I got tired searching through internet to find a simple explanation clustered and non clustered index. And my search ended with this video. Couldn't expect better. Kudos !
You are the best!! This is the easiest way to learn SQL that I have found. You are very clear, concise, and give real examples on how to use SQL. Thanks so much.
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.
You are generating lights in each home and family of a software guy... Because of Your explanation which we are living life right now... Thankyou so much.. Expecting many more videos from you
One of the best explanation about indexes. For non clusters index Christian song book, songs are ordered alphabetical order wher you can find the page number of the songs. Since songs are printed in topic order.
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
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.
it's the best tutorial for clustered index and non-clustered index I've ever seen. I can totally understand the definition through your lecture. thanks!!!
Great explanation. I had a few issues with this topic so far, but your teaching has eliminated those doubts. The examples you consider are very easy to replicate and the way you describe is really awesome. Again a big thanks for the excellent work which you have undertaken.
Hi venkat, Thanku very much for this vedio,I have searched so many articals about non clusterd indexes but still not understood.But this day after watch u r video, I have been understood fully about indexes,and it would be helpfull to me to go furthure into sql.once again thanku very much
Hi Venkat, In the differences slide, in point 2, could you please correct the statement "clustered index has to refer back to table" to "non clustered index has to refer back to the table." Thank you!
I enjoyed watching this video and I would suggest others to watch since topic has been clearly explained and also at the end there is an interview question was mentioned, which I experienced in my interview. Thanks a lot for educating the community.

@4:02 you talk about inserting rows of data where the ID is out of sequence. You mentioned that the table in the data is stored in sequential order by the ID. But how does SQL do that? 1. Does SQL do a sort on the ID field, after each row of data in the INSERT INTO statement?2. Does SQL insert all rows of the INSERT statement, then do a sort on the ID field?3. Does SQL insert each row of the INSERT INTO statement into the proper row of the table (thereby not using a sort on the ID field)?
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.

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
thats what i thought
I was about to mention the same. Thanks.
I agree. It should be changed. I thought I was going mad...
I did not catch the mistake, has that been fixed?
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.
Best Explanation on RUclips by far. Great Job!

Yes, we can think it that way. Smart thinking. Thanks for taking time to leave your thoughts.

This is explained clearly and perfectly.
very good video helped me with my mcipt sql 2008 , thanks bro fro your community offering
What a noble man 👏🏻
More info for those interested -
The keys of the index are internally stored as a structure ( B - tree ) that is associated with a table/view
@4:02 you talk about inserting rows of data where the ID is out of sequence. You mentioned that the table in the data is stored in sequential order by the ID. But how does SQL do that?
1. Does SQL do a sort on the ID field, after each row of data in the INSERT INTO statement?2. Does SQL insert all rows of the INSERT statement, then do a sort on the ID field?3. Does SQL insert each row of the INSERT INTO statement into the proper row of the table (thereby not using a sort on the ID field)?
Great content. This and part 35 really helped a lot. Thank you!!
Brilliant. Highly appreciate it!
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.
Yes, you are right...
There's a mistake at 15:58 point no.2
"Because the non clustered index has to refer back to table"**
Very clear explanation brother, thanks a lot!
Now I finally undertand! Thank you Venkat
Super super super super
You are a genious
Love you

Where are the index rows of a clustered index stored? Together with the data rows in the same data pages?
This is great, thanks Venkat!
Very good teaching. Can you post a playlist about advanced sql server.
Enjoyed your presentation...Gratitude.
Thanks..... from Peru.
