@Karina Gaulin it is a web based user interface for your Database. How are you running your website. On Xampp?
I know about PHPMyAdmin but not sure how to rum those statements in it
Select the database and there should be a SQL tab
you can paste the commands in
so for this section, I couldn'f find the _assets/set_property_dates.sql file, so I need to put those commands into phpMyAdmin instead?
I guess so. Sorry not familiar with the tutorial. The .sql file would be a more convenient tool as you can import a file as opposed to copying and pasting. But you can do both within phpMyAdmin
