Late to the party, but... In your first example, your termination clause was "n < 10" and yet, you got 10 in your results. Can you explain why that is? Fantastic video! Thank you so much. This really helped me understand (except the termination clause lol)
I think it's because when it gets to the 9th iteration, 9 is still less than 10 and the query is selecting 9 + 1 for that iteration. The results include 1 because 1 is the "seed" value that is also being selected with the first select statement.
How are recursive ctes evaluated? I was hoping for step by step approach. What does union all have to do with anything? Shouldn't anchor statement be called multiple times when recursive statement is called?
Probably the most simplified explanation of recursive CTE,
Thanks a lot sir, keep the good work n stay safe.
Thanks! I appreciate that!
I had no clue about RCTEs even after various tutorials but you really simplified it for me. Thanks a lot.
My pleasure! I’m glad the video made it easier for you to understand recursive CTE’s
very helpful video. perhaps the simplest explanation out of all the videos out there! Thank you so much!

Thank you, you're great! You helped me a lot! I finally got it!
Glad I could help!
Thanks for the video! How would you introduce a recursive starting at 0 and going by .125?
That was extremely helpful. Thank you much!
Glad it was helpful!
Awesome!
Thank you, very helpful.
Great video, really helpful, Thanks 👍
Glad it was helpful!
Great video, thank you!
If using MySQL the syntax is
WITH RECURSIVE
That for pointing that out! I find it interesting how each "dialect" is slightly different.
@@EssentialSQL thank you so much for the video!
