SQL Joins Explained |¦| Joins in SQL |¦| SQL Tutorial
SQL Joins let you fetch data from 2 or more tables in your database. We will cover the more common types of Joins: Inner Joins, Left Joins, Right Joins, and Full Joins (also called ‘Full Outer Joins’). We will introduce these 4 kinds of Joins and prepare you for our next video where we will cover many examples.

never seen such a well-produced SQL video
Your style is simply hilarious. This is what great education should look like!
Let's not only acknowledge the great tutorial, but also the satisfying sound effects when the rows are joined together! 🥰

I really deeply appreciate that you explained this with a theme, because I know how much time and effort editing this kind of videos take. You could just simply explain joins in a whiteboard or a regular presentation but you went beyond that and that alone deserves recognition 👏👏👏

Gotta say, this is one of the most creative ways to teach SQL and databases I've ever seen.
Watched an hour ago, still laughing. You managed to make SQL funny while explaining it better than anything else I've found so far, and that's gotta be a superpower of some kind.. You guys are awesome!
Your explanations are simply clear, straight to the point and easy to understand - better quality than majority of university professors or boot camp trainers. Thank you

Amazing! You just saved me 2 hours of reading, thank you.
This is absolutely a masterpiece. I usually don't comment on videos but THIS VIDEO??? I cannot pass through without how amazing and well done this video was made. I was completely lost when I was reading about the Join process, and most videos usually don't help as much. This video was not only informational but also very fun to watch. It was kind of like watching a movie. Once again, thank you to everyone who contributed in this. Subscribed.
This is unironically the *best* explanation of joins in SQL that I have come across. Thank you so much for making this video!
In the future, everyone uses SQL still? Oh, god, this truly is the worst timeline.

Don't worry. The SQL will also be encapsulated by a layer or AI. I mean... sure... the AI will probably also plot to vacate all of Earths atmosphere or something, but at least you wouldn't actually have to write the SQL yourself anymore.

The Venn diagram example nailed it into my head wonderfully. Thank you. Now I cannot unsee the types of joins.
This is probably the weirdest tutorial i have ever watched, but it is absoloutely amazing and well explained.Thanks!
OMG........this lady is amazing! The production values, comedic values, learning values, and creativity of the video are just killer. I never had so much fun watching a SQL video before and that does put a smile on my face.........

By far you've explained joins as best I've seen on YT. Using inner join as the standard and left, right, and full as different tools it helps add context for why you would utilize the joins. So many times people try to explain this stuff completely theoretically, and does my head in. I enjoy the quirkiness too
FINALLY!!! Someone who has explained joined in a way I can understand. Thank you 👏🏾👏🏾
wow....never thought I would find SQL remotely interesting.... Thank you for making this so much less painful!
I usually don't login to the youtube. But, after hearing that "join" joke I had to subscribe and give you a like.
Dang so far the best video explaination for beginners ive seen on youtube. Thanks.
Yo... just me or is this the most creative way to learn this stuff? They killed this!
finally SQL tutorial that visually demonstrates and explains how rows from different tables are joined.
A SQL query goes to a bar, walks up to two tables and says, "May I join you?" Great videos Socratica!

Started weird (but in a good way) and ended up being maybe the best programming tutorial I've seen.
Ulka you are one of the greatest teachers i ever saw in my life! no joke
You just saved my brain... Thank you for breaking this down the way you did. I could not figure out the Join was actually doing but your formatting and starting with the * for all columns then narrowing it down made it all click for me. Thank you so much!!
The background noise giving that outer-space vibe is such a nice touch. I thoroughly enjoyed this video.
This is by far the BEST EXPLAINATION of Join in SQL. Thank you so much!
Those animations are just superb. I have been looking for something like this that will give a clear visual explanation of joins but they are very rare to find or not good enough. Thank you Socratica
7:53 love it 🤗 This was extremely clear. Much love to the editing too
The visual clarity of this tutorial is amazing! I've struggled with joins for weeks, this was just what I needed. Mil gracias!! Sad for pour homeless John Carter though...
By far the most clear and concise explanation of JOINS I have seen! Thanks so much!
I'll be watching these more in detail at the next semester
Maybe your next series can be about teaching some "words" in English language, which can help us express how much we love this series !
This is one of the best explanations I've ever seen! Tears of join running down my face right now.
This style of teaching makes the pieces of information much less painful to learn. I love it! Thank you so much for this content!
I can't tell how these animations took my concentration, everything went easier than I thought, Thank you Socratica for your clear explanations and time, I can't wait to be where others are🥰.

This is a really great video (and I assume course though I've not seen the other videos yet). Super clear explanation, and I love that I can use my imagination to help to solidify the concepts better, great job!
I didn't there was any way in the entire multiverse to make SQL entertaining but you did it! Now I'm starting to understand JOINs!
I just want to let you know that you've spoiled me. I'll never watch another unenthusiastic programming tutorial without wishing you were teaching it. Thank you for actually having fun while teaching!
It's good to know that I live in a world where glados 2.0 will patiently explain sql to me.
Good to hear that the crazy NoSQL fad has ended and we're sensibly using SQL in the future. ;)
THIS IS EXACTLY WHAT I WAS LOOKING FOR, the tables so nicely presented instead of starting at sql server no clue what to type omg
I have tried to get clear information on JOINS from a few certs, and this is 1000X more clear than any of them, and quicker. I am SO thankful for this
It's worth noting that PostgreSQL also has a USING clause for joins, which can be used in place of the ON clause when--and only when--the column(s) being joined on in both tables have the same name. So using the example in the video, "ON b.base_id = m.base_id" could be replaced with "USING (base_id)". And yes, that syntax would work for all 4 types of joins.

Yup. Unfortunately, there are a lot of DBMS's that do not USE USING, so it wouldn't work in code trying to be portable across DBMS choices.
Writing this down in my notebook: Okay, yeah this makes perfect sense. Everything is logical and clear. Testing myself with creating a customized sandwich database: What is what again?

This might be the most creative and fast forward tutorial I've ever watched !!
I wanna go back to college again and make perfect my exams.
Just found this channel, it's really good, although sometimes the face expressions are kind of creepy, maybe that's why I like it hehe
Just the right amount of interesting, visual, and quirky/goofy. 12/10 would recommend.
extremely helpful, finished my assignment and didn't cry once because of this. 10/10 gives you maidens.
I bought a bunch of books and none of them use Venn diagrams like you did here. I could have saved a lot of scratch. : /

This video has a 90s sci fi retro gaming vibe... I would spend 100s of hours watching lectures if they were delivered like this
Never knew sql tutorials can be that Perfect.
I think the writers were having too punny of a time with this script. However, she could read the dictionary and I'd still watch and learn. Join is one concept that is vital in a relational database, yet it is the weakest of my SQL skills. Thank you for producing this course.

Never thought I'd be smiling through a programming tutorial... just brilliant stuff
My prof spent an hour, and he succeeded in confusing 80+ students in the lecture. You spent 10 min, and it makes so much sense!
I didn't understand SQL join until I watched this video. Thank you so much. Amazing socratica
This is the best channel...ever...I love how she is like a character from a TV series...It helps people like me who has a short attention span focus
literally the most relateable video ive seen on joins. ive been doing databases for about 10 years never had to use joins until recently, i could just write code and extract with seperate queries. or use aliases and take values and insert a function. sometimes you need to extract one value from one sql without furthersteps. thank you so much im not even finished the video and feel like i can go back and conquer the world lol
This is by far the clearest explanation of joins that I have seen. Thank you and we'll done. It motivated me to *JOIN*
OMG i almost didn't click on the video and thank god i did. the environment you created and the theme of the video is a genius way to set example. the way you talk and the straight-forwardness of the points you send across is just perfect. thank you for a GD amazing vid.
I already understood this topic in the first few minutes but I couldn't stop myself from watching till the end. I never knew I could actually enjoy a tutorial. I'm checking out the rest of your videos
Best description of SQL joins I've found on youtube. Great content. Thanks
This has to be the best, most creative and engaging explanation video on KZread. I'm impressed.
Whimsy, quality content, brevity, this playlist is the complete package. Absolutely love the effort!
The sense of humour is golden! love it!
This reminded me of old naff educational videos from primary school, except, it was BRILLIANT and hilarious and very educational. Excellent satire and very informative. Kudos to you at Socratica!
This is an ACTUAL LIFE SAVER. Thank you for making a fun, silly example, and ACTUALLY VISUALLY MOVING THE ROWS and COLUMNS physically in the space to join them. I NEEEEEDED to SEEEE this. Not to HEAR it explained in fancy tech terms. You are AMAZING.

I've been a data analyst for a whole year and was missing this basic visual explaination of how JOINs work. You helped me figure some duplication stuff out I was really struggling with. Thank you!!
And those light hearted wits are spot on. A tech savvy person like me is enjoying this thoroughly. I cracked at "maybe the other databases will..... JOIN us..".
This is just incredible. Its very clear, keeps you interested throughout the whole thing, has intentional bad jokes, kudos @Socratica
As a visual person, that venn diagram explination made it click instantly! Thanks!
Wow, by far the best produced and most entertaining database and/or tech in general, tutorial I've seen in a long while!
