@Luka Larry it worked and I now got access to my account again. I am so happy:D
Thank you so much you saved my account!
@Bridger Enzo happy to help :D
Man, I watched like 6-7 video tutorials about Join in SQL. Your is the only one that I understood. Great explanation!
Same with me!)))
me too!
me too bruhh
Totally agree with you!
facts
And I thought Joins were advanced concepts in SQL that I'm not yet ready to understand. God bless you Mr. Blue
Create View Transactions AS
Select tbl_customers.Customer_ID, FirstName, LastName, Address, OrderDate, tbl_payments.Quantity, tbl_product.UnitPrice From tbl_transactions
INNER JOIN tbl_delivery ON tbl_delivery.Delivery_ID = tbl_transactions.Delivery_ID
INNER JOIN tbl_customers ON tbl_customers.Customer_ID = tbl_delivery.customer_ID

Great video! I got a much better grasp on SQL Joins in 18 minutes than I did in my instructor's 2.5 hour lecture. Thank you, sir!
Great video. The graphic and audio quality made this very easy to learn.
Clear tutorial ! I cannot understand why the others make this topic hard to understand :) Especially the tiny tables you use, allows us to clearly observe what is happening
I love your pacing. Not too fast or too slow. You're right in the goldilocks zone!
Congrats, two years later and continuous amazing. I can understand everything with your videos.
This is the best SQL join explanation I've found on RUclips. Thanks for your concise and understandable tutorial.
Goodness, he is the only man who makes sense when it comes to explaining confusing joins, really good. Thanks
This is by far the most helpful video I watched about Joins. So simple and straight to the point.
Thank you so much for this video! I've watched so many PowerPoint presentations and lectures and your video was the only one that actually helped me understand joins! Thanks again
This was hands down the best SQL join tutorial I've ever seen in my life! Keep up the good work!
I have been trying to understand JOINS for the past hour and these 18 minutes broke it down perfectly. Thanks for your clarity!
I just started using SQL yesterday, and I already have a much higher level of understanding than a few of our developers, thanks Joey! Great series of videos!
Hands down the BEST SQL tutorial on JOINs that I have seen! Makes clear sense!
This dude is the Michael Jordan of SQL vids.
LMAO
Finally a tutorial that made things simple and makes sense! Thank you!
Thank you Sir! You have made learning about Joins so simple. I spent hours reading through text books, trying to figure it out, and in less than 20 minutes you succeeded in making it clear to me.
Spent an hour reading various tutorials and watching videos on this. Then you saved my nerves.
This is by far the best and easiest explanation to SQL Joins I've ever seen, I can't thank you enough!
Literally the most straightforward video I could find, thank you so much. Now all those joins make perfect sense. 🙌
One of the best examples of how 15' video beats hours of manuals, lengthy presentations or, God forbid, expensive classes. Much appreciated.
I have to agree! After hours of what should be a simple straightforward just simple explanations I FINALLY hit your page! Well done sir!
Joey, all of you videos are super easy to understand. The visuals are great and you do great with the audio level. So many people upload videos where the audio is so low you can't hear it or it sounds like it's recorded in a box. Thanks for doing what you do.
Many people post tutorials that are just confusing, yours is very clear Thanks Joey
Read 1-2 paragraphs from 3 different books in 2 mo. on joins. Today I said I'm going to get it. I come home, 18 min later, I'm good. Locked in. THANK-YOU-MR.-BLUE!
he is a GOD.
great man we owe you a lot, great explanations, great teacher!!!First I was learning without the app installed and I couldn't understand a thing, then I installed the Microsoft sql and I learned all your tutorials, I even created those tables that you show them in that video alone to understand better... Your are the best! thanks a lot.
Just stopping by to tell you - this is a great resource for folks who are new to SQL OR for developers who are trying to level up on SQL skills. Thanks for taking the time to make this!
Thank you Joye your voice is so calm and relaxed to listen too. This is extremely helpful.
Finally a dude with a clean microphone, no stupid music and animations. I have been really rusted on sql, since I don't have that much experience either, this helped me a lot and I also learnt something new that you can filter ON clause and also you can use a where after the join.
After a long time came here to have a quick glance about joins. videos from other channels was confusing. But your was much clear. Thanks a lot Joe.
The Visual representation of the joins as Venn Daigrams helped a lot. Thank you!
As so many other people have written, your clear, paced explanation with demonstration really helped me solidify my handle on these basic concepts. I'm subscribing. Thank you for your efforts.
I always thought this is hard, and I've never tried to learn this. After watching this video and trying it out, it's actually pretty simple and very useful! Thank you!
This really helped. From reading to watching other tutorials. This one was broken down perfectly and easy to understand thanks!
Thanks Joey..Really a simple and the best way of explaining Joins..The best part was the picture where you have shown putting the real tables in it and explaining it which has made it much more easier.Have tried so many videos to learn the concept but hands down you are the best..
As someone has said in the comment section, I have watched several videos to get a good grasp (concept) of the SQL joins, in my opinion this tutorial is the best tutorial I found. Simple, clear and to the point. Many thanks & God bless you!
Jesus, Thank You! I've used so many different sources and No one made it as straight forward as did you. Thank you :-)
You are the best teacher/instructor EVER!!! I dont know how you do it, but you make learning SQL so easy and enjoyable! Thank you!!!!
Awesome! Straight to the point! Correct and excellent explanation!
Well after completing two courses on linked in learning and watching like 10 videos on RUclips, I finally understood how to formulate join query and why do we use that = sign.Thank you so much for the clear, simple explanation!
Exactlly the thing I need:
1. No BS agenda
2. no fancy context description
3. just thing about the topic and pitfalls I may encounter.
Congrat, another good vid tutorial found!
The clearest description of joins I've ever seen.
You are brilliant sir! I understood the concept of inner join as soon as your wrote your fist query. Thanks a lot !
Special Salute. I went on with google for hours. In just 8 minutes you cleared all messed up things!!. Great Job. Thank you.
The best explanation of SQL joins I have ever come across! God bless you.
Thank you! This is very helpful in my work. I am truly appreciative to have your videos to go to over and over as I need them!
i have been watching so many videos to understand this concept, yours is the only one that makes it so simple to understandable. Thank you so much
Thank you for this! Especially how you connected code with picture, made things really clear!
Good job. Finally... a video that clearly explains this topic. Thanks.
god. this helped me so much on my assignment. I was looking at numerous videos and i couldn't understand any of those until i see yours. I'm so glad that this video exists. thank you so much.
This was the best explanation of Joins. I appreciate you so much! other videos gave me an idea but this really helped me to comprehend and grasp the content. Thank you so much. You breaking this down step by step made a world of difference.
It only took me 12 years to understand joins. I was always afraid to touch this topic. Now I have some confidence. Thanks.
Now those diagrams finally make sense. What an excellent way to teach us joins!
Thank you Mr. Blue. You succinctly explained in 8 minutes (didn't have to watch the whole vid) what my classroom teacher failed to teach in 45. More power to you, good sir.
Thank you for your in-depth explanation for novices like me. Really appreciate it.
I'm now more confident after watching your videos. Great teacher indeed.
I wish I had a teacher like you in my school. God Bless You!
Where has this dude been??!!! I have been developing for over 10 years, and I found this explanation to be coherent and clear as I was looking for a refresher on my SQL skills.
thank man
Thanks for explaining it very clearly. Out of all the videos that I watched regarding this topic, only yours made it all sense to me!
Thank you, this is so helpful. I couldn't understand my teacher, your video is 100% clear and on point. I literally have no questions. Really appreciate it. The quality is great too. I never thought that could be an issue in 2021, however, after viewing my teacher's recordings I realized that one must put an effort to make it this good.
I always had an idea of how the joins worked and usually experimented until I got the desired results. Now I fully understand the technique!!! Thank you Joey!!!!! :)
Good job JB! I've felt like an idiot watching and reading my teachers instructions on joins but after your video I feel like its clearer. Mostly because you explain while showing the queries.
The way he explains it is so clear. Really well done
This was the first video I saw of Joey's SQL series, and I must say I'm hooked. I was going to watch the 1hr beginning video. But, I'm very glad I watched this one first. Extremely helpful and look forward to watching all the videos in the series. Just a tip for anyone who is new to T-SQL (Microsoft) or SQL in general. I would personally practice the JOINS he talks about. And even come back, and watch the video a couple times to really help it stick. Again amazing video thank you!
Dude tomorrow is my DBMS exam for my diploma and you've probably saved my life. Hats off mate.
Thank you for your great explanation, only this video showed me what each Join do. Bless you
Your explanations were very simple. Great video!
Hi Joey, this video clarified a lot of my confusion on how to do Joins. Thank you for your help!
I can't agree more with a comment, "Your is the only one that I understood". Same here. Absolutely brilliant explanation. Thanks so much Joey for making this awesome vids. You are the hero in SQL.
Best explanation about SQL joins on the Tube. The others try to over complicate things to make themselves sound scientific which defeats the purpose of a tutorial. Thanks Joey.
good lord that is so much more simple than what WGU teaches in their SQL class. you just saved me from so much friggen confusion
I like how simply you explained this. Was the exact video I was looking for. Thanks a bunch!
Brilliant tutorial. You were right on the spot to explain about this topic. It was really easier to understand SQL joins thanks to you
thanks for explaining. it is very clear and understandable than any other video i watched so far
Nice! Straight to the point on SQL JOINS and the explanation is very clear. Thank You!
This is probably the best Join video I've watched. Caleb should watch your videos for production values inspiration!
for real, this is the best tutorial on JOINS..Great explanation, thanks!
Thanks a lot!
This short video summarised hours of my database classes.
Totally recommendable! :)
Thank you! I always find myself getting lost when people started talking about 'coding' or 'programming'.but your video is so well explained, and I understood what you have taught us. maybe i am not too dumb after all.
really great, clear, and easy to understand explanation. The best I've seen. Thank you!
My tutor took us through a one hour lecture on joins and a one hour classroom session and all that she did was confuse me hugely and make my head spin! You made this so simple and easy to understand. Thanks :-).
using the venn diagrams to explain the concept was genius. Thank you for your great tutorial. thumbs up
Lovely video Joey. This was quite helpful
Nicely done!. The Venn diagram explanation really helps to clarify the various Join meanings.
Thank you, this was very easy to fallow and easy to understand. Also the graphics really helped understand the lef, inner and right joins. Great job!
Thanks Joey for this clear and concise tutorial. I learned basic concept of SQL
This is the first time I understand these stuffs. THANK YOU
Great video. Presented clearly and at a pace, I can understand first-time. Thanks.
Dear God, I was looking for someone who explain me how to use joins, and finally You sir made it clear and simple. Thank you!
After a long long time of procrastinating to understand the joins, finally, thanks a lot
That was great explanation! Thanks a bunch, Joey! :)
Finally, I get it! Thank you, so simple now.
Really well explained, it definitely helped me understand the different types of JOINs. Thank you.
thank you so much for this, I don't think I would be able to the thing I wanted without this
I struggled alot with joins.. and now im like "thats it??"

Your vid is amazing! I never understood joins Until ur vid taught me how to do so
40 minutes before my exams, you saved me ! Thanks !
Perfect! The venn diagram makes it so much easier to understand.
