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.

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

[@aritra1414]

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.

[@Someone-rj3vu]

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. 🙏

[@sumitmittal07]

Glad that you are finding the session useful :)

Awesome sir Very soon I will part of your big data course. Amazing sir Even fresher like me is understanding

[@sumitmittal07]

Happy to hear that you are able to grasp the concepts much easily.

[@poojasmriti7548]

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 🙏🙏

[@sumitmittal07]

Happy that you have found the series insightful. Noted your suggestions, will consider incorporating it in the upcoming sessions. :)

Thanks Sameer, that is really kind of you.

[@bipulmukherjee422]

Sir, the way you taught is so nice, easily understandable . sir in the very first of todays session you said that things will not work if you only watch videos. you have to practice it very well.. sir could you say in next session the from where we can practice and how to practice the things.. it will be very helpful for us.. Thanks a lot to make a session like this.

[@Sivasri2812]

Hi Sir, this is amazing 💯!Here's a small request for you to kindly cover more topics in a session.

[@sumitmittal07]

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.

[@mudaliarnaresh6519]

[@abhinavshaindilya674]

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 .

[@sumitmittal07]

I try to check if I can share the notes. Will do so wherever possible.

[@AdityaSharma-xh8tg]

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?

[@sumitmittal07]

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.

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.

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 :)

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?

Hello Sir, thanks for the SQL sessions. They seem to be absolutely helpful. I had one query related to Insert multiple tables: We can give the values for first,middle,last names and so on but what if there is one data where there is no middle name and we have inserted values as (first name, middle name, last name, age, salary, location). The one date which doesn't have a middle name will throw an error if we run it for multiple tables? Kindly let me know on this. Thanks 😊

u can assign middle name as a unique key for all tables .Second option set it as a default option -->A or B .Third set it as null while defining the table
