SQL Tutorial for Beginners

In this step-by-step tutorial, learn how you can write your own SQL queries. You don't need any prior knowledge and we're going to use all free tools. By the end of this video, you'll know how to retrieve data from databases. At the end, I'll show you a neat trick to write some of the most complex queries with very little effort.
SQL stands for structured query language. It's a language that you can use to talk to your database. You can also use it to retrieve, filter, sort, combine, add, update, and delete data in a database. It's basically a language you can use to interact with the database. The great thing is that anyone can learn how to write SQL queries. You definitely don't need a degree in computer science. And once you know it, you'll have another superpower that you can use at work.

Hi Kevin. I'm a retired software architect with lots of experience of SQL, and only watched the video to see what you were presenting to newbies. I wanted to let you know that it's an excellent introduction to something many might be hesitant about. Great job!

For those who are following along and could not open the database diagram: Right-click "KCC" in the Object Explorer, then select "Properties". Under "Select a page", select "Files". Enter "sa" in the owner field and click "OK". The problem should be solved! I made a typo in my comment a year ago, where "sa" was "as" due to autocorrect. However, that comment has since helped a lot of you with opening the diagram. KZbin wouldn't let me edit my comment cause it returned error. Kevin, if you see this feel free to re-pin this comment.

[@udarexd4271]

To those who can not locate the KCC file when trying to add it in the Database. Copy paste or Move the File to the Backup folder which is located in Microsoft SQL server ---> MSSQL16.MSSQLSERVER ---> MSSQL. These files are located where you originally downloaded the whole software probably in Local disk C ---> Program Files. This will then automatically show the KCC file when you try to select it to add it in the Database like Kevin told in the video. Hope this helps.

Thanks for such a superb, easy to understand video. I'm new to SQL and never knew it was so beginner-friendly; your content was most helpful. Just 2 points I'd like to add for others who may be interested in checking this out too. 1. If you have trouble finding the KCC.bak file using Database restore, Goto SQL config manager and change the "Log On as" setting of the SQL Server to "Local System". 2. For some reason my Database Diagrams folder would not expand, couldn't figure out a fix, however the query design editor will show the tables & primary keys anyways. Thanks again!

I'm an old, mostly self taught DBA/Database-Developer that started working with SQL Server in 1998. I'm also a former Navy Instructor that wrote and taught a 200 hour course on microprocessors and how to program them way back in 1977 and have been teaching a whole lot of different things, including a lot of things about SQL Server and T-SQL. With that, I'll also say that I'm not easily impressed. And, with that being said.... You probably hear this all the time but now I have to say it. This is an absolutely brilliant introduction to SQL and SSMS and the order of revelation is perfect. Having put together presentations on the subject, I also have a deep understanding of, even with the best of tools, how long it takes to put to craft, crop, and publish a video of such incredible content. Very, VERY well done, good Sir.

For those getting backend database error when trying to load the database diagram, download the preview version for SSMS 19 and not the latest release of 18.12. If you already installed 18.12, uninstall it before installing the preview version 19. I guess the latest version of SQL is incompatible with the latest release of SSMS?

I am just starting to learn SQL and I have to say - that is the best course that I’ve ever seen covering what most view as a complex thing to learn!!! You gained a new follower!!

I'm about to get into an interview for a job that requires basic SQL knowledge, and this was really helpful

[@liamw6976]

I wanted to learn how to code in SQL for job opportunities because that's what 90% of applications require for what I am planning to go into. This video is unbelievably helpful, I just learned how to do decently complex tasks in 45 minutes with (albeit some struggle with the .bak file but otherwise) no experience. Thank you for what you do!

Im in the same boat. Any idea how you will tell them you will write on your resume that you know SQL? As we won't have a certificate or anything

[@maciejmarciniak-yx9sx]

Amazing! Thanks a lot 🙂 I've never thought I would be able to do anything with SQL and here we go! Looking forward for more 🤗

Hallo Kevin thank you for this video and making SQL look soo easy, by the time the video was coming to an end in my mind I was already telling myself how easy SQL is and when I started I was actually dreading watching the video because I have always said SQL is hard. Thank you for showing me that this is not as hard as I have been thinking and I hope to become certified in SQL.

[@DiegoDiazSunspots]

This is amazing! The way you explain everything it's so easy to understand. Thank you!

[@nimraali1523]
