How do SQL Indexes Work

[@robertgoodberry]

I just realized indexes are like the signs in a hotel that help you find your room without having to search the whole floor. Thank you for the explanation!

[@paulo__vieira]

Good analogy.

[@Michael-e3u3o]

The motels have the non-cluster indexes for sure

[@Dennis_Wahengbam]

I have a better one but won't post it here...will post it on LinkedIn and watermark it so that people don't steal my idea and post it as their own...😅😅😅

[@bezaar7762]

[@abhishekkumar-sl8ow]

Hi Venkat, Thank you ! Only because of you I got the job as a SQL developer. I learnt a lot from these videos. God bless you....

[@Stelios.Posantzis]

Best short video on how indices work I've come across so far... This is great for a beginner.

[@danimrath]

Seriously the best instructor I've had.

[@capsonfernandes4803]

The way you use your talent to give back to society is incredible...Thank you so much for all the things that you do.

[@dodZeus]

Best explanation I ever received in 10 years of IT jobs. Thank you

[@starmole5000]

This is such a great video. It takes a single concept at a time and demonstrates it in a focused and clear way.

[@Suraaps1415]

My all time favourite, finally in DB development for almost 4 years and still following u and learning new things always.

[@tommyh3524]

You're a genius! I was literally wondering how does index work in SQL Server, then your video just popped up! Can't find other videos explain index better than yours, 100% thanks!

[@aagebadho6907]

What a dedication you have. You are a man of commitment and dedication. Hats off to you. I am following you since 4 years. Huge fan.

[@ashajyothi06]

Well said👌 Absolutely true🥳

[@ashajyothi06]

Plz highlight this comment

[@aagebadho6907]

@@ashajyothi06 indeed, he is truly a gem. There are many other KZbinrs who are creating many asp.net tutorial. But the moment I watched him, I thought that's the one. So since that time I started following him. He is really generous and humble I feel. If you see his details you will find that he has learnt a lot and now he wants to share his knowledge for free. He jas nothing to do with earning money from KZbin. He already earns enough.

[@123Rajjo]

Absolutely..! I have been following his videos too and each of them is just perfect! Can't find a better tutor than Venkat. Many concepts that I was unsure and unclear about, just got crystal clear after watching his videos. God bless him.

[@ashajyothi06]

@@aagebadho6907 your exactly correct 👏👏

[@teriyakov]

Dude, I've been learning from you my entire career. Thank you so much! I hope one day I can show my appreciation for all your hard work 👊😎🙏🙏

[@basilio100]

What I like in your explanations not "how", but "why". Thanks

[@rotan90]

I have two technical interviews for one company this week. Company has tables with hundreds of milions of rows. With that knowledge I cannot be rejected :D thanks man!

[@subhraz]

Venkat, I have read numerous blogs and watched many videos on this topic but I somewhere knew I didn't fully understand the concept. After watching this video, finally I feel yes THIS IS IT. Your explanation is priceless. Thanks a ton !!

[@shrusal92]

One of the best videos I have come across for CI & NCI, thank you!

[@SirigineediRavi]

Superb explanation. I have referred other videos but non of them given this much crystal clarity on Indexes. Thank you.

[@kapil4757]

I watched many other videos, those were either not useful or not covering the details to the fullest. Yo have exceeded my expectations. Thank you very much. Keep up the good work.

[@lasindunuwanga5292]

the example you showed by adding 1M data and retrieving one record blowed my mind. I was always thinking like how to test query optimization theories, it needs a large amount of data. This is the way. Thank you very much

[@jamrodhsingh2259]

I am really thankful to my friend who suggested me your channel. Why is it that I always come across people like you so late ??

[@kongwengseng3735]

OMG. I finally found someone to share this kind of SQL knowledge. Subscribed. ThumbsUp

[@yig8763]

Thank you Kudvent! The explanation is crystal clear! I like how you speak slowly and it makes easier to follow the mass media content now is too fast to catch people's eyes and make the majority into a stressed mode.

[@CRBarchager]

Always learn something new when watching your videos!

[@marspark6351]

Which video would I need to watch for 10:35 to learn about why we need the nested loop and inner join? Seems like we should just be able to return a row once we did a clustered index lookup

[@shafi123]

Brilliant Explanation for SQL Indexes ! Thanks Venkat

[@jeevant3406]

Just discovered this channel....got blown🤯 thank you Venkat✌️

[@F2H16]

What does the key-value pair contain for the non-clustered index? You said only @8:28 employee names are stored in the key values, which is not clear to me. The rest is quite informative.

[@pmshadow]

Wow, you are incredibly smart and give the PERFECT explanation! Thank you very much!!

[@rcasturi55]

Thank you Venkat. You are a great knowledgeable teacher

[@SaurabhSarang]

Thank you I always get confused and create unnecessary indexes for performance boost without reading execution plan.

[@martaminale3847]

Thanks so much! I would say you are such an amazing teacher for many folks.

[@nileshpatil5644]

smooth, clear and to the point video... awsome

[@curiossoul]

9:55 what does key value contain in non clustered index. What's the diff between k,v nodes and row locator nodes Also, why index seek shows scanned rows as 1 when db engine has to load whole page from disk containing multiple rows. Or does it exclude this from actual metric?

[@awilgedi5819]

You like the BOXER of Mohamed Ali of SQL server of all time. Thank you, Champ!
