Do we need to know the SQL functions in 7.5? It says in the text to ask our teacher which we need to know.Thank you so much for your help!
To answer your question, all 3 of these functions are fair game for the timed exam and would be good to review and understand before you take it. Since there are only 3 functions it shouldn’t take too long to review. Don’t expect them to show up too much but having a general understanding of them helps! you could use IN while you do your SQL project to help learn it!
Best of luck!
