Summary

Instruction

Let's check out the first table, student.

Exercise

Select all columns from the student table. It's a pretty small table that contains only four columns:

  • The student identifier (id).
  • The first name of the student (first_name).
  • The middle name of the student (middle_name).
  • The last name of the student (last_name).

Note: Not every student has a middle name.
