To be honest, everything was difficult while studying development... But the most confusing and hardest thing to approach was SQL. Join... Group By... Where... LIKE... and so on. There were so many things to consider that I was always intimidated... I kept telling myself "I should do it, I should do it," but I would give up quickly and just ask AI... I started watching this with the mindset of lightly checking if what I knew was correct since it was a short video. But I think I gained much more than expected. I was able to solidify the information that I only vaguely understood before. Fearful data manipulation... After watching this, I'm going to take courage and try other long lectures. Thank you for giving me courage. I didn't expect much from a one-hour lecture... but it was the best!
