Hello! I new at SQL and need some help. I have an assignment to make a library in MySQL. Right now I'm at the point of implmenting business rules. One is that I need to create a trigger that won't allow a member to exceed a certain number of loans at a time, based on their category (student = 5, Teacher =10 and Researcher = 20. Can someone help me to do this? I would be forever thankful! Sorry for my bad English, it's not my native language
