3/7/2019 To help students practice SQL syntax, you may log in (using SSH or a similar tool) to and use your local MySQL account to try SQL queries at the MySQL command line.
After you log in to hopper, then
  • start the MySQL command line (#2 on the account paper you are given)
  • copy and paste the text from createHW2tables.txt into the MySQL prompt
  • then download and edit loadHW2data.txt so that it refers to whatever location you plan to put the files of sample data (you may need to edit on your local machine, then copy the file onto
  • put doctor.txt, patient.txt, department.txt at the location you specified in loadHW2data.txt
  • then copy and paste the text from loadHW2data.txt into the MySQL prompt
That will set up sample Doctor, Patient and Department tables, with schemas like in Hwk 2.(Note: for simplification, no foreign keys are set up. And real data is likely to have many more duplicates in human name fields, which a good DBA would think about carefully when writing queries.)
