First 3 mins I got what I needed. Why are so many people averse to solid, clear examples? Phone book and book index very clearly defining how each index works. Thank you for this explanation, you are the man!
Very clear explanations with great examples. Better than the college professors I pay for.
Thank you very much! :)
You can say that again dud
i agree lol
TRUE, i was looking at their power points for an hour with a friend and couldnt understand shit and now i understand it with just this video
Bro...Yours is probably the best I could find so far. Good work !!
agreed... and he didn't even have to use any fancy animations, just straight up used 2 books.
Wow... we need more people like YOU in this world! - You actually KNOW what you are talking about, and WANT TO MAKE IT CLEAR to your audience. Man, THANKS! (I'm your new subscriber)
P.S. The great part about this video is that I will NEVER again forget the difference between Clustered and Non-Clustered Indexes.
The best explanation which I have ever seen. Thank a lot, man.
These are great. I could see a whole series called "Caleb Explains Stuff" (seriously though, you nailed it on clustered indexes, as well as on normalization). Good job sir.
Thanks so much man! Even after 6 years, your video is still the best out there
Great video! This really helps breakdown a somewhat complicated subject in a way that is easy to picture and understand. Thanks!
Hands down to the best index explanation that I've ever seen in my life. Thanks Caleb!
Dude.. you are awesome!
What everyone else said - excellent definitions and examples. I will be back for more as I am studying databases at the moment. You are doing a much better job than the lecture from a certain Irish university! (Yes, we have those. Don't mock!)
This is the first video of yours that I watch and I have to say I really liked it. Thanks very much for the explanation.
Best beginners explanation I've seen so far. Thanks man
It took me 4-6 videos before I landed on this one while trying to understand clustered and non-clustered indexes. This is all I needed. Thanks.👍
mate, you give the most summarized, simplified and elaborated lecture in entire youtube database.
You are a very good intelligent teacher.
You're such a great teacher. Thank you so much dude!
This has been such a helpful explanation of indexes. Thank you so much!
Man, I've tried to understand this sh*t for three days now, and you explain it for like 13 minutes :) THANK YOU!
I have an interview later today and this topic will surely be a part of the interview. You are the best, thank you so much!
Best tutorial I've ever seen! Thank you!
I find your educational videos extremely elucidating! Also, I love the traditional chalkboard setup!
Man.. absolutely amazing! Thanks a million. This is what I wanted to structure in my head for a long time shown in easy, friendly and funny way. Carry on! will go thru others
So well explained. Thanks mate.
I loved the analogy of the book index and a phone book to explain the Non-Clustered and Clustered indexes respectively. Good job dear Caleb!
I've been searching for the differences between Clustered and Nonclustered for half an hour and understood nothing until I watched your explanation. Thank you
most amazing explanation i've found thus far. thank you
One of the best explanations I have heard for a topic.
This is what i was looking for. Thanks bro 😁
Thank you! You're a lifesaver. Best video about indexes I could find.
Hi Caleb; You are honestly a very good teacher!
Loved the explanation . Thanks for clearing my doubts
Caleb, I have to comment one more time and tell you how impressed I am about your teaching style, I am impressed. Is it because I was brought in an area where teachers wrote on black-board? No it;s more than the noise of the chalk-piece, you just have a strange mix of enthusiasm, youth mixed with principled precision. Everybody is special but you are just a level higher, thank you!
always a simple and clear explanation. thanks man
Maaaan this video is great! Took me 10 videos to understand this concept. Appreciate the knowledge being taught in a NON BORING WAY!!! Great job
Very good. I really like the comparison of the two metaphors of a book index (non-clustered) vs. a phone book (clustered). When you compared the two, it all clicked. Thanks!
Great video great explanation. Better than anything I have seen. Explained and understood in seconds.
who needs college when we have CalebTheVideoMaker
Great video. This coupled with studying the syntax yourself is a great learning method. Very focused on the 'why?' of it all. Well done.
Really helpful man! Thank you for this!
Brilliant! You seem so young, still explained better than most old professors...
amazing explanation..crisp precise and very easy to grasp
best DB tutorial Ever!!! Thanks a lot
I wish all of my professors explained things the way you do, good work.
LOL 4:34 forEVER!! Great video! Very helpful, and I love this more relaxed style of lecture. Actually makes it fun to learn.
clustered - Key are sorted unclustered - Key-value pairs are in a Hash Map
seriously you explain very well thank you for the video
thank you, great explanation. keep teaching!
can't stop watching your Database related videos..you are the best I could find so far !
The best explanation I've seen re: cluster/noncluster. 1:42 says it all. Just got a new subscriber!
the best explanation ever I got on this topic
this is awesome .... superb explanation.. 😃😊👌👍👏✌ .... your tutorials special is, you explain the concepts with examples . it makes the students to get the practical knowledge ..rather than ... roaming around the books .... really good explanation.... it helped
Thank you for your explanation. I'm new to index although I knew about database. You explanation is clear and it's easily understandable by providing. examples.
Keep it up! So easy to understand.
Greatly explained, bravo.
You're awesome. Great teaching! Thanks!

Very good analogies. Spot on.
Very nice explanation of Clustered and Non clustered index
Excellent video. Thank you!
Very well explained. Thanks
Thanks for making this
Well I love this… Thank you sooo much
The best, I must have looked at 10 videos on this topic and you just nailed it 1) video is not in 480p 2) visual examples 3) SQL explanation But how do you use them in a query SELECT statement?
Interesting teaching, keep on!
amazing, thanks man
Those are really great analogies - ref: Index vs a phone book- thank you for sharing :)
Simply awesome.
this guy is the man
You are the worlds best teacher...
very good video , your pronunciation is very clear..I am Indian and whenever I refer any tutorial I only understand around 75% of words because of accent, but in your tutorial I have not missed a single word..what a great crystal clear accent :) .........create more videos I am very bad in database :)
best,........bro.thanks
You got a new subscriber!
Very good man!
Very nice explanation. You are really great..
very very well explained!! Kudo Bro
Let's say I have a table X which holds Column A, B and C with a non-clustered index on Column A. So this would create a non-clustered index with Column A as the lookup key and a pointer to the row in table X. If I make an update (not delete or insert) to a value in column B or C, this would not result in a change in the non-clustered index. If I make an update to a value in Column A OR insert/delete a row, only then the non-clustered index would need to be updated. Is this correct? Please can someone confirm. Thanks!
Ty, it was really helpful :)
superbb..thank you!
Thanks a lot !
Thank You
This plain English explanation just made so much sense to my 40 odd year old brain. Thanks
