In this tutorial, you'll learn how to use SQL using mySQL. First, you'll learn what SQL is and the different relational database management systems. Second, you'll learn to install mySQL in your computer. Third, you'll learn to import a real database for you to practice.
Then we'll get into writing queries. First we'll write simple SELECT statements, then SELECT with DISTINCT, and eventually aggregate functions such as COUNT or AVG. We'll then move on to filtering using the WHERE statement. Following that we'll learn to GROUP BY, ORDER BY, and even add a LIMIT. Finally, you'll learn to export your query scripts and results table and importing it into Excel or Power BI.

Please make a playlist to teach us SQL from beginner to Pro,thanks man
Please make a full series, this was so helpful!
Hey Kenji, thanks for the video
Just started learning SQL recently.
Really enjoyed the video. Definitely looking forward to part 2. Thank you
Great content. Love the way you simplify difficult topics in a short time. Thanks Kenji
Really enjoyed this! Would love a Part 2
thank you! I'll keep it noted :)
So well and patiently explained! Thank you, Kenji!
plz make full series on sql
Thank you so much Kenji, your channel is very resourcefull...you make it as main reference for everyone to learn data analyst
you are so smooth in explaining, awesome content
Wow, Indeed Beginner friendly, the demonstration is direct and enough to start learning SQL. Thank you.
Kenjii you are so smarttt, please upload a second part!!
Hey man, your videos landed me an offer, just wanted to thank you
Great, Thank you! plz make full series on sql.
Dang! This is so good. Your course looks way better than the courses on Coursera. Looks well thought out and very practical with a fun set of data to use.
SQL video so great!! very clear explanation.
Really enjoy your data analysis content
Hopefully you'll make a tableau tutorial
I watched several videos about sql, also took a course on Udemy. The course was great, although I have to say Kenji explains everything VERY SIMPLE and STRAIGHTFORWARD!
Please teach everything, you are doing it very very very well!
Great tutorial - thanks a lot.
Thank you so Kenji
Please with part 2. Very enjoyable.
Very concise, very informative and saved me a lot of time. I appreciate the effort you put into this and I have subscribed and liked.
Marvellous sir
Your 15 minutes video played a vital importance of SQL pls upload 2nd part. Thanks sir
Thanks again, Professor!....
Thank you!
Cool! will wait for part 2
You are the best, you are born to teach🎉
I know this question is going to come up for beginners. SQL is way better than Access as it is used to handle larger datasets. Now, will learning Access prior to SQL help you, sure but it won't make learning SQL any faster. However, if you learn SQL first, your access learning will be much faster and easier. So which should you start with? Go with SQL if you are looking for career growth and you wanna play with the big boys. For small companies with smaller data sets, Access should be fine. Hope this helps anyone looking for it. And as always Great videos from Kenji.
this was great! very good video! totally new to SQL, but a wiz at excel formulas pivot tables and the like so this was very familiar. i wonder if there is a listing or database of operators that we can refer to when building formulas to query off of. thanks!
Could you make a video on overall formatting and margins in excel from beginner to advanced? Thank you and love your videos.
I'd love to see you make videos on Python as well. You always provided us with the best content.
Totally agree!
Thank you
Really enjoyed the video.
Hello, thanks for the video, it is an amazing video as usual. I am eagerly waiting for the part 2 of the SQL video.
Really helpful!!
Thank You
I feel like I can really learn this wow you’re a great teacher!
Lets go! Best of luck :)
Really enjoyed the video. Would love to have more of these type of videos
Part 2 on Sunday :)
Thanks a lot man. I'm studying Software Engineering in University and having exam from this topic. Helped a lot!
Awesome and best of luck my friend :)
Yes, we definitely want part 2. Also I wonder if there is a way to connect API with MYSQL, such as Amazon Sellercentral or Walmart API
Would really love to see a full series on this, I am willing to pay for it as well, you can maybe release 4-5 out of the 10 part series for free on youtube and the view access for the rest can be members only.
Would be interesting to see a comparative analysis between SQL and Power Query and which one is the best
Superb❤
Love it
Hii Kenji, First of all great video.
Thanks for sharing!!
Had a question, all these things we can also do it with excel then what is the real use if SQL?
Can you clean up on power query?
Will you make SQL projects for data analysis
Your are good.
Wow thank you
You’re welcome 😊
Plz part 2 🙏🏼🙏🏼🙏🏼
can't. really import ,, there's a pop up that says: Unhandled exception: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128) 😫
Best..
perfect
Good day, can you create a playlist for SQL please ?
Great! But how do i download SQL for Mac OS?
Make more videos on sql
Im very new with sql and i have a question. Why do we use SQL while we can easily do it in Pivot Table.
size and complexity: Pivot tables can become cumbersome and slow with very large datasets
I agree with @satheeshkumar9586.
But you asked a good question though.
Hi can't find the file in the description
Make more videos in SQL
Is Power query similar to SQL?
Good good damn got me feeling like I know a lot now lol 😂
An intermediate video would be greatly appreciated as well. Thanks 😅
Make a sql playlist
yess plz
I can't access the database/dataset used in the tutorial
I am just wondering, how hard is it to master SQL? I struggled with programming in college especially C++. Coding is something that I find it very challenging.
I’d say it’s simpler than c++ and other programming languages but a step up from Excel/excel formulas
@@KenjiExplainsThank you. I went through Excel, Power BI course and started the VBA course you offered. SQL is also something that I want to learn.
That's awesome! I'd say compared to VBA it's about the same difficuly (perhaps even a touch easier than VBA)
for some reason my files are not opening when i select download save
same , im using macbook m1 ... idk why , i'm completely beginner with mysql 😥
Font is small! I can`t see
Hi,can you help me?
Mysql is a free software ?
Please Kenji I did not see the link for the file
its in the description like i mentioned

I have been trading for about 6 months now and just about every mine, it backfires and slaps me in my face. Nearly impossible for me to catch more than a few points I try to do top down analysis but it doesn't work for me . I say to myself, clearly I'm in the 90% that lose money, so I open a demo account, do my analysis, then take the opposite of what I would normally take and get the same result. I'm starting to feel hopeless, any advice for a struggling trader?
Indeed, the recent market downturn serves as evidence that a vast majority of individuals lacked a sufficient understanding of the underlying financial dynamics at play.
Don't listen to him, don't give up. Mining takes time(months, even years) to master, even the pros learn everday. Never the less, if you lose money no matter which side you take, maybe you need to look at how you are managing active trades rather than how you are entering them. My advice, find a mentor . And also, try incorporating the use of oscillators, Bollinger and pivot points into your strategy. And most importantly move to higher TFs(4h or 1D preferably), you'll thank me later.
You're absolutely right. While I don't incur losses with every trade, my primary challenge lies in allowing my winning trades to fully develop. I often find that I miss out on significant movements in the market. Instead of capitalizing on these opportunities, my trades tend to reverse after initially moving in my favor. Additionally, I acknowledge that my entry points could be significantly refined. Finding a mentor to guide me through these challenges would be immensely beneficial, although I recognize that locating a reputable mentor is easier said than done. If you happen to know any legitimate mentors, I would greatly appreciate any recommendations you could provide.
I've been working with a financial advisor since I started investing. In today's market, the challenge lies in timing purchases and sales of trending stocks, which seems straightforward but can be tricky. My portfolio has grown significantly, making about $1500 bi-weekly. Essentially, what I'm saying is that the 5% of consistently profitable traders often fly under the radar; they're typically low-key individuals. I rely on my account manager to handle entry and exit orders for me.
Would you mind recommending the specific professional you utilize for their services? I'm facing numerous marketing challenges and could use some assistance.
🙌
Cheers!
Where is upload file link
In the description like I mentioned
Mr Kenji, u have 13 dots on your face. Nice..
Things change with time.1996 I wanted to learn sql but nothing was in my range.no quality tutorials,no help,very limited internet connection and much more.
Now there are high quality fast connections,fast laptop but i am an old person and it doesn't stimulate any more.
Why would someone use sql over excel
Coz sql can handle huge amounts of data Excel can't.
Second
lol
Yeah, I get this is for people with no background, but honestly, click-click-click through the installation steps is a bit unnerving. I think you should have at least a rudimentary explanation of what you're doing and what's being installed and configured. If something dies during these steps or a user needs to troubleshoot something, they're pretty much hosed if they don't know what's going on. Thanks,
first
XD
fetched data for billionaires not shown completely why?
thank you. Great video!
Thank you for watching!
plz make full series on sql
