It's official! The Socratica Python Kickstarter was a success! Thank you to all of our supporters. Because of you, many more Python videos coming soon!! 💜🦉
You guys are amazing, the quality of videos and the actress in the video is at par with a professional TV show or a movie. Excellent explanation as well !!!
She deserves an Emmy's for the quality content production. Fantastic scripts, visual and sound effects, and best actress. Love the (7-min) interlude of classical music, hilarious you. Totally loving this! Thank you Socratica, you really are awesome and indispensable!
Whoever writes these scripts deserves an award. As well as this lady for delivering the lines perfectly and giving this great performance. Education and entertainment at it's best.
I have 20+ years in data analytics and IT and this is one of the best videos on indexes I have found. Thank you for making this so educational and fun at the same time! I'm excited to check out your python channel next!
@joncrosby1, Since you have 20+ years of experience, could you please guide me how to get a job in this field? I am a Computer Science graduate and want to go to Data Analytics (I dont want to be a hard core programming developer). I have learnt SQL, Basics of Python and Data Visualization tools like Tableau and also made some dashboard to learn properly. I need your advise on how to apply for data analytics job. Should I learn any more skills? like data warehousing or cloud? Please let me know. Thank you in Advance!
Maaan, I graduated college 3 years ago, learning from all kinds of tutors and lecturers, but never like crazy Cyber Doctor here. I feel scared, and educated
As Ulka said at the end of this video, use indexes wisely! A general rule of thumb for indexes is that adding indexes to a table will speed up selects (that are constructed correctly) and slow down inserts/updates/deletes because whatever SQL system you use has to rebuild those indexes if a modifying transaction occurs.
I remember a query that ran over six hours. Ever month again year after year. One day I checked the output and that query had run only a few minutes. I asked a colleague if there was a problem. She said 'O, i created an index.....'
At last, I can understand mySql. Explained perfectly in a way my brain can comprehend. I will definitely be donating to keep you guys going. Thank you so much.
Unbelievable! The best SQL tutorial I have ever watched. It couldn't be shorter and clearer. I bet even a child or even my grandmother could be able to understand it.
wow! This video worth a lot. B4 watching this i never knew index is this essential for faster performance. Well explained. Keep uploading such Videos. Animation were superb to understand quickly. God bless u.
ur such a life saver, i often dont understand immediately in class but those videos make me understand almost immediately, thats quality, appreciate it, wish ppl always invested this much time in teaching
I found this UA-cam channel some time ago when I was first learning python and have been laughing ever since. I learn a good deal of important information here about methods/functions I thought I knew already. Its fun and informative and I hope you continue to educate me in this most hilarious fashion.
Great video! One tip: Adding indexes to a table will speed up select commands but will also slow down other commands like insert/update/delete because the SQL server has to reconsider the indexes if any kind of modifying transaction occurs in the future.
Incredible. I've spent seven hours over the past two days refreshing myself on database concepts and filling in gaps and this was my favorite 10 minutes of those seven hours by a factor of 100 billion.
WHAT A BLAST!!!!! I watched the whole tutorial, took notes I was literally hooked learnt a lot felt like watching a movie, the production and creation of this course is PRICELESS THANK YOU , wish there was a JavaScript course like this
I don't think any educational material has been as entertaining as this playlist I just watched... It's mind blowing!... Totally the best investment of my time!
WOW My jaw is on the floor at how amazing this video is! Quality, tone and speed of voice is on point. Explanations are well thought out and provide all necessary context to comprehend. Video/Audio editing is perfect with just enough to keep it interesting and remove distractions.
Love how you're insisting on reading out all times in milliseconds like a programmer, even though the GUI already has converted it into more human digestible seconds and ms.
Fantastic. I'm slightly familiar with SQL because I only very occasionally need to have certain data pulled by our DBAs. Very cool @ 7:25 - I had that question. Thanks Socratica.
I have never seen anyone make sql this interesting, am literally watching things i already know and use almost on a daily, but literary enjoying each and video.
You should show query planner to illustrate how RDBMS determines which query plan to use. I'm guess that is already on your list of things to cover. After that, you should cover lock escalation under concurrent load where you have a mix of reads/writes on the same table. Then for the advanced SQL indexing concepts, compare b-tree versus bitmap indexes. If you get to report queries materialized views versus dynamic views for complex multi-dimensional queries :)
I've been looking for a tutorial for days that solves all the doubts I had before starting to use indexes, and this one definitely succeeded. Thank you very much! A fairly complete and well explained explanation!
Fantastic job girl... Well explained... We learn the most when we are having fun... And you have successfully turned SQL into fun.... Love the craziness
what about : SELECT COUNT(*) FROM person WHERE last_name = 'Mohanty', AND first_name = 'Ulka'; Result: ONE! and only ONE! Messages: Successfully run. We found the best teacher in earth and mars! Total query runtime: 0 msec.
My SQL professor's professional bias leads him to gloss over basics and assume we know them. Your videos are fantastically helpful. If I could portion off some of my tuition to you, i would.
I always think of this video when I create a clustered index. This tutorial very plainly outlines the benefits of indexes and how they can speed up our queries. Thank you!
This is quite a goofy video but at the end I learned everything I needed unlike from watching other videos on this topic by different content creators. Thank you for such a great video.
26 years in web development and I've never found a video tutorial, book or talk that explains what's happening under the hood when table indexes are created and used. That was a great video but the mystery continues. Does anybody out there have a clue what's going on under the hood with table indexes? PS, thanks for the video. It was really good.
I first encountered your videos when I was learning python in the beginning of pandemic lockdown. The python videos are sarcastic and engaging. Thank you.
Cool video, found it randomly :) Just to add: Too much indexes on a table can make INSERT-operations slow. And: Indexes need to be reorganized periodically as they get fragmented when new data is inderted into the table.

Wish you the best. You are awesome.
Please continue SQL video series with more SQL concepts. Big fan :)
I thoroughly enjoyed the 596,000 ms spent watching this video.
The hardship is impossible to put into words...
But it lasts over 900000!
You might want to re-check that.

You just made databases interesting, and 10 mins ago I never even realised what an index was!
This couldn't be easier, crisper and more interesting. Simply enjoyable!!

Hahaha that's brilliant 😂
How many entries and coloumns did the tables in the database had ? 6 hours seem crazy.
It took an year to get a solution for a slow running query.. ? 😂

I love the enthusiasm, robotic fast (not boring) narration, clear and practical examples, and the visualization! Definitely subscribing!
Unbelievable! The best SQL tutorial I have ever watched. It couldn't be shorter and clearer. I bet even a child or even my grandmother could be able to understand it.
I can't believe a video on sql has quarter million views. That speaks to the quality of this video
This is the channel I ve been waiting for long time. Thanks UA-cam algorithm.
Love the comedic way you use to teach. Please, do not stop doing it!!
I'm a professional that spends all day querying and this is the first video that explained it concisely
10 min ago I never thought learning can be funny and interesting at this awesome level. Good job.
This is the best coding channel I HAVE EVER SEEN!!!!!!!!!!!
I can't believe i watched the video. i learned something. and totally enjoyed every second of it.
The reason why this channel hasn't hit a million yet beats me. It should have 10 million subs. The lady is very entertaining

Must Amazing SQL Tutorial ... You Deserve More Than A Billion Subscribers
This was great thanks! Just had a query that was taking 2 minutes to execute. I added in about 9 indexes and it now runs in 2 seconds. Gamechanger!
Love how you're insisting on reading out all times in milliseconds like a programmer, even though the GUI already has converted it into more human digestible seconds and ms.
It's to make it sounds that it really takes a lot of time because 4000 is bigger than 4.
you have no idea, how much you have helped me.. i have no words to say thanks .. it changed my whole DB speed .. thanks million ..
Fantastic. I'm slightly familiar with SQL because I only very occasionally need to have certain data pulled by our DBAs. Very cool @ 7:25 - I had that question. Thanks Socratica.
This lady is on another level. You have taken UA-cam to another level
I love this series. Keep up the great work!
I have never seen anyone make sql this interesting, am literally watching things i already know and use almost on a daily, but literary enjoying each and video.
You have no idea how happy this makes us! 💜🦉
Just fell in love with you after hearing your laughter.
Gotta say this is the clearest examples I've ever seen
woooow really interesting and the way of her teaching and animation was awesomee....upload more videos on sql ,clear explanation ........congrats
Yes finally a decent video that is in English and understandable for human beings
I really appreciate the effort you've put in the background sounds nd editing thereby making it very interesting.
This is one of the best computer science videos I've seen in my career (I'm final year 2 at uni) and whole life also, you rock!
one day machine will talk like human, human like machine
The way teach or explain, Its best.
Concepts just penetrate into mind.

Straight to the point unlike other tutorials. I only needed the concept really..
all in RAM
EVERY SINGLE COLUMN...YESSS! xD
Not a big deal.

The professors at our university can learn a lot about teaching from you! This was awesome
Fantastic job girl... Well explained... We learn the most when we are having fun... And you have successfully turned SQL into fun.... Love the craziness
First, I really think these videos do a great job of teaching their lessons. Second, I really appreciate your commitment to the bit.
Could you please tell the Socratica to make new series of topology, or any high math
Have to say that this is the only video I have seen that makes SQL seems fun to learn. Thank you!
what about :
SELECT COUNT(*)
FROM person
WHERE last_name = 'Mohanty',
AND first_name = 'Ulka';
Result: ONE! and only ONE!
Messages: Successfully run. We found the best teacher in earth and mars! Total query runtime: 0 msec.
Did not expect this level of enthusiasm; not a complaint.
Thank you for such an amazing explanation. I have one question though, the index you created was that a clustered index or a non-clustered one?
My SQL professor's professional bias leads him to gloss over basics and assume we know them. Your videos are fantastically helpful. If I could portion off some of my tuition to you, i would.
Extremely helpful video, thanks
Best tutorial series on SQL
HANDS. DOWN.
One of the greatest explanations I've ever seen! Well done!
