This is a clear and unambiguous error message. The connected database ("File_Name" in ~/login directory) does not have a table named "File_Name".
Did you perhaps create the table in a database that lives in a directory other than ~/login? If so, cd to that directory to run the program -OR- use full path in the SQL instance create command (...
While I'm not staff, I can tell you that the idea of the final project is to do some non-trivial project using any modern programming tools and environments. So, IMHO, yes, it's perfectly acceptable to do your project as you've suggested!
Of course, you're welcome to contact staff too. @curiouskiwi, want to weigh in?
