when I type these code in my sql from sql file exercise it does not work. CREATE TABLE companies ( company_id varchar(255), company_name varchar(255), headquarters_phone_number int(12), primary key (company_id) );

Hi Maxime! Great to have you in the course and thanks for reaching out! I just managed to successfully execute this piece of code, too. Therefore, the error you obtain does not come from the query itself. Can you please support your question with a screenshot/screenshots containing the code and the error message you've obtained, so that we can assist you better. Thank you. Looking forward to your answer. Best, Martin
