CodeAlly Coderoad doesn't work

Tell us what’s happening:
I get stuck in the CodeAlly Coderoad. I keep typing the same instruction as the hints. But it still doesn’t work, and shows “bash: ALTER: command not found”.
I had been trying it for few hours, it remains the same.
Can anyone fix this problem?

Thank you!
Your code so far

my code: ALTER TABLE majors_courses ADD COLUMN major_id INT;

Challenge: Learn SQL by Building a Student Database: Part 1

Link to the challenge:

you need to connect to the database, you are in the bash terminal

Thank you so much for your answer. I tried

/c students;

but still cannot connect to the database. Is it the right code to connect the database?

with psql --username=freecodecamp dbname=<database_name>

Thank you for your help!!
