I should have bought the lecture and listened to it, and I kept putting it off, but I finally finished it. Haha. Actually, I don't mainly deal with SQL, but I listened to it because I needed to know it, and it was especially helpful in the join part. I feel like I'm much more familiar with it now than when I first learned about joins?! Thank you for the great lecture. I'll come back soon for an advanced lecture. Haha.
