I am not able to change this initial answer, but if I could it wouldn’t say anything of the such I can assure all. I’m well aware I’ve been being researched for as long as possible to gain all the applicable information and data needed for whatever be the subject matter’s field of interest. This being said… my SQL I’m sure is not the best looking at times, but please keep in mind I am a person who loves to learn as much as I can about a job/career/task/subject/etc. before I’m able to begin to form up the next step I will then take to execute my actions. This is a double edge sword I am well aware of and both sides I love and hate for different reasons. I really do enjoy research, deep research, and my infamous water-rabbit hole high dives. Which consists of the abysmal depths greater than the Mariana Trenches! Apologizing now for rambling Real Time Chat Question- What does BSL4 mean ? Aside from the guess I have which is “Base System Language 4”
