Many links, videos, teachers explain these concepts in such a complicated way, maybe because they want to show off their knowledge or intelligence by making it complicated and then explaining it. But you Venkat have made it so simple to understand and Digest, that I love watching all these videos. I think this world is a better place because of people like you who make complicated stuff easy.

[@georgewu5512]

[@pradyfunvlog]

sir i think there is a mistake in slide on time 15:57 ,there should be ..the NON clustered index has to refer back to the table as u explained on 15:05 to 15:35

[@asthatripathi9211]

thats what i thought

[@findmangesh]

I was about to mention the same. Thanks.

[@LeonaMeyer]

I agree. It should be changed. I thought I was going mad...

[@jag7450]

[@user-cv9ef5wu1p]

This tutorial is very helpful i've tried studying this but didn't completely understand the difference between the indexes , your examples really helped me understand thanx!

[@telugudevotionalspeeches8971]

Now only I got perfect idea about indexes. Thank you so much

[@Csharp-video-tutorialsBlogspot]

1. Yes, it is suggested to create a clustered index on a column that will be queries the most. 2. The column in the where clause should be included in the index. 3. SQL server uses unique index to enforce the primary key. So, if you already have a clustered index on a column other than the primary key, then a unique non-clustered index needs to be created on the primary key column to enforce the uniqueness.

[@Nikita12957]

As usual wonderful explanation Venkat Sir ! Just had one query ..can you please explain how can we decide which indexing should get used ?Is there any specific scenario ?

[@zheng-guangwang5112]

Hi, there might be a typo in the slide that summarizes the "Difference" between Clusterred and NonClusterred. Non clustered index has to refer back to the data table if the column is not found in the index. In the slide, it reads that clustered index has to refer back... is that correct? Thanks.

[@PravinKumar-qv9zd]

Yes, you are right...

[@syedrehanahmad7897]

Hey great work @kudvenkat. Guess what... i'm working for a database company and manager suggested me to see your videos to clear my basics of SQL Server. :)
