ADD a COLUMN with ALTER TABLE
Oops! We forgot to add the university_shortname column to the professors table. You've probably already noticed:
In chapter 4 of this course, you'll need this column for connecting the professors table with the universities table.

To add columns you can use the following SQL query:
ALTER TABLE table_name
ADD COLUMN column_name data_type;
