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.
