推荐答案
Garbage in;垃圾输出。
如果您允许重复的学生ID，您会遇到输入问题。
您没有修复数据输入问题;你阻止它们。
如果你有一个正确的输入编辑/更新，你的问题将不存在。
Garbage in; garbage out.
You have an "input problem" if you are allowing duplicate "student ids".
You don't "fix" data entry problems; you prevent them.
Your "problem" wouldn't exist if you had a proper "input edit / update".
