FIRST code ?

ALTER TABLE movies ADD COLUMN id INTEGER AUTO_INCREMENT PRIMARY KEY FIRST;

If i write the code in this form without FIRST , can i later on fix it to be the the first column or i have to delete the whole column ? ALTER TABLE movies ADD COLUMN id INTEGER AUTO_INCREMENT PRIMARY KEY;

Yes, you can change the column order later.

Now this is assuming you are using MySQL as shown in the videos. Other databases might have a different syntax or may not allow column ordering at all. But for MySQL:

ALTER TABLE movies MODIFY id INTEGER FIRST;
