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.

Hello Sumit. Thank you for providing valuable course in tough times. I've followed few channels for SQL and it's always confusing because lot of other flavours of SQL are mixed with it. Hopefully I'll find out complete SQL course and be able to write easy to intermediate queries required for Data Analyst. Thank you again and very good luck to all the viewer's and subscribers of this course ๐Ÿ‘๐Ÿ™๐Ÿ™‚

sir when primary key is set auto-increment for id and we have a unique key for name ..why for each wrong value for unique key ..the primary key auto increment it self? like my id=1 if i give unique key two times wrong .then 3rd time i gave correct value as per unique key..now my id=4..why not id=2 or 3 because value was not inserted in db and they were wrong as per unique key.
