In this video, we'll deep dive into set operators: UNION, UNION ALL, EXCEPT, and INTERSECT. Learn what they are, the differences between set operators and SQL joins, the syntax, how SQL executes them, and at the end, I will show you use cases on how I use them in my projects.
Set Operators are perfect to combine and compare results from multiple queries to do advanced data analytics and reporting.
