I want to make a MySQL report on submitted assignments, but it seems a bit hard for me to found the state 'submitted'. I can't find it in mdl_grade_items nor in mdl_grade_grades, but perhaps I'm looking in the wrong direction.
I can try to use the 'timemodified' or 'timecreated', but sometimes they seem to be empty even when a user submitted an assignment.
Any ideas?
