  • 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.

    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.

    Think the output shown in video for "WHERE NOT EXISTS" is incorrect. It should fetch 2 values instead of 1. It should be "Magical Products" and "Amazing Stuff" as both of them have items less than 1 $

      You may have misheard the question, which was to find the suppliers that “do not provide ANY products more expensive than a dollar”
      “Amazing Stuff”, has a product called “Chewing Gum” that costs more than a dollar

    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?
