Transcription of Video: Let’s take a look at another recursive CTE. That’s not looking at tables, but it’s just looking at math. And here, we could create a recursive function that’s called sum of parts, and select from the sum of parts. Basically, we’re creating a function that selects from itself. And what it does is it says give me …

Transcription of Video: One of the things I like play with is performance and pushing things to their limits. So what I want to do next is see how far can we push this sum of parts? Can we do the sum of parts for 40,000? With the option of Max recursion equaling 40,000? No, we cannot do that because …

Transcription of Video: Now on to recursive common table expressions. This is my favorite part. And this is where it gets really fun is working with recursive CTE’s. Because with recursive CTE, we’re doing things that are really difficult to do any other way with SQL Server. So, a CTE is considered recursive when the CTE references itself. It’s interesting, …

Transcription of Video: Every recursive CTE needs an anchor query. And what an anchor query is, is it defines the start of the recursion. This is the part that cannot reference the CTE itself, it has to start with some base starting point. So if you’re doing a hierarchy of departments, well, you’re starting the recursion may be giving me …
