If you're looking to master SQL with real time usecases & looking to crack top product based companies, this tutorial is for you. Just follow through and you'll be able to write SQL queries in no time.
SQL, short for Structured Query Language, is a language used by software developers, data engineers, data scientists and anyone who works with data. With SQL, you can store data in relational databases and write queries to extract valuable information.
Even if you are someone who is working on SQL Server, Oracle DB, PostgreSQL or any other relational DB. Then you should be able to use your learning with hardly 5% syntax change.

sir from where we can download notes of these lectures
@@madhurajsingh9463 notes mile bhai ?
The thing that I particularly liked about your sessions is that you are teaching basic concepts but based on scenarios. Which will be more helpful to people.
Till now as a beginner and not from IT background, and having no prior knowledge of coding, I am able to understand things, hope it stays the same in future lectures also! Thanks a lot 💖💖👍👍
Hi Sumit sir, my name is prasad,
Your explanation is simply super and even non IT students also can easily understand
in this video, we learned below things
1 create table
2 simple inserts and multiple inserts
3 datatype mismatch
4 null values and default values
5 combination of null values and default values
Amazing, Very Helpful. Always Excited for next lecture.
Your sessions are really very easy to understand. Hard to find such content at no charge. Thankyou for taking your time out and doing this for your audience. Looking forward to further sessions. 🙏

Hello Sir,
I saw both of your videos and let me admit they are really really good. Easy to understand and then to practice!!
Frst of all thanks a lot for helping so many of us.
2 advices I would like to give :-
1. If you can tell us through the topic what questions are being asked in interviews from that topic, it would be really helpful.
2. Please try to include more topics in one video.
Again, thanking you Sir for doing this Noble Work for all of us 🙏🙏

Amazing sir
Even fresher like me is understanding
Happy to hear that you are able to grasp the concepts much easily.
Hi Sir, this is amazing 💯!Here's a small request for you to kindly cover more topics in a session.
Considering the huge audience base, I have tried to balance the amount of content in each session without losing out on the attention of the viewers.
@@sumitmittal07 agreed
Hi sir,I hope you are doing well,I just completed this video and I can say that your way of teaching is superb as you relate this basic topic with real world application scenario.I love your way of scenario based teaching.

Thx
this sql playlist is completely used for carrier in cloud computing
Thank you sir for this wonderful video.
Sir also i have a question that how can we delete a single row on a table?
Thanks sir for wonderful session again.
Keep watching and keep learning :)
Hey Sumit, Nice content. Just a small question
When you created the first record in employee table it too 0.14 sec to execute the statement and second record took 0.01 sec, why there is a time difference in execution of two statements. Thanks :)
Wonderful session. The way of teaching is very interesting
Glad you liked it, Keep watching :)
Well structured lecture presented thankyou sumit💞
Happy that you are liking it :)
I liked it
Wonderful session sir ..
🙏
Sir once again thank you for emboldening our careers. I have few questions to ask:
1) In case we need to store values in string data type and we want it to accept any lengths until 255 characters so that dynamically it can accommodate any lengths then can we write that?
2) Salary is something like private information, can we mask it while storing those values in database? can it be stored as a masked value? or we this encryption should be done in later stage?
3) while using insert stmnt, if again we declare the list of columns, can this list be different order, do we need to follow the order specifically? but yes while entering the values the order must follow the data types of the columns.
4) how to store values of different types, lets say for True I want to store 1, and false 0, can we use type cast and store these?
1. By default, when the length is not specified in the schema definition stage, it accepts any lengths until 255 characters.
2.This will be covered in the later sessions. (Dynamic data masking)
3. The values will be inserted in the same order as per the schema while creating the table. However, by listing the columns explicitly while inserting, the respective values will be inserted as per the order mentioned.
4. This would be covered later.
Follow along and you will learn all the necessary concepts of SQL.
@@sumitmittal07 Thank you very much for clearing the doubts sir :)
Best Regards,
Aditya
Thank you for sessions. How do you clear screen ?
Pls share link of entire series.....Thank you !
Hi sir, I am beginner at the end of the session 2 where you are explaining combination of null and default, after putting not null in location while creating table and if we insert manual null with inverted commas it is taking the value as null.
Just suggestion to insert records with single quotes -- eg) insert into employee values('Tamanna''s','R','Raju',31,35000,'chennai');
this way also we can go.
sir your lectures are very helpful.
It will be much more easy for us if we can get notes and query you write in session in discription .
I try to check if I can share the notes. Will do so wherever possible.
Hi Sir, Request to create a video on Data modelling and Schemas
Thank you for this series. Is it possible to share the document where you write all the queries ?
Hi Sir,
These sessions are really very helpful
But in session 2
CRUD operations "update" keyword is not used
For updating the the values in the table what keyword we have to use?
awesome session
Glad that you are finding the session helpful.
Hi Summit, what if I want to add NOT NULL constraints or default etc to the existing table instead of dropping and creating new table all together. Example there is a database and table in production and having data inside so I can not delete the table and re-create it else will loose the data but at the same time I want to add NOT NULL constraint as I just realised it now, then how can it do that?
This is one of the amazing playlist that I have ever found...💖💖🤞🏻🤞🏻
bro from where i can get these lecture notes please reply
@@madhurajsingh9463 I created the notes by my self.
Bakki courses bhi start kr do sir ,bigdata nd all types youtube pe sir ;)
The content and your way of teaching is really easy to understand .Where can I find your notes for quick revision?
Glad that you are finding the content easy to understand. I would advice to make notes alongside while watching the sessions.
Sumit sir do we need to drop each time table to update table schema, i have this doubts what if i have too many records which i don't want to remove and still i have to update table schema
