We Learn SQL #14 | Correlated subqueries with EXISTS in SQL

We’re going to talk about a new SQL operator named EXISTS, and how we can use it along with correlated subqueries.
If you want to learn or practice SQL, check out learnsql.com/.
Hello, I’m Adrian and this is another video in the series about SQL basics. You already know quite a lot about subqueries in SQL. In the previous video, we introduced correlated subqueries. Expand your arsenal with another SQL operator - EXISTS. Learn how to use them effectively and how to write better and clearer SQL queries.
Regardless of whether you are just starting your adventure with SQL or you are already an advanced user - I recommend our We Learn SQL channel and my short clips on the basics of SQL. I have recorded episodes about SQL JOINs, SQL Group by clause, and many more. Watch them and give them a thumbs up.

the information is clear but please do not ad music it's very distracting

[@shaistachattha8508]

I find your teaching method very helpful but the music keeps distracting me. Can you please remove the background music? Or at the least keep it very low.

[@Sumfinfunny777]

great video. Maybe lower the music volume a tad little? Just a suggestion

[@ank18]

I like your videos. They are easy to understand but can you please get rid of the background music. it suppresses what you are saying in the video.

[@TheProblembaer2]

[@shivamshekhar8027]

Stumbled upon your Channel today, and I gotta tell these are the simplest SQL videos out here.
Waiting for more stuff!

Thanks for the video. Could you please remove the background music and speak a bit louder.

[@anvarichn]

Writing this comment to complaint on too loud music - Hopefully that can be fixed!

[@faisalabdo4600]

the music dude !!!!!

[@hendrag1174]

Thank you very much Adrian for this great video which I think the best video regarding the Exists clause.

[@MagnusAnand]

Quick and to the point !

[@ajithshenoy5566]

the music is so annoying

[@stickercode]

I couldn't still get it. So , what is the real function of this exists though? If we, let's say remove it from your query sample, what will be fundamentally changed in the result set?

[@martajumi.inranbows3285]
