server to break down problems into multiple steps
In this SQL Server training video, instructor Peter Avila demonstrates how to utilize common table expressions (CTEs) to progressively convert one data structure to another. Using a real world example, Peter introduces a common problem in which the structure of the desired output and the structure of the data in the database are so different that the output cannot be obtained by a single transformation of the data from the database. Using a chain of CTEs, Peter shows how to break down the problem into smaller transformations and perform them step by step to obtain the desired structure in the output.
