This is a very good option if you are committed to completing multiple training and certifications in a year. Coursera certificates really matter and can give an edge to tour resume.
This is an excellent way to generate date range, however, I don't know if it would work in PostgreSQL/MySQL. A question was asked to me during an interview where the Recursive CTE was to be used. The question was to find the number of Sundays in the month of August 21. I didn't know how to approach it then, but Recursive CTE along with DATENAME function would have done the job.
This tutorial is amazing! For example, with the auto calendar, given that there's the DECLARE statement at the beginning, is there a way to turn this into a View so it can simply be run when needed? Or, must it be a Stored Proc? Thanks.
I have a usecase as below There are n number of nodes connected to each other, Every output link of a node matches with the input link of another node I have to make them join based on inputlinkid and outputlinkid But the challenge here is I don't know how many nodes a flow has , so I have to create columns dynamically where each column represents a node name. Can you please help me how to create dynamic columns while running recursive cte
hello there, god bless your efforts..I have a simple enquiry as new sql learner. How are CTEs different from temporary tables? Thanks for taking care of this.

Brilliant! Best video on this subject!
Glad it was helpful!
Very helpful! Thank you for breaking it down. This was exactly what I needed to understand CTEs. :)
Glad it was helpful.
Great topic. Superb explanation. You deserve more subscribers !
Thank you 🙏
very clearly explained and excellent examples. Looking forward to more detailed videos like this 👍
Thank you. More full course videos coming soon!
Great video! Exactly what I was looking for to refresh myself on recursive ctes. Your videos are always helpful. 🤗
Thank you so much
Thank you! Great case with hierarchy!
Thank you 🙏
At 13:04 stream time, Please let me know why output has "Z" included when we already mentioned ""< ''Z" " (should this not exclude "Z")?
excellent video.
Thank you
excellent explaination
Glad it helped
Thank you so much

Very helpful. Thanks.
Thank you 🙏
Hi Ma'am
By using of this cte .
I need rows starts like this type so how to do it..
001,002,003,...010,011,012,013,...,100

Thank you for sharing the scenario. We will cover it in one of our upcoming videos 🙏

Stored Procedures are best for this type of code.
Thanks for this
Glad it was helpful 🙏
So, it's basically a while loop but in SQL format. I've been wanting to find out how to do for loop or while loop in SQL for a very long time! Thanks!
Thank you
Great explanation, can you please give information regarding semicolon in CTE
Thank you. You can check out the video below - It has important tips about CTEs.

How are CTEs different from temporary tables?
Thanks for taking care of this.
CTEs are not physical tables. They are temporary result sets. Temp tables normally refer to temporary physical tables created in tempdb database.
Please make a video two parts 12 minutes
Sure, will be posting shorter videos as well 👍
