Create the A3 database using pgAdmin4, then with the query tool open the file init.sql and run it with the pgAdmin GUI. This will generate the Students table and populate it with the sample data.
In a terminal use
python interface.py <arg>
and run the application with the desired arguments:
- C/create runs addStudent(first_name, last_name, email, enrollment_date): Inserts a new student record into the students table.
- R/read runs getAllStudents(): Retrieves and displays all records from the students table.
- U/update runs updateStudentEmail(student_id, new_email): Updates the email address for a student with the specified student_id.
- D/delete runs deleteStudent(student_id): Deletes the record of the student with the specified student_id.
Note: running without an argument will run all the functions on the Students table
Eerror handling is provided shoul you attempt to use an operation without supplying enough arguments
