I have only experienced CTEs in Alex's RUclips lessons. I believe I will learn more when I use CTEs out in the wild. Reasonable pace with clear instructions. I feel challenged in Alex's courses but NEVER stupid. We all have to start somewhere and it's helpful to have someone showing me the way that has walked this path. Much gratitude for your efforts Alex. Cheers! 😎
Data analyst freshers really wants you
Dont stop making videos
Using ctes constantly at my work, a senior colleague thought me once, they are very helpful for huge data sets to compare with each other
I have started your data analyst bootcamp. I have completed your entire sql, excel series with projects. Now i am learning Tableu. Still to go with power bi and python.
Thank you for bootcamp series
What SQL server do you use?

This is the best way to go on tables. Thank you for this information
Superb!!
I needed this as I'm currently learning CTE!!
Great lesson and the next one on #Temp tables will be too. Last week, one first round interview question (non technical part of the interview series) I was asked was "describe the difference between a CTE and a #Temp Table." Alex basically answered that in this video.... Gotta be ready to answer these types of questions on the fly. 🙂
Hello my friend. I love your content. You keep going
Hey Alex! Love the video on CTEs. I'm wondering if you'd consider making one on solving a gaps and islands problem? I've watched and read tutorials on them and the overview logic makes sense but I tend to get a bit lost when applying all the various window functions. Thanks!
Thanks you sir 👍
Thank you.
hi alex,
we need end to end project data analysis
please consider about it..............................................
Alex what is the difference between VIEW function and this WITH CTE example stuff
May I ask in which real-world scenario would getting an average of averages without weighing by their relative counts make sense? I know this was just a didactic example, but I was still a bit puzzled by that considering the fact that an actual population average would have to consider how many people are contributing for each average: ((avg_salary * count_salary) WHERE gender = female) + ((avg_salary * count_salary) WHERE gender = male) / the sum of both counts. Thanks in advance!
Sir can u help me with this project " Efficient multidimensional modeling for educational data analytics"I didn't find any videos related to this on yt😢😢
I have noticed that the result for avg salary for both female and male is different from the result obtained with windows functions, on the pervious video. Could anyone explain, please? which version is more accurate?
Hey, I see the same in both cases, female 53750 and male 57428.5714. Which results do you see?
does anyone know where I can find parks_departments table ?
I had to create one myself. Probably you do same
@@abdulqudusoyelami3019 you can download it by the link at the first SQL-video for beginners "installing mySQL" :)
Check his first video (select statement video) you will see the data set link in description
Can chat gpt do this?
easily, but it still does silly mistakes, so you gotta be able to verify the output
"Can you create a small single sample temporary data set and from that give me SQL query that joins two CTE's together?" plug this question into your CHAT GPT machine and see for yourself. As stated above it does make mistakes sometimes if not asked the question properly OR not given enough context.
