I have been using SQL for 25 years and Power Query since it came out in early 2012. And in this article, let me share my views on how SQL compares with Power Query. If you prefer to listen, check out the podcast episode – SQL vs. Power Query.

Power Query

All CRUD operations (Create, Read, Update, Delete)

Usually single source from a database or warehouse
(ex: SQL Server)

By default, you need permissions / special software to use SQL.

Almost anyone can use Power Query as it comes packaged with Excel and Power BI.
