Mastering Recursive Queries in SQL Server
Knowing how to form clear results from hierarchical data is vital for any SQL developer's career. This course will teach you how to create and optimize recursive queries that transform raw data into valuable insights.
What you'll learn
Hierarchical structures are among the most challenging datasets to query in SQL Server. Recursive common table expressions make the job easier, but they scare even the most skilled developers.
In this course, Mastering Recursive Queries in SQL Server, you'll gain the ability to create and optimize recursive queries.
First, you'll discover the two essential parts of a recursive query and an easy recipe to remember them.
Next, you'll learn to traverse some of the most common hierarchical datasets, including organizational structures and bills of material.
Finally, you'll learn how to optimize recursive queries for larger datasets by adding proper indexes and identifying when to skip recursive queries altogether.
When you're finished with this course, you'll have the skills and knowledge to query even the most complex hierarchical data and stand out in our data-driven world.
