I have a Database Systems course as part of the cybersecurity classes I have to take. This class involves SQL coding. I made a serious error on one of the continuous problems and then used the command COMMIT. This has sabotaged any future questions, meaning I will not get any future problems, I was struggling with right.  This among a variety of other issues is what I need help with. I have tried using DROP to remove the table to start over with intermittent success but the results are messed up in that way too.  How do I start from a clean slate?
