U are the best mentor and guide

A LOT going on in this lesson. Alex did a nice job of walking me through subqueries in MySQL. As the previous commenter suggests, I need MORE practice to really get these concepts embedded into the "gray matter" inside my head. At the very least, I intend to re-watch this video a couple of times without trying to keep up typing code, etc. I am getting a great deal of value from all of Alex's work. Thanks! 😎

Great explanations and options. Would have been better if you included the data file link to self-practice. Remember the best way to learn is learning by doing!

True. Having the dataset to work on would be way better than watching someone else perform tasks. Hopefully Alex reads your comment.

You can find the data files in the first video of the beginner MySQL series on Alex's channel.

You have to follow his course along the way. Alex used the file in the beginning as the teaching series.

Great!!!

Loving this series ! Thanks so much

Just when I needed to understand more about 'subqueries', this video came up. Thanks, Alex!

Great guy

Thanks alex for the easy explanation.. just a question, when you wanted to compare the salaries to avg salary, we also can use Partition by instead of s subquery right?

I thought of that in the first glance as well, but when you think about it you will find that "Partition by" will get you the average salary based on a criteria for example "Gender" but not the average of all the records. If you get another look at, let me know.

Thank you so much :D

I am currently learning sql and I am watching your videos especially the bootcamp ones. I already finished the videos for sql, is there any platform/s you can recommend to practice what I learned from the videos? I am kind of lost on how to practice these learnings. Thank you!

Hello Sir Ji Love You Hogaya From India 🇮🇳

I don't know if I missed it but does where you insert the subquery make a difference? If so, what are they so that I can better understand when I run into the need to use a subquery.

Microsoft SQL server and my SQL same or what plz reply sir ???

They are both Relational Database Managers but they are not the same. One is made by Microsoft and the other (MySQL) is open source.

select salary,(select avg(salary) from employee_salary ) avgSalary, case when salary>avgSalary then 'This employee is earning good' end as label from employee_salary ; when executing this code it says there is no column as avgSalary while I renamed the output coming from subquery as avgSalary, can we not use alias while comparing it with original column?

u shouldnt use case statement in the presence of subquery

Great video; I like how you take the time to inform your audience. Everyone wants to live a better life and be financially stable. By making the appropriate investments, living simply, and creating a budget, this is simple to do. Early in life, I discovered that hard effort is the path to financial independence.
