These videos have an intrinsic cost of about $1000 to make so if you enjoy them, please consider donating so that I can make more videos on a more regular basis! It's not just standing up and talking. It could be weeks of planning/research, then multiple takes, then hours of editing then responding to comments. Don't forget the thousands spent on the equipment used. I've spent a lot of money on the equipment I use to shoot/edit these and when they fail (which they are), I have to spend even more money to replace then. Then there is the fact I use up all my free time to do videos now. I have put aside friends and family to focus on this because I feel this is my calling to help others. My job is also very demanding and always comes first, so that leaves little time for videos. Thanks!
NOTE:
SQL combines the roles of data definition, data manipulation, and query in a single language. It was one of the first commercial languages for the relational model, although it departs in some respects from the relational model as described by Codd (for example, the rows and columns of a table can be ordered).
