I need to do a bulk export of grade_items & grade_grades. I couldn't find much documentation on the grade_items.needsupdate field, and I wanted to know what the implications of what issues might be present in the data if that is set to 1 when I do an export.
The export will essentially be running these queries every 24 hrs.
select * from mdl_grade_items where timemodified > 1235467890
select * from mdl_grade_grades where timemodified > 1235467890
